Description
Technical field
The invention belongs to and adopt with the power engine of hydrogen with relevant gas fuel combination, particularly hydrogen blended gas fuel engine.
Background technique
Traditional combustion power machine complicated in mechanical structure, mechanical counterpart precision prescribed is high, and lubrication system is complicated.The whole control procedure of combustion power machine is very complicated, and mechanical loss is large, and mechanical efficiency is low.And behind the use hydrogen fuel, pure hydrogen power engine output power is low, and optimization fuel and mixing can make control procedure more complicated, require higher, there is significant limitation in the hydrogen fuel power machine of research at present, pre-ignition or abnormal combustion occur in the course of the work, causes power stage lower or unstable, lack practicability, and be difficult to promote.
Summary of the invention
The object of the present invention is to provide a kind of hydrogen blended gas fuel engine, simplified mechanical structure, it is rational in infrastructure, and control procedure is fairly simple, fuel combustion is stable, can put forward high-octane conversion efficiency, power stage is stable, and hydrogen usage is few, output power is high, mechanical assembly is few, and is easy to maintenance, need not to adopt complicated lubrication system.
The object of the present invention is achieved like this: a kind of hydrogen blended gas fuel engine, comprise the turbine rotor group, by casing, impeller shaft and impeller consist of, the jet ingress uniform at machine box-shrouded impeller outer peripheral surface arranging respectively corresponding ejecting gun, the spray gun port of ejecting gun is corresponding with impeller blade, ejecting gun is by the master, the gentle conductance of subsidiary combustion chamber consists of to gun barrel, rear wall in axiolitic subsidiary combustion chamber is arranging hydrogen nozzle and the igniter that the hydrogen gas pipe connects, the front portion of subsidiary combustion chamber is connecting the longitudinal end entrance that inwall is axiolitic main combustion chamber by collapsible tube, the outlet of the main combustion chamber major axis the other end is connecting and is being arc line shaped air-flow guiding gun barrel, guiding gun barrel end is arranging spray gun port, outlet locular wall at main combustion chamber is arranging the compressed-air atomizer that compressed air inlet pipe connects, and the vaporization gas nozzle of high-temperature evaporation gas steam inlet pipe connection is being set at the locular wall of main combustion chamber.
The present invention promotes the vane rotary acting by the high-temperature high-pressure air flow that A gas injection lance sprays.Its working procedure is: first pressurized air is passed in the main combustion chamber, be filled with the compressed-air actuated while to subsidiary combustion chamber, pressurized air also flows to the guiding gun barrel, after pressurized air impacts muzzle, spray into impeller blade and casing by mechanical seal and the formed static air pressure sealing of pressurized gas, form a relatively complete relative seal space, make the increased pressure of subsidiary combustion chamber, also in gun barrel, form simultaneously the vent plug that density is very high.This moment, hydrogen was injected into subsidiary combustion chamber, when ever-increasing hydrogen and pressurized air mix, lighted by igniter and produce detonation, mixed gas is in the process of subsidiary combustion chamber reaction, temperature and pressure is also constantly increasing, and spread to the muzzle direction, at this moment in main combustion chamber, spray into the water vapor of high-temperature evaporation, the water vapor that is in the thermolysis transition point is further vaporized by high temperature in main combustion chamber and is decomposited hydrogen and oxygen, further mix, burning, chemical reaction process repeatedly discharges higher temperature and pressure, and high-energy fluid impacts muzzle and promotes vane rotary.After impeller turns over a tooth phase angle when the second tooth position, just entered between the relative sealing merit of next acting, carrying out above-mentioned hydrogen and pressurized air mixes, igniter is lighted detonation, and high-temperature water vapor decomposes in main combustion chamber, mixes, the process of burning, the active force of detonation γ-ray emission continuously promotes follow-up blade impeller is continuously worked continuously.Waste gas is discharged from relief opening, participates in the process of producing of high-temperature water vapor or enters steam generating system.Hydrogen is to split water into hydrogen and oxygen by hydrogen generator, sends in the different ejecting guns by distributor after the hydrogen pump pressurization through the hydrogen after cooling.High-temperature water vapor sprays into ejecting gun by the rear vaporization of high-pressure service pump pressurization.
Key problem in technology of the present invention is that mixed gas forms certain first pressing in sufficiently long gun barrel, ignite the source by the hydrogen of seldom measuring as High Temperature High Pressure, and through repeatedly reacting the vent plug that is in a single day formed high pressure high density by supercharging repeatedly, will produce larger impulse force to load.Although the chemical reaction that in ejecting gun, occurs close to etc. appearance compression add adiabatic expansion, but the rear end is because length and the formed vent plug of pressurized air of gun barrel, the last ejecting gun outlet pressure of its process remains approximate isopiestic process, but right-about has occured in its energy properties, this mainly is that pressurized air has not only produced mixing of first pressing and hydrogen, improved the burning energy of hydrogen, also reduce simultaneously reacting dose and the rapid diffusion of hydrogen, the more important thing is the density that has increased mixed gas in the gun barrel.
The present invention has simplified mechanical structure, and it is rational in infrastructure, and control procedure is fairly simple, and fuel combustion is stable, improved the conversion efficiency of energy, power stage is stable, and hydrogen usage is few, and output power is high, mechanical assembly is few, and is easy to maintenance, need not to adopt complicated lubrication system.
