浅析亚临界600 MW凝汽机组供热改造

Aanlysis of Heating Transformation of 600 MW Subcritical Condensing Unit

随着雾霾天气逐渐增多,中国对环保越来越重视,取消地方供热小锅炉,采用大型节能环保锅炉供热,已成必然趋势。热电联产是节能的重要途径之一,热电联产又以背压供热节能效果最为显著。目前小机组纯凝改背压的实例很多,但大型汽轮机供热改造涉及到的较少,通过对亚临界600 MW凝汽机组供热改造研究,对机组经济性安全性影响进行分析。

With the fog haze weather increased gradually, more and more attention was paid to environmental protection in our country. The small local heating boilers are canceled, while large energy conservation and environmental protection boiler heating are applied, which become an inevitable trend. Cogeneration is one of the most important ways of energy saving, another back pressure cogeneration heating is the most significant for saving energy. Now a lot of instances are the small unit pure condensation changing into back pressure while few reforming with the large unit pure condensation are discussed.By studying the heating transformation of 600 MW subcritical condensing unit, the influence on security and economy of the unit were analyzed.
