Biomass for heat and power generation holds a large potential as renewable source of energy and for reducing greenhouse gas emission. However, this may result in altering the combustion conditions and ash behaviour, which could lead to an increase in slagging/fouling of the heat exchange surfaces. The objective of this study was to focus on the boiler performance monitoring in three large-scale demonstration plants in order to assess ash deposition, fouling, and burn-out under co-firing operating condition at different biomass shares. The results proved that the characterisation methodology can provide valuable information related to fouling and ash deposition monitoring in large-scale power plant boilers.
