Abstract

This paper mainly discusses the effects and reaction mechanism of Al and Si additives on corrosion related to ash deposition to heating surface in biomass-fired boiler, analyzes the main factors af-fecting the effect of additives, and discusses the best proportion of Si and Al in additives. The re-sults show that Al and Si in additives react with alkali metal and chlorine in combustion to produce compounds with high melting point, reduce the content of corrosive components in ash, and inhibit the corrosion during biomass combustion. When the Si/Al in the additive is 1, or the Ca:A1:Si mo-lar ratio is 1:2:1, the additive has the best effect.
