【Abstract】 [Objectives] The mechanism of the impact of carbon capture technology on the peaking capacity of coal-fired power plants was analyzed, and the impact of carbon capture technology on the power generation efficiency of coal-fired power plants was quantified. [Methods] A typical coal-fired power plant was used as an example, and a post-combustion carbon capture scheme was selected. The simulation model of the conventional coal-fired thermal power unit and the carbon capture power plant was constructed by ENSILON software.The operation interval of the carbon capture power plant was derived. A comparative analysis of the operation of a carbon capture power plant and a conventional coal-fired power plant was conducted, and the variation in the peaking performance of the units was investigated. [Results] The equivalent output power of the carbon capture power plant decreases by 1%-2%,the net output power decreases by 20%-30%, and the net efficiency of the whole field decreases by 8%-10%compared with that of the conventional coal-fired power plant. [Conclusions] The addition of a carbon capture system would allow the plant to gain greater downward peaking depth and faster peaking response while reducing efficiency.更多还原
