摘要/Abstract

摘要：

干熄焦热管换热器外管积灰、内管结垢后，影响对流给热系数，导致热管换热效率低下，熄焦温度达不到生产要求。通过清洗干熄焦热管换热器，降低了风机出口气体压力，提升了换热器换热效率，提高了干熄焦生产能力，延长了设备使用寿命。

关键词: 干熄焦, 热管换热器, 换热效率

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
