Description

Explosion engine

Technical field

Explosion engine is as a kind of motive power machine device, is a kind of chemical energy to be transformed into prime mover of mechanical energy, and the elementary cell of this mechanical work is: explosion engine.It is with the present main hot machine that utilizes, internal-combustion engine for example, and steam turbine, air breathing engines etc. are the same, all are to rely on High Temperature High Pressure working medium to finish the hot merit conversion, to realize chemical energy to heat energy, mechanical transformation of energy.

Background technique

Along with the construction of socialist market economy and the raising day by day of living standards of the people, make people urgent day by day to the demand of the energy, not only improve.And mainly be to be undertaken by the burning of fuel to the utilization of the energy at present.For example: adopt the initial steam pressure of the steam turbine of subcritical pressure boiler to reach the 15.69-17.65 MPa, 535 degrees centigrade of initial steam temperatures make the thermal efficiency reach nearly 40%.And the efficient of boiler and other factors are all influential to it.Because steam turbine is the same with other hot machine all is that the energy that relies on burning to produce does work.Required like this firing rate is inevitable very big, and corresponding exploitation is also very big with freight.And combustion process can cause corresponding pollution of atmosphere.The basic imagination of invention internal-combustion piston engine was exactly to originate to want to utilize the gunpowder explosion common bluebeard to get power originally, but the common bluebeard is not successful because of powder burning is difficult to control.(see: Encyclopadia Sinica mechanical engineering internal-combustion engine) present utilization to gunpowder has two kinds, and a kind of is as propellant powder, and another kind is called propellant agent, and they all are to utilize the burning generation high temperature and high pressure gas or the high velocity air of gunpowder to do work work.Orthodox explosive blast be chemical energy to mechanical transformation of energy, every power of the Turbo-generator Set of current maximum is no more than 10 ⁶Kilowatt, and 1kg TNT is 1.65g/cm at degree of packing ³Under the quick-fried condition of spherical cartridge bag center, power is 5.65*10 ⁸Kilowatt, the power of (blast of Encyclopadia Sinica mechanics) visible blast is very large, coming the utilization for the energy by burning is very low than the energy that blast produces.But the utilization of the energy that blast is produced, but be very difficult, mainly be because explosive, particularly violent quick-fried medicine, to mechanical sensitivity, heat sensitivity, and fusing point is all higher, very dangerous and be difficult to control.So now pay attention to utilize its explosion property more, its high-energy controlled and utilized and ignored.The idea that people are general also be away from originally the invention internal-combustion piston engine make the imagination of power of gunpowder.Be only limited at blasting engineering, blast processing, the conventional weapon propellant powder, mine and water conservancy construction or the general safety problem of just regarding are considered research.And utilize subject matter to be because difficult to its control to explosion energy.Chemical explosion is carried out in two ways, a kind ofly is called detonation, and its reaction velocity of propagation is much smaller than the velocity of sound (331.36m/s), and influenced by ambient condition, density on the reaction surface is preceding littler than reaction, and the particle velocity direction is opposite with the velocity of propagation direction, and another kind is called detonation, claim pinking again, its reaction velocity of propagation is much larger than the velocity of sound, and speed is fixed, and not influenced by ambient condition, density on the reaction surface is greater than before reacting, and the particle velocity direction is consistent with the velocity of propagation direction.Usually the detonation system of liquid, solid phase is called explosive.Because the violent quick-fried medicine of solid is up to the high C-J detonation pre ssure of tens of lucky handkerchief levels, and the character of high mechanical sensitivity, cause the control that is difficult to it.And the system that produces detonation can be: gas phase, liquid phase, solid phase, or the system of mixing phase composition.Detonation pressure process height (condensed phase detonation can reach the magnitude of 10 lucky handkerchiefs), temperature height (10 ³Open), the endurance short (microsecond magnitude), every square centimeter of detonation wave front power of high explosive is up to 10 ¹⁰Watt.(detonation of Encyclopadia Sinica mechanics), but we find that also the C-J detonation pre ssure of gas phase detonation is not very high, its C-J detonation pre ssure how in the 1-4 MPa, far below the C-J detonation pre ssure of explosive up to the lucky handkerchief of 10-35.(detonation of Encyclopadia Sinica mechanics).Comparatively speaking, be comparatively feasible by utilization to the gaseous substance that can produce detonation.The kind of gas that can produce blast is a lot, and the source is very extensive again.And a lot of liquid phases, solid phase organic substance and metallic dust magnalium and industrial alloy thereof or the like can produce blast.So can be by the manageable control that can produce volatile material equally being reached utilization to explosion energy.And be the research of elementary gas blast to the research of gaseous detonation now or also all be more deep to the research (Chinese science B collects the explosion limit and the container factor thereof of the 32nd volume polynary explosive mixed gas of the 1st phase February in 2002) of multi component mixed gas body blast.The explosion limit scope of all gases has nothing in common with each other, and its concentration that produces maximum explosion pressure is also different because of the gas face.But its force value is all much smaller than the pressure that detonation takes place.For example: the constant volume explosion pressure of 10.1% gas and Air mixing gas is approximately 0.71-0.81Mpa.1952 Shu Erci-appearance Hough (Schultze-R honhof) has carried out twice gas density 9.5%, accumulation region 300m at abandoned mine of the U.S. large-scale explosion test, it is 9.8% o'clock generation maximum explosion pressure in concentration that blast records surge pressure 1.01Mpa. methane, is 7.17kg/cm ²And CH ₄+ 2O ₂The C-J detonation pre ssure of mixed gas (288 open, 101325 handkerchiefs) is between its limiting value that produces blast, for example: H for the limiting value that 3.04Mpa. produces detonation ₂The aerial detonation limits value of+CO is between 19--59%, and its aerial explosion limit value is between 4--75%.This shows, mainly should be embodied in utilizing in the process of energy that detonation is produced to the utilization of explosion energy.And the explosion limit scope of gas has confidential relation with each side such as its initial temperature pressure.In the material application facet, the firing chamber of solid propellant rocket has also reached bears high temperature (2500---3700k) and high pressure (10 ⁶---2*10 ⁷Handkerchief) ability.Its pressure tolerance head and shoulders above the scope of gas phase C-J detonation pre ssure.Aspect computer controlled automatic, the electronic ignitin system under automatic control technology such as the microcomputer control etc. are in industrial also extensive use.

