A Study on Fluidized Bed Sludge Combustion Technology and Analysis of Environmental Impacts

On the basis of analysing the various methods for the disposal of sludge, such as agricultural land filling, throwing into sea and burning in revolving kilns,the authors have come up with a new type of sludge heterospecific-gravity based fluidized bed combustion technology with emphasis on the analysis of sludge energy utilization. An experimental investigation is performed of the sludge caking and ignitioncharacteristics when burned in the fluidizecl bed. Also analysed and tested are the emissions of SO2, NOx, fluorine, chlorine and heavy metals following the combustion of sludge, which show that the sludge combustion in the fluidized bed is technically feasible and the emissions of POllutants are within the limits demanded by environmental protection requirements with no risk of secondary pollution arising there from. One can therefore conclude the above-mentioned technology can be advantageously applied for the disposal of sludge.
