An ash disposal system for ash discharged from a coal-fired combustion chamber

摘要

Apparatus for handling ash produced in the combustion of coal in the furnace (10) of a steam generator, including an ash hopper (14) beneath the furnace (10), a water transport system (26) for carrying the ash away from the hopper (14), a screen arrangement (32) for separating most of the water from the ash, and a relatively small settling bin (40) or tank for separating the ash from the remainder of the water. The separated water can be recycled in a closed loop (44), to be used again as the transport water.
