Coal injection system to rotary kiln

coal injection in rotary kiln k.ramu . Home ... The REI combustion simulation tool BANFF was used to model a coal and waste-fired cement kiln with various tertiary air injection systems to determine the best design for mixing waste combustion products. Studies showed the best designs used high velocity jets emanating from the center of the kiln

    GB2109100A - Rotary kiln coal gasifier with tar injection

    A method and apparatus is disclosed for reducing entrainment of fines of feed stock material in tar- laden gases produced by a rotary kiln in the gasification of coal or other carbonaceous material. The fines and tar are both separated from the gas and from each other. The separated fines are recycled by admixing and churning such fines with newly provided solid carbonaceous feed material and
