摘要:

结合宝钢干熄焦给水预热器的安装,详细介绍了新装预热器时换热器的选择和循环系统压力的调节等关键点的设计,采用偏心热管换热器,可以有效解决系统的换热、磨损等问题。通过安装给水预热器,有效降低了干熄炉进口循环气体的温度,干熄炉处理能力可提高5%以上,风料比降低50~100m3/t焦。

Abstract:

In combination with the installation of the CDQ water supply preheater of Baosteel, when preheater is installed newly, the designs of the key points, such as the selection of heat exchanger and the pressure regulation of circulation system are described in detail. The use of eccentric heat-pipe exchanger can solve the problems of the effective heat exchange of the system and wear of the system etc. Through the installation of water supply preheater, the circulating gas temperature at the inlet of CDQ chamber is lowered effectively, the coke treating capacity of CDQ chamber can be raised by over 5% and the ratio of air and coke is reduced by 50~100m3/t of coke.
