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.

A dual gas turbine generator set is composed of two parallel gas turbines as the power source. The two gas turbines are connected to the overrunning clutch parallel mechanism through two laminated couplings, and the overrunning clutch parallel mechanism is connected to the generator through a laminated coupling. The core components such as the laminated coupling and generator between the parallel mechanism and the generator are placed in a container with sound insulation devices, forming the main engine compartment, The main equipment and sound insulation box in the main engine compartment are installed on the overall chassis of the unit. This utility model achieves the goal of improving the power generation efficiency and saving fuel by using a type of gas turbine with a higher rated power generation gas turbine generator set and selecting a single or dual gas turbine according to the user's electricity consumption situation. It is suitable for large and medium-sized telecommunications bureaus, large enterprises, institutions, hotels, and other cities at all levels Hotels and key departments can be widely promoted and applied as backup emergency power sources during power outages.