Summary of the invention

(1) technical problem that will solve: present various hot machine to the utilization of the energy mostly be the energy that produces when utilizing fuel combustion externally acting realize.And the energy that is discharged by burning is very limited.On the one hand, the burning consumption is very big, and pollutes very heavy.On the other hand, its exploitation and cost of transportation are also all quite big.Aspect aircraft, because its propellant agent is to utilize the firmware fluid combustion to advance, it equally also is very big to the Fuel Demand amount.Cause the huge of volume weight like this, correspondingly its mobility is exerted an influence.Along with being extensive use of of the nitroglycerine of Nobel in 1866 development, its huge power makes people produce the idea that its energy is used.Just be based on this imagination, just inventing internal-combustion engine.In the fifties, the thermomechanics expert of the Soviet Union also pointed out the practical prospect that drop detonation is possible, but all the time, the practicability of also all failing to realize.In order to realize utilization to explosion energy.Explosion engine problem to be solved is exactly by to effective control of the explosive working medium such as gas phase that can produce blast and make its blast produce ceiling capacity and safety, thereby effectively output reaches the externally utilization of acting of energy that the working medium explosion time is produced.Or directly utilize its reaction thrust to advance (aircraft propelling, principle of propeller is the same with jet propulsion engine, just difference is the reactive mode difference of working medium on the energy utilizing, jet propulsion engine is the energy output that utilizes fuel combustion to produce, explosion engine then is the energy output that utilizes working medium blast (detonation) to produce, this is its with fundamental difference of the hot machine in using at present), or utilize the output (utilizing the rotating machinery power device) that produces mechanical energy of its thrust.Because explosion energy is huge,, for utilizing fuel combustion, can effectively reduce the Fuel Demand amount so its output power is very big.Greatly the energy saving resource improves its utilization ratio, relatively alleviates the pollution of environment.Also reduce simultaneously the volume and weight of aircraft relatively.Improve its mobility.

