摘　　要：第一台220 t h水冷方形分离器循环流化床锅炉在山东威海热电厂投入商业运行已3年。最长连续运行时间已超过了5000 h。燃料适应性较好,并在污染物排放上满足了当地环保标准。介绍了该炉的运行性能,如带负荷能力、床温、床压降、主蒸汽参数等,表明该技术和该炉的设计是成功的。Three years have past since the first 220t/h circulating fluidized bed boiler with water cooled square shaped separators has been put into commercial operation at Shandong Weihai Cogeneration Power Plant. Several years of operational practice show that the boiler' s performance is good, with a maximal continuous operating time of over 5000 h. The boilers' outstanding superiority lies in its high reliability and its fuel flexibility. Its combustion efficiency is quite satisfactory, with emission of pollutants meeting local standard requirements. An account of the boiler's performance is being presented, e.g. load carrying capability, bed temperature, pressure drop of the furnace, fresh steam parameters as well as the state of fly ash, circulating ash and that of bottom ash, which demonstrate the success of its technology and design.
