【Abstract】 The technology for sludge dried and blended with coal to combust utilizes the existing coal-fired boiler to recover the waste heat of the boiler for sludge drying. Dried sludge is blended with coal to combust for heating or power generation,thereby realizing reduction,harmless and resourceful use of sludge. This paper expounds the potential advantages of sludge blended with coal combustion.Through comprehensive analysis and comparison of sludge blended with coal combustion technologies,it is considered that it is a feasible combustion method to carry out dry sludge blended with coal combustion in circulating fluidized bed boiler. The principle of sludge drying is discussed,and feasible waste heat drying methods for circulating fluidized bed boiler is proposed. The combustion characteristics of sludge were also discussed,and the influence of dry sludge blended with coal combustion on the operating conditions of circulating fluidized bed boiler was analyzed.更多还原
