富磷添加剂对生物质燃烧中积灰结渣和腐蚀作用的探析
Study on the effect of phosphorus rich additives on ash deposition, slag and corrosion during biomass combustion
摘要
Abstract
In this paper, it was discussed the reaction mechanism and effects of phosphorus rich additives on ash deposition, slagging and corrosion on the boiler heating surface during combustion of biomass. Besides, the main influencing factors such as combustion temperature, atmosphere, biomass species, Ca/K mole ratio, P/K molar ratio were investigated. The results show that alkali metals (mainly potassium) and chlorine in flue gas were fixed in the bottom ash by the phosphorus rich additives,producing high-melting point compounds, which alleviated molten-slagging induced by alkali metal and chlorine corrosion. In addition, the additive changed the physical properties and chemical properties of ash, making it soft and not easy to sinter. Therefore, the ash deposition, slagging and corrosion during combustion of biomass were effectively relieved.关键词
