Novel system integrations of 1000 MW coal-fired power plant retrofitted with solar energy and CO2 capture system

Abstract The energy penalty of MEA based post-combustion CO2 capture technology will reduce the efficiency of coal-fired power generation significantly. The introduction of solar energy to the capture system can compensate the CO2 capture penalty. This paper proposed three integrations of 1000 MW coal-fired power plant retrofitted with solar energy and post-combustion CO2 capture system (PP + Solar + PCC), which the solar energy is used to replace the 1st extraction to heat the feedwater or provide the MEA regeneration heat demand is the main difference in three PP + Solar + PCC both in thermal and economic. The 1000 MW coal-fired power plant, solar aided coal-fired power system and coal-fired power plant with post-combustion CO2 capture system (PP + PCC) are selected as the reference cases. By comparison of six systems, it was concluded that the integration of using solar energy to replace the first high pressure extraction and taking a part of intermediate pressure cylinder exhaust to provide the reboiler heat demand is the best in three strategies of PP + Solar + PCC. In addition, this paper analyzed the evaluation indicators variation with the changes of CO2 removal rate, solar collector field area, DNI, solar collector field cost, coal cost and carbon tax.
