The effects of particle size, fuel blending ratio, moisture content and excess air ratio on combustion efficiency and air emissions (CO 2 , CO, SO 2 and NO x ) from the co‐combustion of white pine or peat with a Canadian lignite coal, were examined in a pilot‐scale bubbling fluidised bed combustor. Pelletising was important for the efficient combustion of wood due to its high volatile content. Co‐firing lignite and pine pellets gave a proportional reduction in SO 2 and NO x emissions with blending ratio, while co‐firing of peat and lignite resulted in increased SO 2 emissions, but decreased NO x emissions. Moisture promotes combustion but with increased CO emissions, and results in increased NO x emissions, and decreased SO 2 emissions. High excess air decreased CO, but moderately increased SO 2 and NO x emissions. © 2011 Canadian Society for Chemical Engineering
