Background
During the operation of the boiler, a very firm covering layer, namely coking, is easily formed on a boiler hearth, a flue and a water-cooled wall due to the combined action of the condensation of volatile ash components on the water-cooled wall and the heat transfer deposition of micro particles. The phenomenon of boiler coking is often unavoidable and can cause significant adverse effects on the safe operation and thermal efficiency of the boiler. After the water wall tube is coked, the heat exchange speed can be reduced, the water wall absorbs less heat, the heat loss of exhaust smoke is increased, and the treatment efficiency of the boiler is reduced. Meanwhile, coking can also cause the temperature of superheated steam to be higher, which causes the overtemperature of the pipe wall of the superheater and even the explosion of a steam-water pipe. In addition, the coking easily forms the lime-ash bold, can pound bad cold ash bucket water-cooling wall after dropping, makes dragveyer, slag crusher transportation difficulty simultaneously, causes the slag runner to plug up when serious, influences normal operating. In addition, the large coking pieces can cause unstable combustion and even flameout in the boiler after falling.
The mode of coking clearance mainly has two kinds, and one of them is, after the boiler stops the machine and cools off, maintainer gets into the boiler furnace and carries out the manual work and coke, and this kind of decoking mode intensity of labour is big, and maintainer carries out the operation in the boiler furnace, has certain safety risk. Secondly, when the boiler is operated, a maintainer pokes a slag poking pipe (made of steel pipes, reinforcing steel bars or flat irons and the like) inwards along a smoke pipe slowly by poking the slag poking pipe externally, and when resistance is met, the maintainer pokes the slag poking pipe inwards suddenly by applying force violently and then pulls out the slag poking pipe quickly, so that the operation is difficult, and high-temperature scalding is easy.
