循环流化床锅炉主要是针对劣质煤而设计的,适应矸石、低挥发分的煤种。同时,由于具有低温燃烧的特点,抑制了氮氧化物的生成,同时在燃料中添加石灰石等,可以在炉内脱硫。基于以上特点,这种锅炉主要建于坑口电站。但是由于炉内循环流化燃烧,对锅炉内部磨损比较严重,还有因为低温燃烧对燃烧不好控制,这两点一直是制约这种锅炉发展的瓶颈。近几年来,兖州矿业(集团)有限责任公司针对各煤矸石
Circulating fluidized bed boiler is mainly designed for low-grade coal, to adapt to waste rock, low volatile coal. At the same time, due to the characteristics of low temperature combustion, the formation of nitrogen oxides is suppressed, and limestone is added to the fuel for desulfurization in the furnace. Based on the above characteristics, this boiler is mainly built in Hang Hau Power Station. However, due to circulating fluidized combustion in the furnace, the interior of the boiler is more worn, and because of the poor control of the combustion caused by the low-temperature combustion, these two points have always been the bottleneck restricting the development of such a boiler. In recent years, Yanzhou Mining (Group) Co., Ltd. for each gangue
