Definitions
- the present invention relates to a device for the evaporation of fuels, consisting of a nozzle unit, the one via a fuel feed pump and over a fuel line fuel and separated from it over an air generator and air is added via an air line is, the nozzle unit having a longitudinal axis and has a chamber mounted perpendicular to it, into which the fuel and air through feed channels for mixing is promoted, the feed channels for the Fuel flow tangentially into the chamber, and the Fuel in the chamber thereby in a to the longitudinal axis noticeable vertical rotation offset is and wherein the mixture is expelled through a nozzle channel becomes.
- the heating oils contain i.a. Chlorine and sulfur, the proportion of sulfur all the more is higher, the heavier the heating oil is and can 3.5 wt. % to reach.
- the main problem with current heating systems is that Particle size of the atomized heating oil, which, by means of a Atomization pressure of approx. 15 bar to 80% between 40 and 80 Micron lies.
- the heavy heating oils In order to reduce the viscosity of the heavy heating oils, they are heated to 50 ° C to 100 ° C, which is the particle size influenced, but not enough to to bring about maximum combustion, not to mention that heating the heating oil consumes large amounts of energy.
- French Patent No. 903 293 describes a device which has the features of the preamble of Claim 1 includes.
- the device has a nozzle unit on which with concentrically arranged feed channels is equipped for fuel and gas that is tangential directed channels open into a vortex chamber the fuel-gas mixture by means of a nozzle channel is expelled. Both the gas and the fuel are fed tangentially into the chamber, where they are rotating. Because the gas and the Fuel and have the same direction of movement move more or less parallel next to each other, can not be fine and continuous through this arrangement Mixing of fuels and gas can be achieved what has a negative effect on the particle size when exiting and excludes optimal combustion.
- French Patent No. 809 455 the fuel and the air together via helicoid Grooves in the nozzle unit directed to the discharge channel. Also here fuel and air are mixed only moderately well. In addition, there are no means provided here for the compressed air in the fuel can compress what for Evaporation of fuel is very important.
- the present invention is based on the object to remedy these disadvantages of the known device and Vaporizing fuels instead of atomizing them, whereby the smallest possible particle size can be achieved.
- this object is achieved by a device for the evaporation of fuels and the Feeding of combustion air as defined in claim 1 is solved.
- the air used for evaporation at the same time one Part of the combustion air, being by an ultrafine Particle size a faster evaporation and thus better combustion is brought about and thus the undesirable residues, especially the NOx, can be limited.
- the device according to the invention is based on a device for atomizing liquids with the addition of compressed gas, which with a pressure of only 1 bar a SAUTER-mean particle size from 21.08 micron.
- a SAUTER-mean particle size from 21.08 micron.
- the particle size is reduced significantly, so that one can speak of evaporation.
- This evaporation is the basis of the inventive Device and ensures optimal combustion.
- Fig. 1 shows a nozzle sleeve 1 in which a nozzle core 2 is stored, which has a mixing chamber 3, in which compressed bores 4 lying parallel to the core axis Air and via feed channels 5 and tangential channels 6 (see also Fig. 2) pressurized heating oil flows in, so that the heating oil and the compressed Can mix air there.
- the nozzle sleeve 1 has an expansion chamber 7, a compression chamber 8 and a nozzle channel 9.
- the depth of the expansion chamber 7 and the compression chamber 8 determine the length of the nozzle channel 9, a short nozzle channel 9 gives off a wider cone than a long one.
- 4 shows a conical Nozzle channel 10, which gives off an even wider cone than an equally long but cylindrical nozzle channel 9.
- Die Diameters of the nozzle channels 9 and 10 determine the amount of heating oil that is emitted per unit of time: with the same Pressure is small with a small diameter, being but the diameter of the nozzle channels 9 and 10 is not smaller than 0.30 mm and since you can use the evaporating air clean, they remain constant throughout.
- the feed channels 5 of the nozzle core 2 open into the tangential channels 6, which open into the mixing chamber 3, so that one of the feed channels 5 and the tangential channels 6 incoming heating oil is pushed into the mixing chamber 3 is that there is a rotating motion along its wall into which the compressed air is transferred the hole 4 is pressed vertically, whereby it then after a first compression phase in the mixing chamber 3 can relax in the expansion chamber 7 afterwards highly compressed in the heating oil in the compression chamber 8 to become.
- FIG. 5 shows another embodiment of a nozzle unit, from a nozzle sleeve 11 and a nozzle core 12 existing, which is used especially for fuels, where the nozzle unit is the viscosity of the heating oil must be adjusted exactly, e.g. with heavy heating oils. If the nozzle unit of FIG. 1 had a viscosity of more than 10 centipoises, the Modifications to both the feed channels 5, the tangential channels 6 and the mixing chamber 3 of the nozzle core 2, such as also take place on the expansion chamber 7 of the nozzle sleeve 1. 5 are the modifications easier.
