| 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. |
