The temperature of the combustion gas in the combustion chamber of the Stirling engine can drive the piston to circulate continuously, thereby driving the generator to generate electricity;

[0009] A battery, the battery is electrically connected to the generator, and the battery is used to store the electric energy generated by the generator;

[0010] A thermal energy device is used to collect and utilize the thermal energy generated by the combustion of the combustion gas.

[0011] Furthermore, the thermal energy device includes a water tank and a hot water pipe connected to the water tank, the hot water pipe is connected to the heat source of the Stirling machine, the hot water pipe is connected to a heat-conducting aluminum block, and the heat-conducting aluminum block can melt snow using heat.

[0012] Furthermore, the Stirling engine also includes a cold chamber, which is used to dissipate heat for the combustion chamber. Water is arranged in the cold chamber, and the cold chamber is connected to the water tank through the hot water pipe to realize water circulation and dissipate heat.

[0013] Furthermore, the system also includes a power generation control system, which is used to monitor and adjust the operating status of the generator to ensure its stable and safe operation.

[0014] Compared with the prior art, the energy system based on the natural gas Stirling generator provided by the present application realizes the use of natural gas to generate electricity through the Stirling motor, and stores the generated electricity through batteries. At the same time, the heat generated during the combustion of the combustible gas in the Stirling machine is also utilized.
