凌钢焦化初冷器余热回收供暖改造及分析

Transformation and Analysis of Heating with Waste Heat Recovery from Coking Primary Cooler in Lingyuan Steel

焦炉初冷器煤气冷却水水量大、温度高,蕴含巨大热能,对这部分热量进行回收,利用循环泵将冷却(供暖)水通过热力管网供至小区采暖泵房,实现余热供暖,为企业创效,为市民供热,具有显著的经济效益和社会效益。

The gas cooling water of the primary cooler of coke ovens has high flowrate and high temperature,which contains huge amount of heat energy.To recover this part of heat,the cooling(heating)water is delivered to the heating pump room of residential areas through heat pipe network by a circulating pump,realizing heat supply by waste heat,to create revenue for the enterprise and supply heating to the public with significant economic and social benefits.
