The Use of Waste Biomass from the Wood Industry and Municipal Sources for Energy Production

Biomass can be used for the production of energy from renewable sources. Because of social resistance to burning crop plants, mixtures and pellets made from or including waste materials are a good alternative. The mixtures analyzed, prepared from wood and municipal waste, were characterized for their calorific values, 7.4-18.2 MJkg(-1). A result, over 15 MJkg(-1) was obtained for 47% of the quantities of mixtures being composed. It has been demonstrated that wood shavings and sewage sludge have a stabilizing effect on the durability of pellets. The emissions of acidic anhydrides into the atmosphere from the combustion of pellets from waste biomass were lower for NO, NO2, NOx and H2S than emissions from the combustion of willow pellets. Obtained emission results suggest the need to further optimize the combustion process parameters.
