Two Reasons Why Biomass Fired Boiler Leakage

As energy price is increasing and pollution is more and more serious, more enterprises seek green and environmental protection fuel, biomass as the ideal energy is to replace some fossil fuels to be used in industrial boilers.

A green biomass fired boiler is a high efficient and environment-friendly product that can easily burn shaped biomass fuel or both pure and mixed coal with its economizer in the rear. Fuel: Biomass fuel forming; rice husk, bagasse, coconut shell, straw, coal and biomass blends

Biomass fired boiler might occur leakage that affect its efficiency. Here are the Two Reasons Why Biomass Fired Boiler Leakage.

Oxygen corrosion
For the water tube biomass fired boiler pressure parts,the water side is mainly electrochemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 "industrial boiler water quality" requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.

Chlorine Corrosion
The chlorine ion exchange will cause high rate of metal corrosion,which is due to that the chloride ion radius is small,and it is typically activated anion,it is more active when the oxygen exists.With the operation of the boiler,if the boiler water salinity increases,the concentration of chloride ions rise constantly,there will be more deposits at the bottom of the boiler,in smoke pipe and the water cycle weak areas.
