Description

Technical Field

[0001] The utility model relates to the technical field of smoke and air systems, in particular to a dust cleaning device for a standby boiler flue. Background Art

[0002] The boiler tail flue refers to the flue installed at the tail of the boiler for exhausting smoke. Air leakage in the boiler tail flue usually comes from two parts: one part is due to the flue being in a negative pressure state, leaking in from the loose sealing of the outer wall of the flue; the other part is leaking in through the air preheater tube or the loose partition of the smoke and air system. Air leakage in the boiler tail flue affects the economy of boiler operation and the safe operation of downstream desulfurization equipment. To control air leakage in the boiler tail flue, corresponding countermeasures must be taken according to different leakage locations and different causes of air leakage.
