Biomass is the largest renewable energy source. Currently, direct burning of biomass for heat and power generation is the most common and cost-effective routine to turn biomass into energy, in which suspension-firing is most widely used. Biomass requires much more care in handling than coal, particularly for suspension-firing which has the highest requirement on fuel quality and fuel particle size among all combustion technologies. This paper reviews the development of biomass preparation for suspension-firing, which directly affects fuel particle sizes and thus particle flow, particle burnout and ash usability. Another critical issue in biomass suspension-firing, i.e., deposition and corrosion, is also presented. All the discussion is combined with concrete examples of biomass dust-firing in power plants and their pros and cons, facilitating the understanding of the key issues and also providing good models or references for other biomass dust-fired power plants.
