A large amount of heat energy generated by the combustion of the fuel in the combustion chamber is absorbed by the combustion chamber walls, resulting in a large amount of heat energy loss. 3. The temperature of the whole injector is increased after the combustion chamber wall absorbs heat, and the interlayer water jacket must be made to be cooled and protected so as to facilitate personnel operation and environmental temperature, and a large amount of water resource consumption is caused despite the water recycling. 4. The high-temperature high-speed hot air flow combusted by the combustion chamber is sprayed out from the flame spraying port to generate larger Xiao Sheng which is about 120 dB, so that the sound wave propagation pollution is caused, and the method is very unfavorable for operators and surrounding environments.
