Background art:
people often need to utilize high-temperature heat energy to realize refrigeration, heat supply or power conversion, and also need to utilize power to refrigerate or utilize power and combine low-temperature heat energy to supply heat. In the process of achieving the above purpose, the energy is often limited by many factors, and people need to adopt advanced technical means to realize the efficient utilization of energy.
Fuel is an important option for constructing a high-temperature heat source, and has different types and different properties; wherein the temperature of the fuel gas formed by the combustion of the fuel directly determines the performance index of the heat pump device.
