Abstract
Description
- The present application relates generally to pulse detonation combustors and systems and more particularly relates to the use of pulse detonation combustors for highly efficient heat exchangers such as boilers and the like.
- Known pulse detonation combustors generally operate with a detonation process having a pressure rise as compared to conventional engines operating with a constant pressure deflagration. Specifically, air and fuel are mixed within a pulse detonation combustion chamber and ignited to produce a combustion pressure wave. The combustion pressure wave transitions into a detonation wave followed by combustion gases that produce heat and thrust. As such, pulse detonation combustors have the potential to operate at higher thermodynamic efficiencies than generally may be achieved with conventional deflagration based engines.
- Recent developments in pulse detonation combustors have focused on practical applications such as generating additional thrust/propulsion for aircraft engines and improving the overall performance in ground based power generation systems. Pulse detonation combustors also have been used as a means for highly efficient boiler cleaning and the like.
- Industrial boilers operate by using a heat source to create steam from water or another type of working medium. The steam may be used to drive a turbine or another type of a load. The heat source may be a combustor that burns a fuel-air mixture therein. Heat may be transferred to the working medium from the combustor via a heat exchanger. The efficiency of the boiler or other type of heat exchanger is based in part on the heat transfer rate to the working medium. In general, heat transfer rates for boilers and similar devices tend to be much higher for turbulent flows as compared to laminar flows.
- There is thus a desire to adapt the highly efficient pulse detonation combustors for use in heat exchangers such as boilers and the like. The use of such a pulse detonation combustor should provide a higher heat transfer rate, with less fuel consumption, and while being more compact in size as compared to conventional boilers and the like.
- The present application thus provides a pulse detonation combustor heat exchanger. The pulse detonation combustor heat exchanger may include one or more pulse detonation combustors creating combustion gases therein, one or more inner pathways positioned about the pulse detonation combustors, and a working medium flowing in the inner pathways so as to exchange heat with the combustion gases in the pulse detonation combustors.
- The present application further provides a pulse detonation combustor boiler. The pulse detonation boiler may include one or more pulse detonation combustors creating combustion gases therein, a number of boiler tubes positioned about the pulse detonation combustors, and a working medium flowing in the boiler tubes so as to exchange heat with the combustion gases in the pulse detonation combustors.
- The present application further provides a pulse detonation combustor heat exchanger. The pulse detonation combustor heat exchanger may include an outer chamber, one or more pulse detonation combustors positioned within the outer chamber creating combustion gases therein, one or more inner chambers positioned within the outer chamber, and a working medium flowing in the inner chambers so as to exchange heat with the combustion gases in the pulse detonation combustors.
- These and other features and advantages of the present application will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

FIG. 4 is a schematic view of a pulse detonation combustor boiler as may be described herein. -
FIG. 5 is a side plan view of the pulse detonation combustor boiler of 4. - As used herein, the term “pulse detonation combustor” refers to a device or a system that produces both a pressure rise and a velocity increase from the detonation or quasi-detonation of a fuel and an oxidizer. The pulse detonation combustor may be operated in a repeating mode to produce multiple detonations or quasi-detonations within the device. A “detonation” may be a supersonic combustion in which a shock wave is coupled to a combustion zone. The shock may be sustained by the energy release from the combustion zone so as to result in combustion products at a higher pressure than the combustion reactants. A “quasi-detonation” may be a supersonic turbulent combustion process that produces a pressure rise and a velocity increase higher than the pressure rise and the velocity increase produced by a sub-sonic deflagration wave, i.e., detonation and fast flames. For simplicity, the terms “detonation” or “detonation wave” as used herein will include both detonations and quasi-detonations.
- Exemplary pulse detonation combustors, some of which will be discussed in further detail below, include an ignition device for igniting a combustion of a fuel/oxidizer mixture and a detonation chamber in which pressure wave fronts initiated by the combustion coalesce to produce a detonation wave. Each detonation or quasi-detonation may be initiated either by an external ignition source, such as a spark discharge, laser pulse, heat source, or plasma igniter, or by gas dynamic processes such as shock focusing, auto-ignition, or an existing detonation wave from another source (cross-fire ignition). The detonation chamber geometry may allow the pressure increase behind the detonation wave to drive the detonation wave and also to blow the combustion products themselves out an exhaust of the pulse detonation combustor. Other components and other configurations may be used herein.
- Various combustion chamber geometries may support detonation formation, including round chambers, tubes, resonating cavities, reflection regions, and annular chambers, Such combustion chamber designs may be of constant or varying cross-section, both in area and shape. Exemplary combustion chambers include cylindrical tubes and tubes having polygonal cross-sections, such as, for example, hexagonal tubes. As used herein, “downstream” refers to a direction of flow of at least one of the fuel or the oxidizer.
