Abstract
As concerns regarding greenhouse gas emissions from coal-fired power plant increase, there is greater
focus on the feasibility of cofiring high ratios of biomass. This report first addresses the technical
issues which arise when cofiring biomass at high ratios in coal-fired power plant. These principally
concern the availability of fuel, storage and handling, milling, slagging, fouling, corrosion and ash
disposal. It then describes experience of power plant which have cofired high ratios of biomass over
extended periods. These plant are located mainly in the Netherlands and Denmark and a few in the
USA, Finland, Belgium and the UK. The report also briefly assesses issues arising when repowering a
coal-plant to fire 100% biomass.
