摘  要:目前煤粉室燃烧锅炉大都采用了节油点火装置,可节约大量燃油。但对于循环流化床(CFB)锅炉,由于其自身的特性,不适合采用节油点火装置。从安全性和经济性角度出发,通过对UG-480/13.7-M型CFB锅炉在内蒙古华宁热电有限公司1号锅炉调试过程中的点火问题进行分析,提出了一些节油方案:将床下大油枪改为小油枪;根据一次风机电流与床层差压之间的关系实现安全的微流化点火;确定合适的启动床料量;确定合适的投煤温度,获得了较理想的节油效果。According to the energy, saving policy of China, now most of the coal fired boiler apply the oil saving technique, but the CFB boiler can' t apply it for its characteristics. Considering the security and economic effect, by analyzing the firing problem in the commissioning process of the UG-480/13.7-M CFB boiler in Baotou Cogeneration Power Plant No. 1, some ways are given to save oil for the CFB boiler, including reducing the capability of oil gun, firing on the light fluidizing state according to the relationship of PAF' s electric current and bed differential pressure, finding the suited temperature of feeded coal, confirming suited start-up bed material flow and so on. The project practice shows that the ways give an excellent result of saving oil.
