Co-firing of Brown Coal &Bagasse for Sulfur Reduction

Abstract

Biomassresources such as bagasse, sawdust, rice husk, wheat husk, coconut etc play the vital role in reducing the concentration of SOx and NOx gases when used in co-combustion mode. This study focused on characterization and emission analysis of coal and coal-biomass blends. The blends of brown coal with bagasse in weight proportion10%(CBg-1), 20%(CBg2), 30%(CBg-3)respectively were characterized by thermal techniques. Proximate and ultimate analysis of coal, bagasse and coal-bagasse blends was carried out. The study reveals that CBg-1 releases 4.18%, CBg-2 emits 3.65% and CBg-3 contained 2.87% of elemental sulfur. Muffle furnace flue gases analysis depicted that coal-bagasse blends samples CBg-1 releases CO NO 2 , 2, NO and SO 16.573%, 0.01435%, 0.008237%, 2 0.4384% respectively. It was concluded that sulfur contents were reduced by addition of biomass, SO and 2 x NO emissions were reduced, whereas CO emissions 2 were increased. Reduction inSO , NO and x x enhancement in CO showed efficient and 2 environmental friendly combustion
