Abstract

This study was investigated co-firing of biomass and coal for NOx reduction using 1 MW_th multi-burner furnace. NOx acts as a precursor of particulate matter formation and the minimization of its release from coal combustion has becomes an urgent issue. Three biomass types (wood pellet, torrefied biomass, and empty fruit bunch) were tested at different ratios through direct co-firing with coal and separate feeding as reburn fuel. It was found that the NOx reduction was achieved by up to 25% by direct co-firing and up to 50% by reburning. Although co-firing biomass as reburn fuel was more efficient for NOx reduction, further investigation is required for its applications in commercial plants.
