During the actual operation of the boiler of the coal-fired power plant, the dust accumulation on the heating surface at the tail part is a common inevitable phenomenon. When the ash accumulation on the heating surface is serious, the heat transfer efficiency of a superheater, a reheater, an economizer and an air preheater is reduced, the exhaust gas temperature of a boiler is increased, the efficiency of the boiler is reduced, the overheating of the heating surface is caused, the corrosion of the heating surface is aggravated, the service life of the heating surface is shortened, the normal operation of the boiler is seriously influenced, and even the personal safety of inspection personnel is influenced. Therefore, ash deposition is a difficult problem in the operation of the coal-fired power plant boiler, and a proper soot blower must be arranged in the design and operation of the boiler.
The rotary air preheater is a low-temperature heating surface located in a flue at the tail of the boiler, and has the advantages of compact structure, steel and field saving, convenient installation and arrangement and the like, so that the rotary air preheater is widely applied to boilers of large-scale power stations. However, due to the structural particularity of the boiler, ash deposition is easy to occur, excessive ash deposition causes heat transfer deterioration and resistance increase, and a heating surface is blocked when the heat transfer deterioration is serious, so that the output of the boiler is reduced, and even a boiler shutdown accident is caused.
In the steam soot blowing technology, due to the characteristics of the structure and the medium, the soot blowing gun barrel is easy to generate phenomena of jam, failure, steam leakage and the like, high-quality steam is consumed, the moisture of flue gas is increased and the like; acetylene is used in the gas shock wave soot blower, so that the operation cost is high, certain dangerousness is realized, and phenomena of misfiring, tempering and carbon deposition can also exist in the operation process; the sound wave soot blower has poor soot blowing effect due to insufficient energy, and can basically not remove the existing accumulated soot.
