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.
