Abstract:
In light of issues frequently occurred to the circulating fluidized bed boilers within the plant, such as water-cooling wall leakage, coal plugging in the boiler, and large particle size of the coal fed into the furnace, a specialized technical research group was set up in Henan longyu Chemical Co. ,Ltd. to analyze the reasons behind such issues. Through water- cooling wall modification, feed coal quality control, process operation optimization, new type boiler water treatment agent utilization and development of the long-cycle reward system, the device operating quality has been significantly improved, realizing such remarkable result as 373-day Grade A continuous stable operation of boilers.
