Alternative fuels - agricultural waste materials utilization

The article is concerned with energy production from the heat-processed selected agricultural wastes. It means the possibility to use the wastes, solid biomass, alternative and standardized firings as the fuels for heat power plants. Within this experimental project, seventeen analyses of selected mixed wastes from agricultural production were carried out. The wastes are mostly formed into the pellets. These are then analysed in details in order to find out the chemical and stoichiometric composition and energy balance. Mixed and pelleted fuels from the agricultural wastes have a different structure and parameters. It mostly results from the different concentrations of element compositions in waste mixtures. Some negative characteristics of water and ash matter content follow from the elemental analysis and stoichiometric calculations. From the view of emission concentrations, the amounts of sulphur, nitrogen and chlorine in wastes are the most important parameters. Solving of this up-to-date problem contributes to emission reduction and in this way also to air pollution reduction.
