碳捕集技术应用对燃煤机组调峰能力的影响
Effect of Carbon Capture Technology Application on Peak Shaving Capacity of Coal-Fired Units
摘要
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.关键词
