COMBUSTION OF PITCOAL-WOOD BIOMASS BRICHETTES IN A BOILER TEST FACILITY

Abstract

The use of composite fuels using pitcoal and sawdust represents a high perspective.The paper deals with the experimental results focusing on the combustion efficiency of composite fuel briquettes and on the polluting emissions level.A special care is given to the determination of boiler efficiency and to the establishment of exploiting economic conditions, like the supply, cleaning etc.The research of the combustion of pitcoal-wood biomass briquettes is conducted on a 55 kW boiler.A numerical modeling of the combustion processes within the boiler allowed a critical comparison between the experimental and numerical data.
