Background art:
the power demand is common to human life and production, and the conversion of heat energy formed by fuel combustion into mechanical energy is an important way for obtaining and providing power; high temperature heat loads are efficiently converted to mechanical energy, requiring reasonable thermodynamic cycle equipment and settings.
Fuel is an important option for constructing high-temperature heat sources, and has different types and different properties; wherein the temperature of the fuel gas formed by the combustion of the fuel directly determines the heat power conversion efficiency.
