摘　　要：研究分析了330MW亚临界汽轮机大流量工业供汽改造的技术方案,对比分析了常规冷热再抽汽供热、增设小背压机供热、级间抽汽供热及中排供热等方案,最终选取了增设级间三段抽汽供热结合汽轮机通流改造的方案,该方案具有较高经济性和安全性,可以为同类型机组提供参考借鉴。Researched and analyzed the technical solutions of 330MW subcritical steam turbine large-flow industrial steam supply retrofit,compared and analyzed the cold and hot re-extraction steam supply,add small back pressure steam turbine to supply steam,inter-stage extraction steam supply and medium pressure cylinder exhaust steam spply,etc.Finally,the option of adding a three-stage inter-stage extraction steam supply combined with a steam turbine flow passage retrofit plan was selected.This plan has high economy and safety,and can provide reference for the same type of units.
