摘要
燃气蒸汽联合循环电站的余热锅炉,其系统布置、受热面结构、热力特性和运行工况等与常规锅炉比较有很大的差别,如汽水系统的优化,节点温差、接近点温差的选取,降低排烟温度和烟气侧压损系数的优化以及余热锅炉的变工况特性等都是需要考虑的关键性问题。文章介绍了燃气蒸汽联合循环余热锅炉的性能、型式及国内外发展概况。
Compared to normal boilers,the HRSG of Gas_steam Combined Cycle Plant is quite different in many aspects,such as system arrangement,heating side structure,thermodynamic characteristic and the working condition etc.So optimizing the steam_water system,selecting the point temperature difference and approach temperature difference,lowering waste smoke temperature,optimizing pressure coefficient and the characteristic are all the key issues to consider firstly.The performance,style and domestic and foreign development general situation of HRSG of gas_steam combined cycle are introduced in this paper,and the discussion is made on the research direction of HRSG.
