摘要
大型火力发电厂是城市集中供热的主要热源之一。充分利用电厂乏汽余热,对节能减排和环境保护具有重要的的作用。针对火力发电厂间接空冷机组,提出了3种余热直接利用方案和2种余热间接利用方案。结合每种供热方式的特点和机组现有外部条件,最终提出5种可靠的供热方案及比选流程,对火力发电厂间接空冷系统余热供热改造具有一定的指导作用。
Large thermal power plant is one of the main heat sources of urban centralized heating.Making full use of the waste heat of the power plant is very important to emission reduction,energy conservation and environmental protection.Three direct utilization schemes of waste heat and two indirect utilization schemes of waste heat are proposed for indirect air cooling units of thermal power plants.Combining with the characteristics of each type of heating mode and units existing external condition,this paper finally puts forward to 5 kinds of heating schemes and reliable choosing process which is the guide line for waste heat utilization transformation of indirect air cooling system in thermal power plants.
