This work provides a practical engineering design on the new 600 MWe coal-fired power plant coupled with CaO-based carbon capture system. Three heating surface layout cases are proposed in order to realize the high temperature heat source of the new power plant to heat the feed water into the superheated steam (24.2 MPa, 566 °C). In addition, pipeline calculation and economic analysis for three cases are carried out. The results show that the heat exchange area of three cases increases, respectively by around 33.5%, 47.3% and 53.7% as comparing to the benchmark 600 MWe coal-fired power plant under the carbon capture efficiency of the coupled system is around 90%. In the pipeline design, the flue gas resistance of case 1 through heat exchange pipeline is about 0.74 MPa. The economic analysis shows that case 1 has a slight advantage as comparing to cases 2 and 3. The research provides a good direction for future research direction of the coal-fired power plant coupled with CaO-based carbon capture system.

这项工作为新的 600 MWe 燃煤电厂与 CaO 基碳捕获系统相结合提供了实用的工程设计。为实现新建电厂高温热源将给水加热成过热蒸汽（24.2 MPa，566 ℃），提出了三种受热面布置案例。此外，还对三种情况进行了管道计算和经济分析。结果表明，在耦合系统碳捕集效率在90%左右的情况下，与基准600 MWe燃煤电厂相比，三种情况下的换热面积分别增加了约33.5%、47.3%和53.7%。在管道设计中，案例1通过换热管道的烟气阻力约为0.74 MPa。
