Low-carbon efficient hydrogen / ammonia doped natural gas power generation system

Abstract

The invention belongs to the technical field of natural gas power generation, and discloses a low-carbon efficient hydrogen / ammonia doped natural gas power generation system which comprises a gas turbine cycle power generation system and a waste heat utilization system. Natural gas is mixed with hydrogen or ammonia gas in a certain proportion to serve as an energy source, CO2 emission of a power generation system is effectively reduced, the hydrogen / ammonia energy utilization rate is increased, and the method has great significance in promoting energy structure transformation. The natural gas hydrogen / ammonia doping technology and the carbon capture technology are coupled, on one hand, carbon elements in fuel are reduced, and the content of CO2 in flue gas is reduced; on the other hand, low-concentration CO2 gas in the flue gas can be captured, carbon emission of a power generation system can be further reduced, and the dual-carbon target can be achieved. The hydrogen / ammonia-doped natural gas is coupled with a waste heat utilization technology. The temperature of the discharged flue gas is increased along with the increase of the hydrogen / ammonia doping amount, and the waste heat power generation potential is increased. The waste heat utilization technology makes full use of heat energy in smoke and converts the heat energy into electric energy, so that the efficiency of the power generation system is improved.