- the feed channels 13 are located and the tangential channels 14 in the nozzle sleeve 11, wherein the tangential channels 14 open into the compression chamber 15, which has the nozzle channel 16.
- the air gets over Bores 18 into the mixing chamber 17, which with the Compression chamber 15 communicates. Do you want this Adjusting the nozzle unit to a higher viscosity is enough it to keep the mixing chamber 17 of the nozzle core 12 lower and enlarge the diameter of the holes.
- a pressure vessel 19 In the pressure vessel 19 there is a float 23 with a needle 24.
- Der Lid 20 is with a pressure relief valve 25 and Air outlet 26 provided.
- At the bottom of the pressure vessel 19 there is a heating oil inlet 27, a heating oil return 28, which is temporarily closed with the needle 24 and the Heating oil outlet 29.
- a heating oil, not shown, is by means of a pump 30 is conveyed into the pressure vessel 19, while at the same time the compressor 21 the pressure vessel 19 sets at atmospheric pressure, the amount of pressure with the pressure relief valve 25 is adjustable.
- the Float 23 pulls the needle 24 out of the return 28 as soon as a predetermined amount of heating oil in the pressure tank 19 so that the excess heating oil is returned to the intake pipe the pump 30 flows back.
- the nozzle sleeve 1 (11) with the nozzle core 2 (12) is in a distributor block 31. This is via the air outlet 26 and a solenoid valve 32 supplied with compressed air, the volume of which with a Needle valve is adjustable.
- the heating oil is, under identical Pressure like the air, over the heating oil outlet 29 and a solenoid valve 34 pressed into the distributor block 31, the fuel oil volume using a needle valve 35 is adjustable.
- the distributor block 31 carries a hollow combustion cylinder 36, in the direction of escape of the nozzle axis is provided with a sieve 37 and side holes 38 has, with a slide 39 more or less are closable. Secondary combustion air, coming from a blower 40, in the hollow cylinder 36 and thus in the vaporized, already fuel oil enriched with primary combustion air, blown will.
- the pressure relief valve 25 can consist of a membrane, which is located in an electrical by means of a magnetic core Coil lifts under a preset current and excess pressure can escape, such a design, provided with a potentiometer that the current of the The spool controls makes it easier to adjust the pressure level essential as there is only a change in current in the coil needed to resist the resistance of the membrane to increase or decrease the pressure.
- An essential one The advantage of this solution is that the amount of heating oil per unit of time using the pressure in the pressure vessel 19 can be infinitely adjusted without reducing the particle size to change significantly.
- Fig. 9 shows without taking any scale into account wear, an extremely advantageous embodiment of the inventive Contraption.
- the main difference, compared 8 is that the Hollow cylinder 36 with, in this embodiment, nine tubes 41 is replaced, the free ends 42 are closed.
- the Tubes 41 have bores 43 and a blower 44 fills the tubes 41 with compressed air, which via the bores 43 is blown into a flame, not shown. thanks a thread 45 with which the tubes 41 in a distribution plate 46 screwed and blocked by nuts 47, it is possible to blow the bores 43 as desired set, i.e., the one coming from the blower 44 Air can enter both the axis of the flame, as well or less tangent to it, blown, to specifically control a swirl. You can too thus a mixture of axis blowing direction and tangential blowing direction to reach.
- the bores 43 one tube 41 is offset from that of another tube 41 be attached.
- FIG. 9 shows two different ways.
- the housing 49 of the blower 44 has openings 50 which are connected by means of a sleeve 51 are shielded from the outside air.
- a sleeve 51 is shielded from the outside air.
- the exhaust gases are via outer tubes 53 which are provided with holes 54, and openings 50 of the housing 49 sucked in and in the manner described in the Blown flame.
- Supply of secondary combustion air via the tubes 41 has the advantage that the cold coming from the blower 44 Outside air is heated in the tubes 41 and thus the Flame cannot cool down, causing insufficient combustion due to the flame cooling down and thus lowering it heat evaporation of the heating oil is avoided.
- the diameter the nozzle channels 9 and 16 is at least 0.4 mm can practically never clog, if only because of the Blown nozzle 1 (11) before and after the combustion process becomes.
- their cross sections are approx. 7 times larger than those of the mechanical ones Atomizer nozzles, the hourly rate be kept at 0.5kg and, as described, with only an increase in air pressure in the pressure vessel 19 can be continuously increased to 1.1kg.
