The development and application of circulating fluidized bed boiler technology has been widely used. The technology is one of clean coal combustion and advanced technology for realizing sustainable development. It integrates the advantages of energy saving, clean combustion, safety, reliability, pollution emission reduction and the like. However, in actual operation of the boiler, some local structural problems may also affect the efficiency of the boiler. For example, due to frequent blockage of a slag discharge port, slag discharge of the boiler is gradually abnormal, and safe and economic operation of the boiler is seriously influenced.
At present, the dredging mode of the ash (slag) discharging port of the circulating fluidized bed boiler is mainly to facilitate dredging when blocking slag by additionally arranging a slag poking inclined pipe on a valve or a slag dropping pipe. Once the ash (slag) discharge port is blocked, the conventional dredging mode is that a organiser inserts the slag poking strip from the slag poking inclined tube to the ash (slag) discharge port of the boiler to poke slag manually, and the labor intensity of on-site operators is high. Because the hearth of the circulating fluidized bed boiler is slightly positive pressure, the high-temperature ash residues leak risk when the slag is poked, scalding accidents are easy to cause, and great potential safety hazards exist. Meanwhile, when dredging is carried out through the slag poking inclined tube, if the adopted angle is not proper, the slag poking strip acts on the wear-resistant castable at the ash (slag) discharging port of the boiler, so that the risk of falling off of the wear-resistant castable of the hearth can be increased. And the time required from the task of poking the slag to the completion of dredging the dust (slag) discharging port by the organization personnel on site is long.
If the ash valve at the ash (slag) discharging port or the slag dropping pipe is not additionally provided with the slag poking inclined pipe, once the ash (slag) discharging port is blocked, the dredging is carried out after the furnace is stopped.
