Air heater cleaning We utilize high-pressure water jets to clean the boiler dust generated during operation. After cleaning the air preheater, the partial pressure difference of the boiler reaches the required operating standards.，Air Preheater The flue gas in the boiler tail smoke channel is preheated to a certain temperature by the internal fins to the heating surface before entering the boiler, which is a device used to improve the heat exchange performance of the boiler and reduce energy consumption.Equipment with high consumption rates.Coal-fired power plant boilers

Available in two types: tube box and rotary, with the rotary type further divided into wind-shielded rotary and heating surface rotary. Power plant boilers commonly use heating surface rotary preheaters. Their application in boilers is typically in two-chamber, three-chamber, or four-chamber configurations, with the four-chamber being more commonly used in circulating fluidized bed boilers.Chinese。Physical cleaning method brings significant economic benefits to boiler cleaning:

One: Reduce cleaning costs.

Reduced wastewater treatment fees.

Three, the increased production benefits from continuous cleaning without shutdown are quite remarkable.

Four, the cleaning process continuously improved the boiler's thermal efficiency and saved fuel; these streams of water, one after another, possess immense impact energy. Physical cleaning with this method can cut steel plates, remove sand from castings, and rust from metals, and can also remove salts, alkalis, scale, and various obstructions from the inside of pipes. Cleaning using this highly energetic stream of water is known as high-pressure water jet cleaning.

(2) Classified by physical properties, there are two types: scale that is firmly adhered to the pot shell and tube walls, and sediment that is loosely textured and easy to dislodge.
Lime scale primarily forms due to the salts like calcium and magnesium in the boiler feed water, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of lime scale is very low, around 2 to 5 times that of ordinary steel. Lime scale deposited on the boiler's heating surface significantly worsens heat transfer efficiency and affects the boiler's performance; it can easily cause metal materials to burn due to local overheating, even leading to pipe explosion accidents; it also accelerates galvanic corrosion, causing pipeline lime scale corrosion and speeding up the damage to the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
