Emissions of CO, SO 2 and NO x were measured and combustion efficiency was determined. Fly ashes and bed material were characterized in terms of mineralogical, chemical and morphological analyses and the slagging/fouling and agglomeration propensities were obtained. Control methodologies for mitigating ash problems were applied, using innovative mineral additives during combustion. The results indicated that when co-combusting lignite and olive tree prunnings SO 2 and NO x emissions were reduced, as compared to combustion of lignite. Combustion of each fuel alone could provoke medium or high deposition problems. However, blending of the fuels resulted in lower deposition and corrosion problems in boilers firing this mixture. The use of fuel additives decreased the concentration of alkali in the fly ash and enriched bottom ash in calcium compounds. http://creativecommons.org/licenses/by/4.0/International Nordic Bioenergy Conference
