Based on the acceleration of the urbanization process in China, the municipal sludge production is greatly increased, and the recycling and energy utilization of the sludge are one of the directions for disposing the sludge. The incineration disposal of the coupling sludge of the coal-fired power plant is a safer treatment mode, can be reduced to a greater extent, and can ensure the standard emission of the incineration by utilizing the ultra-low emission environmental protection facility of the coal-fired power plant. In contrast, Shanghai City has issued "emission standards of atmospheric pollutants for coal-fired coupled sludge power plants (DB 31/1291-2021)" to be implemented from 2021 month, which provides a basis for sludge coupled blending combustion rate and emission reaching the standard after combustion.

The coal-fired coupled sludge blending combustion is divided into direct blending combustion and drying-after-blending combustion, and the blending combustion is carried out when the sludge with the water content of more than 80% is dried until the water content is lower than 40%; and for the semi-dry sludge with the water content of 40-60%, direct blending combustion coupling can be carried out according to actual conditions. Generally, sludge in municipal or paper mills and the like is transported to a coal-fired power plant through a closed special vehicle and then is unloaded to a special sludge unloading hopper in a coal field area or a near boiler area in the plant, and an unloading grid is arranged above the sludge unloading hopper, so that the falling sludge is uniformly distributed, larger rods and stones in the sludge are blocked, and downstream sludge transporting equipment is prevented from being damaged by smashing.

For semi-dry sludge with the water content of 40% -60%, the sludge is in a clay shape due to low water content, has no fluidity, but has high viscosity, is easy to agglomerate and fall, causes large-area blockage of a discharge grid above a sludge discharge hopper, and influences sludge discharge.
