Pollutants reduction in small biomass combustion systems (PRIBIC)

Contruction of a computing models that allow to understand the physical and chemical processes occuring in the combustor and its behaviour under deifferent operation conditions. In particular, a amodel to predict the NOx formation in the combuster will be also developed, and it will be integrated in the whole process simulation system. - Running, validation and reliability improvement of the whole computing simulation system with experimental combustion laboratory results. - Design, utilizing the above mentioned computing tools, of a second generation of biomass combustors with at least 30% emissions reductions of NOx and CO. Significant decreases in hydrocarbons and PAH's emission values are also envisaged in regard to those of first generation combustors presently existing in the market. The combustion efficiency of the new burners generation will be around 90%. - Construction and start-up of a 160 kW boiler of second generation, with the new design modification incorporated according the especifications given in the above point. - Evaluation of the new combuster as a multifuel equipment by operating it with ten biomasses with different particle size, heating value and humidity contents. Verification of the expected efficiency and reduced emission values with the selected biomasses. - development of a prototype of the new biomass combustion system for commercial use.
