摘要:

摘要:伊宁市位于新疆西部,地处严寒地区,随着城区的发展建设,供热面积逐年递增,分散小锅炉供热方式被热电联产集中供热方式代替乃大势所趋。国网能源伊犁煤电有限公司地处伊宁市,规划建设2×350MW热电联产机组及配套管网用于城市集中供热,采用高背压循环水供热节能技术, 运行方式为“一抽一背”。介绍了350 MW超临界空冷机组高背压循环水供热方案,分析了该方案的可行性,认为该方案可增加供热能力,能有效缓解伊宁市供热紧张局面。

Abstract:With the development of urban construction,the heating area of Yining city,where is located in the severe cold region of western Xinjiang,is increasing annually.Therefore,the scattered small boilers heating mode is replaced by the cogeneration district heating mode gradually.For urban district heating,Ili Coal and Electricity Company Limited.plans to construct two 350MW cogeneration units and corresponding pipe network,which adopt the energy saving technology of high back pressure circulating water heating.The two units are working in peak shaving mode,which means when one unit is working in high back pressure heating mode,the other one is in extraction condensing mode.This paper introduced the high back pressure circulating water heating solution of 350MW supercritical air cooling unit and analyzed its feasibility.It considered that the solution could increase the heating ability and relieve the heating tense situation of Yining.
