摘　　要：根据某410t/hCFB锅炉实际运行情况和测试结果,制定了冷渣器流化风系统优化改造方案,并进行了分析设计,使冷渣器流化风直接取自锅炉的一次风系统,并将原冷渣器流化风机停止备用,从而减小了运行电耗,并降低了设备维护费用。运行结果表明,改造后节电效果显著,系统运行稳定。The paper presents an updating scheme for ash cooler fluidized air system of a 410t/h CFB boiler.The ash cooler fluidized air,which is originally designed,is provided by the independent configuration of two forced fans.By analyzing and studying the operating data of the primary air and the ash cooler fluidizing air system at various operating conditions,an optimum scheme is put up that fluidizing air of the two ash coolers is provided by its cold primary air system,instead of the two independent high-pressure fans.Therefore the boiler electric power consumption rate is decreased.The result of the updating for ash cooler fluidizing air system is satisfied.
