75t/h流化床锅炉掺烧干气技术分析与改造

Technical analysis on mixing dry gas into coal for 75t/h fluidized-bed combustion boilers and their retrofit

流化床锅炉掺烧干气在国内只有个别厂家实施小比例掺烧,较大比例的掺烧技术尚无成功经验和先例。为了节约能源,更好地利用炼油厂气资源,对延安石化厂3台75t/h锅炉进行了技术改造,实现了较大比例的干气掺烧的技术应用。

In China,only very few plants implemented low proportion dry gas mixing into coal for burning in fluidized -bed combustion boilers,there is no successful experience and precedent in the high proportion mixing technology.To save energy and better utilize the dry gas resource of the oil refinery,the technical renovation to the three 75 t/h boilers in the thermodynamic plant of Yanan Petrochemical Plant was made,the technical application of high proportion dry gas mixing has been realized.
