Investigation of ash deposition in PF boiler during combustion of torrefied biomass

The paper presents an analysis concerning the propensity of torrefied biomass to slagging and fouling and impact of its combustion on heat exchange in existing pulverized fuel boiler in reference to Polish coal. The impact of torrefaction on slagging properties was also investigated. Based on the results of ash composition and fusibility analyses the most common ash deposition indices were determined. The effect of ash composition and its...
