摘要

电站锅炉的排烟热损失最大。当燃用中、高硫燃料

为防止尾部热面发生低温腐蚀和堵灰

一般都装设暖风器

从而进一步增加排烟热损失;随着单台锅炉容量的增大

该项热损失的绝对值也越来越大。所以

在能源紧张的今天

有效回收锅炉排烟余热刻不容缓。本文介绍了利用热管换热器回收锅炉排烟余热加热热系统的凝结水或加热冷空气

从而可较大幅度的降低排烟温度

提高电厂经济性、节约能源。同时也可有效的防止尾部热面低温腐蚀和堵灰。

Abstract

This paper presents a hot pipe heat exchange system which is used to heat the condensate of regeneratine system or cold air by recovered heat from boiler flue gas. With this system being used the temperature of flue gas can be greatly reduced

the efficienev inproved and energy saved. In the meanwhile low temperature corrosion and ash blockage in the back-end surfaces of boieer can be prevented.
