高温高压锅炉在干熄焦工程中的应用

Application of high temperature and high pressure boiler in CDQ project

结合以往对各种干熄焦锅炉的标定数据以及在干熄焦锅炉选择过程中存在的制约因素,对干熄焦装置的生产能力、工程投资及企业现状等因素进行对比分析,为干熄焦锅炉炉型的选择提供了建议。同时针对高温高压自然循环干熄焦热力系统和中温中压联合循环干熄焦热力系统,在节能方面、锅炉效率、钢材消耗、系统电力消耗、发电量的差异以及锅炉的开工与运行方面的差异进行了对比分析,进而了解两种参数的热力系统在各方面的优缺点。

In combination with the rating data for various kinds of CDQ boilers and constraint factor existed in selection process of CDQ boiler,the factors such as productivity of CDQ,project investment and enterprise present situation were compared and analyzed,which has provided a suggestion for selection of boiler type for CDQ project.At the same time,against high temperature and high pressure natural circulation CDQ thermal system and medium temperature and medium pressure combined circulation CDQ thermal system,the difference of energy-saving,boiler efficiency,steel consumption,system electric power consumption,power generation capacity as well as the difference between boiler start-up and running were compared and analyzed,every advantage and disadvantage of thermal systems of two parameters were understood furthermore.