(2) technological scheme:

Explosion engine be in fully machine calculate machine the time work under the real state of a control.Temperature by various biography inductors positive activity state when detected, flow, pressure, monitor messages such as rotating speed are transformed to analog signalses such as the desired curtage of computer through transmitter, these signals by sampler adopt as required into, and through amplifier, the A/D converter amplification is converted to corresponding digital amount signal, convert the manageable numerical information of computer to, under the computer digit program control, the conversion of the information via D/A converter after machine is handled as calculated converts corresponding electrical signal to, again after the amplification of amplifier, control command by actuator's object computer, to reach to solenoid valve the input flow rate of working medium, pressure, the rotating speed of explosion engine rotating machinery power device, mass flow controller, computer control do not have distributor formula direct ignition system DLI, the real-time control of plug ignition time etc.Photoelectric tachometric transducer as calculated after the machine routine processes, produces a needs speed governing, speed stabilizing, or the time real control information of quickening to the monitor message of the speed of explosion engine rotating machinery power device under state of a control.And correspondingly produce a flow control information.The controlled flow quantitative change of flowmeter survey is changed into can be directly and the physical quantity of quantitative comparison (generally being voltage), when having deviation between the output of flowmeter and the control information amount, regulator is handled deviation signal, and be defeated by flow regulator, flow regulator is the opening degree of regulating valve in view of the above, to change ducted flow, make it to be tending towards expected value.And remain near the expected value.By to the control of working medium flow to realize to the working medium incoming pressure input quantity, the control of working medium reaction density.And then realize reacting the control of output power.The finally control of real-turn speed when realizing to explosion engine rotating machinery power device.In order to realize utilization to explosion energy, working medium should select to produce explosive reaction, and require to be in the certain controlled safety range, key reaction working medium and oxygenant can separate so that the working medium of safe transport.Its source is very extensive, for example: H ₂, C ₂H ₂, CO, CH ₄, NH ₃, liquid hydrogen, liquid oxygen, rock gas, coal gas, biogas, and the by-product of industrial department as: liquefied petroleum gas (LPG) (LPG), hydrogen etc. reach nearly hundred kinds of working medium.Explosion engine material selection austenite Oxidation Resistant Steel is as: steel grade such as Cr18Ni25Si2 or 1Cr25Ni20Si2 or use refractory alloy; Adopt the solid forging method, spark plug and nozzle are adopted positive drive type sealing, built-in refractory layer.The explosion engine body is made up of reduce pressure loader, explosive reaction chamber, nozzle of special use.The thrust that explosion engine produces is calculated by following formula:

F thrust=M Ve+Ae (Pe-Pa)

Wherein: M is the mass flow rate Ve of working medium, and Pe is the flow velocity of outside nozzle working medium, static pressure

