Why the fuel of the coal-fired boiler needs to add water before entering the furnace?

16 Oct 2020

The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.

The purposes of adding water to the coal

1) Prevent waste. Adding water to the pulverized coal fines can prevent the fines from being blown away by the forced draft fan, which is good to let the coal fines stick together.

2) Improve combustion. Reduce the unevenness of the fire bed caused by uneven coal particles and improve the fuel combustibility.

3) Improve ignition. The coal is relatively dry, so the volatiles are difficult to separate out. It is appropriate to add water to improve ignition.
