Particulate and gaseous emissions were studied in a 7 MW moving-grate boiler fired with moist sawmill residues together varying admixtures of elementary sulfur. The particle number concentration decreased by approximately 25% the sub-micrometer mass increased 100% as 0.17% (by mass, dry substance) sulfur was added to fuel. Sulfur addition also resulted shift towards larger mean diameters. Elementary analysis indicated that amount particle-bound significantly addition, probably favoring formation alkali sulfates. CO reduced 50% measurement period when admixture fuel or higher. SO2 measured downstream from flue gas condenser below detection limit no admixed 30 ppm 0.12% admixed. had significant effect on NOx concentration.
