Research Status of Coal and Sewage Sludge Blending Combustion in Power Plant

YUE Jun-feng;ZOU Lei;ZHANG En-xian;Jiangsu Frontier Electric Technology Co., Ltd.;  
This manuscript reviews the research status of sewage sludge blending combustion in coal fired power plant. The processes of the sewage sludge blending combustion in pulverized coal fired boiler and circulating fluidized boiler were firstly introduced. Then, the effect of blending combustion on the igniting behavior, burnout characteristics and the emission properties of NOx and SO2 were discussed. The deposition and emanation characteristics of the elements in the blending fuel, especially the damaging elements such as As and Cr, were summarized. The economy efficiencies of the sewage sludge blending combustion in coal fired plant and drying and incineration technology of sewage sludge were compared. Taken together, sewage sludge blending combustion in coal fired power plant is one of the most effective technologies that can achieve the comprehensive utilization of sewage sludge. The coal pulverizing system needs some optimization adjustments to adapt the new fuels that make up by sewage sludge and coal.
