  ABSTRACT: A combined system of heating, power and biogas (CHPB) system has been developed and tested in a single building in MinQin County, Gansu Province, China. The proposed system satisfies the user’s demand of power, heat, and gas. The CHPB system can effectively overcome seasonal, climate and many other factors which affect the production of the renewable energy. For this purpose, experiments were conducted extensively during the winter period from November 2014 to March 2015. Compared with conventional energy supply systems meets the test household indoor temperature level, the system can reduce the consumption of standard coal 5819.30 kg/year, and save energy costs 11,046.20 yuan/year, the system’s payback period of 4.37 years, also can save 27.03 tons of carbon dioxide emissions. As a result, the CHPB system have been successfully tested for single building, use solar energy and biomass as input and produce power, heat, and gas steadily. These results contributed to the construction of energy supply systems.
