The size and density of the inner combustion chamber surface holes are determined according to the material heat conductivity coefficient of the inner combustion chamber 9 so as to more accurately and effectively realize stable flameless combustion and achieve NO X For the purpose of lowering. When the heat conductivity coefficient of the internal combustion chamber 9 is relatively smaller, the internal temperature of the internal combustion chamber 9 is high, and holes are needed to be arranged on the surface of the internal combustion chamber 9 for heat dissipation and temperature reduction.
