Abstract In order to investigate the pollutant emission status of Tianjin's domestic biomass pellet heating furnaces and provide scientific support for the governments'policy formulation,this study investigated the effect of the briquette fuel type and the furnace capacity on the pollutant emissions in Tianjin.The result showed that:rice straw contains more ash residues and less sulfur content than cotton straw,causing more smog and CO emissions,and less SO₂ emission.The emission amounts of CO and SO₂ increased,and that of NO_x decreased with the increasing of the feed rate during the cotton straw combustion in the same furnace.The major components of volatile organic compounds (VOC) emission,during the combustion process of these two briquette fuels,were ketones,benzenes,and aldehydes.The average emission values of NO_x,CO,SO₂,smog were 672.70,2297.94,124.00,109.35mg/m³,respectively.It is necessary to reduce the pollution emission of domestic biomass heating furnaces by adding water-bath duster device,adjusting the supply air rate to match the feed rate,and maintaining an appropriately excessive coefficient.Appropriate standards and policies are also needed to control of the quality of the domestic biomass heating furnaces and briquette biomass fuels.
