Analysis of the high back pressure circulating water heating solution of 350MW supercritical air cooling unit

Abstract

Abstract:

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.
