摘要
对超超临界机组几种典型供汽方案进行了研究分析,具体方案包括补汽阀供汽、气动引风机供汽、压力匹配器供汽、锅炉侧新蒸汽直供等多种形式。重点对抽汽方案、技术参数、经济性等问题进行了分析讨论,可为同类型机组供汽改造提供借鉴。
Several typical steam supply schemes for ultra-supercritical units were analyzed, including steam from supply valve, steam supply from pneumatic draft fan, steam supply from pressure adapter, new steam supply from boiler side, etc. The focus of the research is on the steam extraction schemes, technical parameters, economics and other issues, with a view to providing reference for the steam supply transformation of the same type of units.
