Description
Summary: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 particle sizes on thermal efficiency of convective heating surfaces in boiler was analysed. Additionally, influence of fuel change at the nature of heat transfer in boiler, mainly at the flue gas temperature distribution and boiler efficiency, was also presented. The results may be used as a basis of experimental, in lab-scale as well as in technical-scale, research planning and of slagging and fouling prevention guidelines for boilers operators.