- Referring now to the drawings, in which like numbers refer to like elements throughout the several views,
FIG. 1 shows a generalized example of apulse detonation combustor 10 as may be described and used herein. Thepulse detonation combustor 10 may extend from anair inlet 15 and one ormore fuel inlets 20 at a head end to anexit nozzle 25 at an opposed downstream end. Acombustion tube 30 may extend from the head end to theexit nozzle 25 at the downstream end. Thecombustion tube 30 defines acombustion zone 35 therein. Other components and other configurations may be used herein for detonation and/or quasi-detonation. - The
air inlet 15 may be connected to a source of pressurized air such as a. compressor. The pressurized air may be used to flu and purge thecombustion zone 35 and also may serve as an oxidizer for the combustion of the fuel. Theair inlet 15 may be in communication with acenter body 40. Thecenter body 40 may extend towards thecombustion zone 35. Thecenter body 40 may have any size, shape, or configuration. Likewise, thefuel inlet 20 may be connected to a supply fuel that may be burned within thecombustion zone 35. The fuel may be injected into thecombustion zone 35 so as to mix with the airflow. - An
ignition device 45 may be positioned downstream of theair inlet 15 and thefuel inlet 20. Theignition device 45 may be connected to a. controller so as to operate theignition device 45 at desired times and sequences as well as providing feedbacks signals to monitor overall operations. As described above, any type ofignition device 45 may be used herein. The fuel and the air may be ignited by theignition device 45 into a combustion flow so as to produce the resultant detonation waves. Other components and other configurations may be used herein. Any type ofpulse detonation combustor 10 may be used herein. -
FIGS. 2 and 3 show a pulse detonationcombustor heat exchanger 100 as may be described herein. The pulse detonationcombustor heat exchanger 100 may include a number ofpulse detonation combustors 110 positioned therein. As described above, eachpulse detonation combustor 110 includes acombustion tube 120 that defines acombustion zone 130 therein. Eachpulse detonation combustor 110 also includes anair inlet 140, afuel inlet 150, and anigniter 160, Other components and other configurations may be used herein. The air and the fuel are ignited by theigniter 160 to create a. flow ofcombustion gases 170 within thecombustion zone 130 of eachcombustion tube 120. - The pulse detonation
combustion heat exchanger 100 includes anouter chamber 180. Thepulse detonation combustors 110 are positioned within theouter chamber 180, The pulse detonationcombustor heat exchanger 100 also includes one or moreinner pathways 190 extending through theouter chamber 180. The one or moreinner pathways 190 may be one ormore chambers 195, a series of tubes, and similar types of transport structures, Theinner pathway 190 may extend from acold inlet 200 to ahot outlet 210. Theinner pathway 190 may be positioned about a. pair ofheaders 220, Apreheater 230 also may be used about thecold inlet 200. Theinner pathway 190 may be positioned about thecombustion tubes 120 of thepulse detonation combustors 110. The positioning may be in a cross-flow orientation, a co-flow orientation, a counter-flow orientation, or any desired flow orientation. A workingmedium 240 may flow through theinner pathway 190. The workingmedium 240 may be any type of gas or liquid that absorbs heat therein. - In use, the
pulse detonation combustors 110 generate thehot combustion gases 170 within thecombustion zone 130 of eachcombustion tube 120. Likewise, the workingmedium 240 enters theouter chamber 180 via thecold inlet 200. The workingmedium 240 exchanges the heat with and is warmed by thecombustion gases 170. The now hot workingmedium 240 then passes through thehot outlet 210 for useful work in a turbine or other type of harvesting device. Thecombustion gases 170 also may be vented for use downstream for preheaters, super heaters, economizers, and the like. Theinner pathway 190 also may be used as a blockage device for heat transfer therewith. - The generation of the
combustion gases 170 thus increases the heat transfer rate from thecombustion tubes 120 to the workingmedium 240. The detonation conditions produce shock waves that scour away the protective layer of inactive gas or particles on the tube walls so as to increase the rate of heat transfer. The use of the pulse detonation combustors 1.10 also should reduce fouling of theinner pathway 190. Thepulse detonation combustors 110 also have less unburned fuel so as to reduce overall. emissions. -
FIGS. 4 and 5 show an alternative embodiment of the pulse detonationcombustor heat exchanger 100. In this example, a pulsedetonation combustor boiler 250 is shown. As above, the pulsedetonation combustor boiler 250 includes a number of thepulse detonation combustors 110. Eachpulse detonation combustor 110 includes thecombustion tube 120 so as to define thecombustion zone 130, Eachpulse detonation combustor 110 also includes theair inlet 140, thefuel inlet 150, and theigniter 160 so as to produce the flow ofcombustion gases 170. - The pulse
detonation combustor boiler 250 also includes a number ofboiler tubes 260 in communication with a pair ofheaders 270. Aneconomizer 280 or other type of heat exchanger may be positioned downstream of theboiler tubes 260. A number of thecombustion tubes 120 may be positioned in one direction with a further number of thecombustion tubes 120 positioned in an opposing direction. Theboiler tubes 260 may be positioned in a cross-flow orientation. Any type of flow orientation may be used herein. - In use, the
pulse detonation combustors 110 create the flow ofhot combustion gases 170 within thecombustion zone 130 of eachcombustion tube 120 about theboiler tubes 260 and theeconomizer 280 to downstream. Heat thus is exchanged with thecold working medium 240 from theeconomizer 280 through the connection tubes to thebottom water header 270 and then through theboiler tubes 260 to thetop steam header 270. The now hot workingmedium 240 or steam then may flow from thetop header 270 to the next station for useful work via a turbine or other type of harvesting device. Thecombustion gases 170 likewise may be vented for downstream use after theeconomizer 280. Other components and other configurations may be used herein. - It should be apparent that the foregoing relates only to certain embodiments of the present application and that numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
