Biomass combustion in small-scale boilers Eastern Europe has recently become a very popular heating option. are gradually replacing old, coal-fired installations, especially the domestic sector. In comparison with coal, biomass contains more phosphorus, chlorine, and potassium, which may cause corrosion, slagging, fouling of surfaces inside chamber. Such problems be reduced by properly controlling process, as well adding substances like halloysite to fuel. This paper presents results wood pellets made coniferous wood, rape straw, wood/rape blend process 25 kW retort boiler. The demonstrate that increases ash sintering temperature, may, turn, reduce slagging. addition also reduces KCl concentration total solid compounds, potentially lowering risk corrosion A slight reduction CO, OGC, SO2 concentrations was observed for straw addition. Moreover, experimental indicate fuel influence boiler efficiency, during agricultural its blends.
