The structure solves the problems of heavy tar pipe blockage in the process of connecting volatiles to the furnace of an incinerator by pyrolysis / gasification; deflagration and local overheating in the furnace caused by uneven condensation of volatiles entering the furnace of an incinerator; and tempering at the interface in the process of connecting post-volatiles to the furnace of an incinerator.

A combustion chamber with a trapped vortex micro-mixing combination nozzle, the combustion chamber includes a nozzle body, a flame tube and a combustion chamber casing; wherein the nozzle body is arranged at the head of the combustion chamber, and is connected with the flame tube and is arranged together in the combustion chamber casing; the internal cylindrical area formed by the flame tube is the combustion zone of the combustion chamber, and the flame tube and the combustion chamber casing form a compressed air flow cavity. Compared with the traditional combustion chamber, the nozzle body of the present invention adopts the staged combustion technology, and takes into account the technical advantages of the micro-mixing burner and the trapped vortex burner. On the basis of ensuring stable combustion under low working conditions, it effectively reduces pollutant emissions under high working conditions, thereby broadening the stable operation range of the gas turbine combustion chamber.

This invention proposes a hydrogen fuel turbine engine, including an air intake, a compressor, a hydrogen combustion chamber, a turbine, an exhaust nozzle, and a hydrogen storage device. The hydrogen combustion chamber is supplied with hydrogen via a hydrogen supply pipe, which is installed in an air supply pipe to form an air supply unit. The hydrogen storage device is connected to the hydrogen supply pipe. The air compressed by the compressor enters the hydrogen combustion chamber and is split into two paths. One path directly enters the interior of the flame tube through air holes on the flame tube wall, while the other path is split into multiple paths and connected to the air pipe. The air supply unit enters from the rear end of the flame tube and extends to the front of the flame tube. The hydrogen supply pipe and the air pipe respectively spray hydrogen and air towards the head of the flame tube, where air and hydrogen are mixed and combusted at constant pressure in the flame tube. This invention incorporates an air pipe outside the hydrogen supply pipe. On one hand, this introduces more gas, which lowers the temperature of the main combustion zone in the combustion chamber and reduces the generation of nitrogen oxides. On the other hand, the air pipe can also serve as a heat insulation pipe, effectively reducing the surface temperature of the hydrogen supply pipe. Simultaneously, the air inside the pipe impacts the flame tube head, which not only lowers the temperature of the head panel but also generates a complex vortex structure at the flame tube head, further enhancing the mixing of hydrogen and air. The inconsistent natural frequencies of the vortices prevent thermal oscillation problems.
