塔式太阳能辅助1000MW燃煤发电机组锅炉的热力性能分析
Thermal Analysis on the Boiler Performance of 1000MW Tower Solar Aided Power Generation Unit
摘要
Abstract
A tower solar energy aided coal-fired generation system was proposed by integrating a 1000MW ultra supercritical unit.A part of high temperature steam extracted from after the platen super heater was sent to the tower solar receiver.In order to balance heating surface energy matching and ensure safe operation,a flue gas recirculation system was installed.Simulation software Ebsilon professional for power station was chosen to simulate thermodynamic performance.The results show that the flue gas recirculation system can decrease levelized cost of energy (LCOE) of the hybrid generation system.The boiler efficiency during off-design operation doesn't drop significantly.The different loads of the hybrid generation system are analyzed.The maximal coal consumption rate can be reduced about 7.2g/(kW·h) compared with a 1000MW conventional fossil-fuel fired power plant.It is indicated that the hybrid generation system has higher thermal-electric efficiency.关键词
