燃烧后CO2捕获与燃气–蒸汽联合循环机组热力能源整合研究
Study on the Thermal Energy Integration of Post-combustion CO2 Capture in Natural Gas Combined Cycle Plant
摘要
Abstract
A 350MW?h natural gas combined cycle-combined heat and power (NGCC-CHP) plant in Beijing was the research object. An integrated model of NGCC plant and 90% post-combustion CO2 capture was built. Based on the thermodynamic analysis of integration interface, this work evaluated three options for providing the energy necessary for the amine reboiler. The results show that: when the NGCC plant was integrated with full-scale PCC and compression, the efficiency of the power plant deceases from 56.21% to 47.28%; the heat recovered from multistage intercooler can reduce the district heating steam extraction by 7.02 t/h in CHP mode; supplementary firing improves the steam turbine power output up to 135.84MW?h with 50.2% of net equivalent efficiency, while have a good economic performance.关键词
