With the domestic circulating fluidized bed(CFB)boiler being larger,the cold test is becoming more and more important in the commissioning and operation of the large CFB boiler.The CFB boiler can safely and steadily run based on the correct result of the cold test.The problems and key-points during the cold test of the first owning Chinese intellectual property right 1 025 t/h CFB boiler was analyzed and summarized.Here the cold test was mainly composed of air flow meter calibration test,air distribution plate characteristics test,material resistance and the critical wind mass test,air distribution symmetrical characteristics test in furnace and air distribution plate resistance characteristics test outside bed.The method and advice from practical experience and theoretical design can provide reference for the unit steadily running,commissioning and operation of the large CFB boiler.
