超临界二氧化碳火力发电系统模拟研究
Simulation study on supercritical carbon dioxide thermal power system
摘要
Abstract
The Aspen plus software was applied to establish the mathematical model for supercritical carbon dioxide brayton cycle and the thermal power system of a 600 MW unit was calculated.The effects of several factors such as compression split coefficient,turbine split coefficient,pressure ratio of the compressor,inlet temperature of the turbine and main compressor on the system cycle efficiency were analyzed.The results show that,the compression split coefficient,the pressure ratio of the compressor,the inlet temperature of the turbine and main compressor have remarkable effects on the system cycle efficiency,while the turbine split coefficient has little effect.There exists an optimal coupling value between the pressure ratio of the compressor and the compression split coefficient,which results in the highest circulation efficiency.The system circulation efficiency increases with the inlet temperature of the turbine but decreases with the rising inlet temperature of the main compressor.关键词
