城市热电联产机组供热能力和余热利用分析

Analysis of Heat Supply Capacity and Waste Heat Utilization of Urban Cogeneration Units

介绍了郑州市热电联产机组供热现状和基于吸收式换热的余热利用新技术,并对集中供热热源供热能力进行了统计和分析。发现通过纯凝机组的供热改造和余热回收,热电联产的供热能力将达到5 613 MW,供热面积为1.2亿m^2,热电联产将满足远期郑州城市供热增长的需求,可以实现城市清洁供热。

The present situation of heat supply for Zhengzhou cogeneration unit and the new technology of waste heat utilization based on absorption heat transfer are introduced. It is found that through the heat supply transformation and waste heat recovery of the pure coagulation unit, the heat supply capacity of cogeneration will reach 5 613 MW and the heating area will be 120 million m^2. The cogeneration will meet the long-term growing demand of Zhengzhou's urban heat supply and realize urban clean heating.
