马钢炼焦总厂北区干熄焦热管换热器的清洗实践

Abstract

Abstract:

The condition of CDQ tubular heat exchanger that dust is deposited on the external surface of the tube and fouling is formed inside the tube would impact convectional heating system,which will lead to low heat exchanging efficiency and failure in reaching the required quenching temperature.The cleaning of the CDQ tubular heat exchanger will have reduction of circulating gas pressure at outlet of the CDQ fan,increase of heat exchanging efficiency and CDQ capacity as well as longer service life of CDQ equipment.

Key words: CDQ, Tubular heat exchanger, , Heat exchanging efficiency

CLC Number:

TQ520.5