Pa is that the nozzle exit section is long-pending for barometric pressure Ae

At first open the source of the gas electromagnetic valve switch and begin air inlet by computer control, start two stage compressor simultaneously, the end pressure of key reaction working medium and oxygenant is transferred to respectively a little less than blast (detonation) reaction pressure value place (between the 0.5---3.0MPa), in order to the flow rate of raising gas, but must not be higher than real at that time explosion pressure.The adjusting of pressure by microcomputer according to the explosion engine pressure transducer measure by governor pressure, and convert the signal form of being convenient to utilize to, as voltage, electric current etc., comparer will reflect that the signal of pressure size compares with setting value, produce deviation signal, and deviation signal affacts on the regulator by pressure controller, change the pressure of measured point according to the direction of eliminating deviation, it is adjusted near the given expected value.Here to eliminate self-oscillatory possibility with the way of limit feedback.React working medium in actual applications because the main gas cylinder equal pressure container that uses as main air supply source, uses the process of compressor generally not need.The mass flow controller controlled in real time by computer of reaction working medium enters special-purpose decompression loader, and it is the influence to working medium of the high pressure that produces when reducing to react that special-purpose decompression loader mainly acts on.Working medium enters reaction chamber through mixing nozzle after the mixing, reaction chamber bears the High Temperature High Pressure that the working medium explosion time produces, and is generally cylindrical.Enter the simple substance that just becomes after the mixing of reaction chamber in the explosion limit scope that is in that can produce explosive reaction, explosive working medium such as mixed gas, after reaching blast controlled conditions (reach control flow rate and be in its controlled explosion limit scope), by the computer starting electronic ignitin system, final controlling element control plug ignition, produce explosive reaction, the chemical energy of reaction gas is converted into the high speed and high pressure air-flow, or detonation wave, quicken to spray through the jet pipe expansion with hypervelocity (1500-3000m/s), according to momentum conservation law, reaction force acts on the explosion engine along the air motion opposite direction, directly produces reaction thrust and advances.Thrust that also can be by explosion engine is translated into exportable mechanical energy output to the effect of rotating machinery power device.The rotor of explosion engine rotating machinery power device is made up of with the explosion engine that is contained in the generation thrust on the main shaft Flywheel disc the main shaft of monobloc forging.So that when explosion engine produces thrust, can promote main axis rotation.The longitudinal thrust of explosion engine is converted into rotating force output.The rotor of rotating machinery power device should have certain rigidity, and its working speed should be avoided critical speed of rotation, must be after the rotor assembling through accurate dynamic balancing, vibrate when preventing to move.Two ends of rotor is supported by radial bearing, for bearing axial pushing force should be equipped with thrust-bearing, to fix its axial position.Bearing oil is supplied with by main oil pump, has auxiliary oil pump simultaneously, and rotor one end has coupling, for the usefulness that connects generator or miscellaneous equipment.Its a whole set of control system also comprises supervision and measurement noise, vibration, gaseous detonation content, devices such as ventilation.In the rotating power machinery device, its single-stage simple structure, major part only is made up of the explosion engine and the main shaft that are contained on the Flywheel disc.In order to improve its power, main aspect should make reaction be in the detonation state that it produces ceiling capacity, to utilize its maximum detonation energy as much as possible.Secondly can be by quantity and the employing multistage that increases explosion engine.The air inlet inlet opening of explosion engine rotating machinery power device and main shaft are on the same horizontal axis, to guarantee when the high speed rotating and outside steady the butt joint.And only as propulsion functions the time because machinery without spin then need not considered this factor.Itself and the interface of the outside pipeline that joins when working medium input rotating machinery adopt mechanical seal, and the double-skin duct form that socket-connects guarantees to import simultaneously two kinds of working medium of different nature.Its internal layer closed conduit is used for importing key reaction working medium, establishes outer closed conduit outside its pipeline again, is used for delivery of oxidizing agent working medium.For example: oxygen, air etc.The special use that suction tude reaches and suction tude is joined decompression loader to the explosion engine air feed all is fixed on the Flywheel disc.Its spark plug wire route brush is introduced the rotating machinery device.Rotating machinery power apparatus system material selection Precipitation-hardening Stainless Steel is as 0Cr17Ni7AL or 0Cr15Ni7Mo2AL.Explosion engine is realized uninterrupted continuously input working medium (mainly being gas phase) to the reaction under high pressure chamber by special use decompression loader.Being the millisecond magnitude when detonation is reacted during the explosive reaction, then is the microsecond magnitude when detonation is reacted.Only at explosion time, because the input of working medium is temporarily interrupted in the high pressure meeting, but reaction (nanosecond) later, and working medium then will continue input, can reach to make to react to be similar to uninterruptedly to carry out continuously.In order to raise the efficiency, just must accelerate course of reaction, then must strengthen air inflow, promptly strengthen the diameter of supplying tube.Control its explosive reaction simultaneously and react transition to detonation.Because explosion engine also can produce a large amount of heat energy in the course of the work except producing kinetic energy, for example: 2H ₂+ O ₂The mixture reaction time can discharge the quick-fried heat of 13284 Kilojoule/kilograms, so be very much necessity to making full use of of this part heat energy.And it is very important to its cooling.Employing convection current cooling, the cooling of book film, the thermal-protective coating cooling, sweating cooling etc. all can.The power of explosion engine mainly depends on following factor: 1. produce the character of blast working medium own, and temperature, pressure produces the threshold concentration value of maximum C-J detonation pre ssure, the influence of working medium ratio of components concentration; 2. container factor (linear dimension, geometrical shape etc.); 3. working medium reacting dose; 4. in the operation range cycle (inferior/second), mainly by the input speed of working medium, input quantity determines for it; 5. every group of quantity of the explosion engine that adopts of rotating power machinery device and progression; 6. other inert gas and the catalyzer of nitrogen that mixes in the gaseous mixture and adding; 7. exhaust loss; 8. the friction windage loss of Flywheel disc; 9. Fan Ying stage and no thoroughness; 10. water vapor, methane etc. are to the interception of multi component mixed gas body, and damping effect, the influence of oxygen content etc.

