Abstract

The invention discloses a combined heating and power system of a heat source complementary Stirling engine as well as a method of the system. A disc-type secondary reflector is used for focusing solar light onto a hybrid heat source heater; the hybrid heat source heater is connected with a heat end of the Stirling engine, and an output end of the Stirling engine is connected with a generator; a cold water tank, a water pump, one path of a cooler of the Stirling engine and a smoke gas side heat exchanger in the hybrid heat source hater are sequentially connected with a hot water tank; the other path of the cooler of the Stirling engine is directly connected with the hot water tank; a fuel compensating device and an electric control valve are sequentially connected with a heat source heater; and the output end of the Stirling engine, a data acquiring and detecting device, an auxiliary heat source controller and the electric control valve are sequentially connected. According to the combined heating and power system, problems of instable electric output, poor durability and difficult grid connection of the conventional solar generating system; meanwhile, the system realizes combined heating and power; and competitiveness of a solar heat generating grid and entire economic benefit of the system are greatly improved.

Description

technical field [0001] The invention relates to a heat source complementary Stirling engine cogeneration system and its method, in particular to a Stirling engine cogeneration system and method driven by solar energy and auxiliary heat source complementation. Background technique [0002] Solar energy is the most abundant renewable clean energy on the earth. Under the background of the current global energy crisis, it has become an inevitable trend of human development to develop renewable energy such as solar energy to replace traditional fossil energy. However, due to the low energy density and poor stability of solar energy, and the influence of geographical distribution, seasonal changes, and alternation of day and night, its power supply is very unstable. Once this renewable energy is developed and connected to the grid on a large scale, the unstable power supply will pose a great threat and burden to the safe and stable operation of the domestic large grid. The proble...
