First, let's take a look at what is boiler ash and slagging. Boiler ash and slagging refers to the large amount of tiny ash particles generated during fuel combustion in the process of flowing with the flue gas stream. Due to the surface tension of the ash particles, the viscous force between the particles and the inner wall of the furnace, The effects of molecular adhesion, electrostatic attraction, and chemical affinity are accumulated in the heat transfer surfaces of the boiler wall and the flue. Fuel composition, boiler load and combustion conditions, and boiler burners all have an impact on the ash build-up of the boiler.

Boiler ash and slagging is a common problem and has a great impact on the economics of boiler operation. The accumulation of ash on the heating surface of the heating furnace not only affects the heat transfer efficiency of the heated surface, but also causes the efficiency of the furnace to decrease. Moreover, due to the improper ash removal measures or the limitations of the ash removal technology itself, the ash accumulation on the heating surface of the heating furnace is increasingly intensified, affecting the heating furnace. Stable operation in the later period. When the ash and slagging in the heated area are serious, it may also cause accidental shutdown and cause significant economic losses. Therefore, the heating surface of the boiler must be regularly scanned and blown, and the boiler soot blower is an effective method to eliminate dust accumulation and ash blocking.