Explosive working medium must be controlled it and be in not explosibility state before the input reaction chamber, for example: when key reaction working medium is used gas phase mixture CO+H ₂When adopting pressurized air to react work, then should control the upper limit of the concentration of key reaction working medium, to guarantee its Security greater than the explosion limit of its 4%--75% with oxygenant.And should notice that explosion limit can broaden because of its scope of environmental change.In the process of input reaction chamber, just be mixed into the explosive working medium that is in control blast state through nozzle.Special-purpose decompression loader simple structure, every has a lot of tiny transfer port and rear cavity to constitute by the front portion, and multi-disc phase closed assembly is gone in the anti-high pressure sealing container of both ends open.Selecting the austenite Oxidation Resistant Steel for use is material, adopts the burst manufacturing, and the lamination moulding is installed its front and back adjacent apertures of back and must not be positioned at same horizontal axis, and should stagger, to avoid true connection of high speed and high pressure strength stream.Its hole can not be too small, otherwise carbon distribution easily stops up.Its working principle is: when reaction chamber is blasted reaction, the high speed and high pressure air-flow that produces enters the sealing expandable cavity from the high pressure side with high flow velocity through tiny throttle diameter, the speed energy that forms when flowing through the aperture with spent gas, so through repeatedly throttling and expansion produce resistance, so as to reaching air-flow is slowed down, the purpose of decompression.To avoid explosive reaction to the influence of working medium (shockproof wave pressure, anti-burning, anti-backflow).After design rationally, this process is not very for influencing the flow of working medium input reaction chamber.The size of its flow is by the diameter of aperture and decompression loader, and the sheet number of selecting for use is regulated.Can improve its flow rate by giving the working medium supercharging simultaneously.Because the imperfection of explosive reaction, no thoroughness reaches the inflammable and explosive of gas working medium, and ignition system should all adopt the blast shield measure.In order to prevent the explosion risk of working site, essential its ventilation of reinforcement because gas and liquid can produce static when flow at high speed, might cause input pipeline generation electrical spark explosion phenomenon, so to input pipeline good earth must be arranged.Prevent the generation of static.For decomposition reaction is the gas of exothermic reaction, as: acetylene etc. are when 1.5Mpa pressure is above, and the danger of easily blasting must its Security of idea.Simultaneously owing to will produce very big noise during blast (detonation),, can use catalyzer and to entire field sound-insulating cover in addition in order to reduce on-the-spot noise intensity.Silencing apparatus is set, the noise reduction hole.The ignition interval of spark plug (power is not less than 50w, and 20--40kv, electrode gap 0.4--0.7mm, knock resistance want high) depends primarily on the time that the working medium input quantity reaches reaction controlled conditions.

