Description

technical field [0001] The invention relates to the technical field of CFB circulating fluidized bed boilers, in particular to a method for detecting coal breaking of CFB circulating fluidized bed boilers which can quickly and accurately detect coal breaking faults of CFB circulating fluidized bed boilers. Background technique [0002] Under the dual pressure of energy and environment, circulating fluidized bed (CFB) boilers have developed rapidly in my country due to their remarkable characteristics such as strong fuel adaptability, high combustion efficiency, good load regulation performance, and low pollutant emissions. As of the end of 2011, according to incomplete statistics, there are more than 3,000 circulating fluidized bed boilers of different capacities in my country, and more than 90,000 MW have been put into commercial operation. More than 40 300MW circulating fluidized bed boiler units have been put into operation, and more than 110 300MW circulating fluidized b...
