Abstract

The invention belongs to the technical field of compound energy power generation, and particularly relates to a gas-steam combined cycle combined power generation system integrated with a solid oxide fuel cell. The system comprises a gas compressor, a combustion chamber, a gas turbine and the solid oxide fuel cell, the gas compressor is sequentially connected to the combustion chamber and the gas turbine, the solid oxide fuel cell is connected to a post-combustion chamber, the combined power generation system further comprises a first waste heat boiler and a second waste heat boiler, the post-combustion chamber is sequentially connected to a fuel conveying unit and an air conveying unit and then communicates with the first waste heat boiler. An outlet of the first waste heat boiler is connected to an inlet of the second waste heat boiler. An inlet of the second waste heat boiler is further connected to an outlet of the gas turbine. The combined power generation system is provided with the two stages of waste heat boilers, exhaust gas of the solid oxide fuel cell and exhaust smoke of the gas turbine are fed into the first waste heat boiler and the second waste heat boiler respectively according to the principle of gradient utilization of energy, and the energy utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of composite energy power generation, and in particular relates to a gas-steam combined cycle composite power generation system integrating solid oxide fuel cells. Background technique [0002] my country's power structure is dominated by coal power, and the coal-fired power generation system causes CO 2 Emissions remain high. With the continuous development of electric power production, the combustion of coal fuels leads to increasing air pollution and greenhouse effect, which seriously threatens the natural environment on which human beings depend for survival. In recent years, carbon dioxide emissions have grown rapidly, and the coal consumption of coal-fired power plants accounts for about half of the country's coal consumption. Therefore, for a long period of time, adjusting the energy structure and promoting the development of low-carbon fuels is undoubtedly the key to CO2 emissions. 2 The subject of ...