(3) beneficial effect:

Velocity of propagation of flame is 10 during fuel combustion ^-4--10 metre per second (m/s) magnitudes, and the detonation wave velocity of propagation is 10 ³--10 ⁴Magnitude, the chemical reaction process in the blast releases energy at a high speed, and every power of the Turbo-generator Set of current maximum is no more than 10 ⁶Kilowatt, and the power of 1kg common industrial explosive blast be 100,000,000 kilowatts-(blast of Encyclopadia Sinica mechanics).When using suitable reaction gas, can there be environmental pollution problem (for example hydrogen is done main reaction working medium, and oxygen is made oxygenant) fully.The steam turbine volume is huge at present, and corresponding corollary equipment and maintenance thereof are complicated, and it is by fuel combustion mode to the utilization of the energy simultaneously, and the fuel combustion generating is very big to pollution of atmosphere, and the consumption of fuel is also very big, and cost is very high.The main-body structure of explosion engine is simple, safeguards, when using the low working medium of explosion limit, the use amount of reaction working medium still less, energy saving more.Compare with steam turbine, its power is big, and starting control rapidly, and is simple, convenient, is well suited for industrial electrical production aspect.Explosion engine is compared with the hot machine that utilizes fuel combustion to discharge heat energy at present, the explosion engine utilization be working medium blast (detonation) time energy output that produces, because explosion energy is huge, so its output power is very big, so greatly improved to rate of energy.For utilizing fuel combustion, because be working medium with the gaseous fuel mainly, in general its cost is lower, and noxious emission is also less, thereby has good economic benefit and social benefit.Can effectively reduce the Fuel Demand amount.Greatly the energy saving resource improves its utilization ratio, relatively alleviates the pollution of environment.Be used in the propelling of aircraft, can reduce the Fuel Demand amount effectively, also reduce the volume and weight of aircraft simultaneously relatively.Thereby increase its mobility, enlarge its flying distance.

Embodiment

Explosion engine compares as aircraft propelling aspect that to be used for doing the rotating machinery power device simple, and its working principle is the same, and is just simpler in the input of working medium.So main explanation utilizes explosion engine to advance the rotating machinery power device, produce electric power output with drawing generator.

