Abstract [en]

Increasing the sulphur content in the fuel by has been used in boilers fired with biomass in order to prevent high temperature corrosion. The higher sulphur content can be achieved by mixing with high sulphur fuels, e.g. coal or peat or by adding of various sulphur containing chemicals. An additional effect of increasing the sulphur content is that in some cases the emissions of soot, carbon monoxide (CO) and hydrocarbons have been shown to decrease. This has lead to an increasing interest in using sulphur addition as a method to reduce these emissions in medium sized grate boilers fired with biomass fuels, that for different reasons have problems to reach the legislated limits e.g. for CO emissions. However, there have also been a few reports suggesting that the emissions of fine particles in the submicrometer size range might increase with sulphur addition (Lindau and Skog, 2003). Since medium sized grate boilers often lack efficient devises for fine particle removal, there has been a concern that the positive effects on CO emissions by sulphur addition might be accompanied by enhanced particle emissions. In this study CO and particle emissions from a 7 MW boiler fired with moist forest residues with varying admixtures of elemental sulphur were characterised.
