Abstract
A simplified submerged chain conveyor system for handling ash produced by large-scale coal fired boilers. The system incorporates an endless chain conveyor system moving a coal/ash aqueous mixture within a conveyor segment having a hydraulically closed duct. The system is adapted for retrofit applications of existing coal-fired boiler installations. In each embodiment the chain conveyor elevates the aqueous ash solution to dewater the ash. In several embodiments the boiler ash hopper is partially flooded with water and the system moves the ash mixture through a water column to the dewatering section. In one embodiment the ash mixture is not submersed but is subjected to water sprays before reaching the dewatering section. Great flexibility is provided in locating and positioning the conveyor system. One unit may be implemented to provide ash handling for multiple boilers. Embodiments are described operable in continuous or batch mode processes.
