摘　　要：炉内喷钙脱硫是一种公认的经济适用的脱硫方法 ,对其在实施过程中对锅炉运行特性 ,如炉内结渣、受热面沾污、传热、受热面磨损、炉内燃烧工况、汽温、电除尘器、锅炉效率等进行了分析 ,并对其可能产生的环境问题进行了论述。Desulfuration through spraying calcium into the furnace is a generally recognized economic and suitable desulfuration method, the influences of the said method upon operating performance of the boiler in the process of its implementation, such as slagging in the furnace, heat surface contamination, abrasion of the heat transfer surface, combustion condition in the furnace, temperature of steam, effectiveness of electrical precipitator, and efficiency of the boiler etc., have been analyzed, and the environmental problems that may be occurred due to implementing the said method being discussed. It is found that the availability ratio of the said desulfuration facilities to be basically identical with that of the boiler equipment.
