An energy utilization system composed of gas turbines and flue gas heat pumps, gas turbines, flue gas turbines and flue gas heat pumps, or gas turbines, waste heat boilers, steam heat pumps, as well as gas turbines, waste heat boilers, steam turbines, and steam (flue gas) heat pumps. After completing the energy utilization cycle of gas turbines, flue gas turbines, waste heat boilers, steam turbines, and other equipment, the system further utilizes heat pumps to deeply recover and utilize the waste heat from flue gas, steam, hot water, and cooling water, or directly drives the heat pump with power. This process can be used for cogeneration, thermoelectric cooling cogeneration, heat cooling cogeneration, electric cooling cogeneration, direct heating or direct cooling. The system has extremely high thermal efficiency, and if used for direct heating, the thermal efficiency can reach 150%, which is one of the main trends in future energy utilization.

Gas turbine power generation technology has been widely used in major thermal power plants in China. However, the maintenance issues that gas turbines must face during use are not optimistic. Due to the fact that the cleanliness level of natural gas may not be effectively controlled, impurities in natural gas can easily accumulate in the compressor chamber and even corrode the base metal. Many times, manufacturers must undergo a filtration process before introducing gas turbine combustion. Despite filtration, there is still accumulation of impurities and corrosion of the base metal in the compressor chamber. Therefore, the gas turbine must be cleaned regularly. Otherwise, the efficiency of the gas turbine will gradually decrease and affect its service life.