Utilize the measurement of mass flowmenter to gas flow, its signal is reached preamplifier, its electrical signal is imported computer through the conversion of modulus converter A/D again.Through after the processing of computer, send the conversion of command information through D/A converter, convert electrical signal to, carry out its order by final controlling element.Spark plug discharge time, by computer monitoring and control, required Control Parameter is realized by software gas flow (by mass flow controller control).A pressure transducer is installed on each explosion engine body, and a pressure transducer is installed by every grade of each suction tude portion of rotating machinery power device.For the flow control aspect, influence each other owing to often exist between the flow control system of same pipe-line system.Thereby can make the performance depreciation of whole flow control system, thus stability and other control performance in order to guarantee system, also in order to simplify its structural complexity to greatest extent.So should control the input total amount of calculating each working medium respectively to input working medium.For the uniformity of the working medium input quantity that guarantees each explosion engine, in software control system, should determine the adjusting rule of whole system by the design principle of multi-variable system.Guaranteeing all to adopt the highi degree of accuracy throttling element to measure its working medium input quantity to each explosion engine supplying tube under the equally distributed condition of power pressure, to guarantee to reach the control requirement.Nozzle adopts two to hit unlike-impinging injector element.The reaction chamber type of cooling adopts the regeneration cooling, as freezing mixture, makes it flow through coolant jacket with a kind of reaction working medium, enters reaction chamber through special use decompression loader then.The rotating machinery power device adopts multistage operating, and output power is always multistage in groups as required to be installed and used in order to improve in the practical application.In this example, every grade is used five explosion engines to work simultaneously altogether.Totally seven grades.Be installed on the Flywheel disc, the diameter of Flywheel disc is 160mm, because of making high speed rotary motion, should consider the intensity and the density of its material, selects the little high-strength material of density for use.As: when adopting precision casting, can use cast aluminium alloy ZLZn ₅O ₆The volume of each cylindrical reaction chamber is 30000ml, highly is 40cm, and wall thickness is 20mm.Jet pipe length is aided with aluminium oxide (AL for the 40cm reaction chamber wall ₂O ₃) do refractory material, and in the reaction chamber wall skin-material, dissolve in the catalyzer of platinum black powder when reacting, so that reaction can undisturbedly be carried out, detonation does not take place.Reducing noise.Key reaction working medium is selected the canned hydrogen of compression container for use, and (explosion limit 4.0%---75%, requiring the percentage of control itself and oxygenant is about 18.3%---59%, to realize the detonation reaction, produces maximum explosion energy output.Oxygenant is selected air for use.Utilizing secondary formula turbocompressor is the air-flow with certain incoming pressure with air compression.Through (the whole atmospheric pressure of input reaction chamber requires to be lower than reaction pressure) input rotating machinery power device after the pressure regulation under the computer control.Its input end is connected with rotating machinery by motive sealing.The effect of key reaction working medium hydrogen has two aspects.Be to use on the one hand as freezing mixture.Be to participate in reaction on the other hand as main reaction working medium.Motive sealing place at Working medium gas input rotating machinery device for safety, prevents the leakage of key reaction working medium, and the input of air presses the input that should be a bit larger tham key reaction working medium to press.Play a negative pressure protection.During work, after machine calculation machine starts the source of the gas electromagnetic valve switch, the overanxious purification of working medium drying tower back (mainly is the drying of drying, lower water content) under the control of mass flow controller, (accurately the input quantity of working medium is reacted in control, and pressure is to reach its concentration of dynamic control) key reaction working medium wherein is to enter reaction chamber by different pipelines with pressurized air.Wherein hydrogen flow is through coolant jacket, enters reaction chamber after reaction chamber is cooled off.After working medium flow reaches control criterion.Be after the feedback signal of flowmeter reaches controlled conditions, computer sends firing command, convert thereof into current signal by D/A converter, after amplifier amplifies, start spark plug control power supply (electronic ignitin system DLI), realize once igniting, reach explosion caused reaction, finish the one action circulation.Explosion time, because the pressure that blast produces makes special-purpose decompression loader carry out temporary transient interruption of the input of working medium, (ns) working medium then will continue input after blast, enter among the work cycle next time.Reach and it seems to be similar to continuously from process and carry out.The rotating machinery device is then incited somebody to action rotation work continuously because of action of inertia.Starting process is because the violent and time of explosive reaction of short duration, and parameter changes greatly, so its course of reaction should be begun to start by minimum explosion limit value place, transfers to maximum explosion limit value more step by step.I.e. about 40% detonation response value place.The startup of its working speed is quickened, and speed stabilizing, deceleration adjustment process be by computer control, realizes regulation and control to its Control Parameter by software.Control procedure to the rotating machinery power device rotary speed is by the monitoring of photoelectric tachometric transducer to its rotating speed, reaches control to real time reaction concentration and reacting dose by computer by the control to the flow of working medium, with the control of final realization to rotating speed.Because be subjected to the continuous impact of detonation wave during the work of explosion engine reaction chamber.Its physical property, mechanical property, mechanical property (creep strength, toughness, fatigue strength etc.) can change in through the using process during certain, so should be taken into account its convertibility in the design process.

Because hydrogen producing technology also is far from reaching the level of practicability now, so the above just explanation of principle.Be mainly used in the practicability aspect also should with other gas as: natural gas, coal gas etc. are main.
