Characterization of fine particulate matter generated in a large woody biomass-firing circulating fluid bed boiler

Abstract The formation and emission of ash particles in biomass combustion is one of the most intractable challenges in the biomass-firing utility boilers. In present study, field measurements of PM10 at the inlets and outlets of the baghouse equipped on a 50 MW biomass-firing CFB boiler were carried out. The results showed that PM10 generated from the combustion of the biomass fuels in the CFB boiler exhibited a uni-modal size distribution. The sole modal peak (appeared at 5 μm) in the PSD curve was located in the size range >1 μm, while there was no visible peak in the size range
