PERFORMANCE OF TWO DIFFERENT INCINERATION SYSTEMS FOR PAPER SLUDGE
A large amount of wastepaper is used to produce recycled paper in China and then generates the paper sludge and residues. Energy recovery by means of combustion in Waste-to-Energy (WTE) plants is considered to be a preferable approach to disposal paper sludge and residue. The technical and economic efficiency analysis of two different incineration systems, direct incineration system of partially dewatered sludge and dried sludge incineration system, was performed in this work. The results indicate that the dried paper sludge incineration method is a reasonable approach to reduce the consumption of co-fired coal, decrease the flue gas and air system load and flow rates and drop the operating costs compared with the partially dewatered paper sludge incineration method. The weight ratio of paper sludge and residue to auxiliary coal based on the entire WTE plant is much higher than the ratio based on the use of a CFB incinerator when using dried sludge incineration system. It is considered that the adoption of the weight ratio of paper sludge to coal based on the entire WTE plant is a more suitable managed resource utilization criteria.
