Abstract
The engineering system model of coal based supercritical carbon dioxide brayton cycle splite-flow recompression normal system, two reheating system and multistage compression system were established with aspen plus. The effects of the same compression split coefficient, the inlet pressure of reheating turbine, the inlet and outlet pressure of the compressor, the inlet temperature of the main compressor, the inlet temperature of the high pressure turbine and reheating turbine on the system cycle efficiency and effectiveness of heat exchanger were analyzed and comparison based on the 600MW thermal power system. In general, the effect of the compression split coefficient, the inlet and outlet pressure of the compressor and the inlet temperature of the main compressor on the system cycle efficiency and effectiveness of heat exchanger are significant, and the effect of other factions are not obvious. The performance of the two reheating system is better than the normal system and multi-stage compression system, and the multi-stage compression system does not effectively improve the system efficiency.
