ABSTRACT

Due to the content of alkaline compounds, biomass combustion inflicts unfavourable effects on boilers, such as: corrosion, slagging, and fouling of the bed. One of the methods to limit these processes is adding sulphur to the boiler. This article presents the results of studies on the impact of adding sulphur into the boiler (where biomass is combusted), and on the properties of the formed fly ash and bottom ash. As a result, sulphur compounds were mainly in fly ash, which makes it impossible to utilize it in the manner that coal fly ash is normally used.
