OSTI ID:6562762
Ash removal equipment associated with pulverized coal furnaces for large-capacity steam generators is disclosed. The equipment has a chain conveyor disposed beneath the combustion chamber of the furnace immersed in water and a protective hood preventing entry of outside air to the combustion chamber with hinged flaps by which the ash outlet of the combustion chamber can be closed off. With the coal furnace out of operation, the ash removal equipment can be elevated so that the hinged flaps are immersed in the water and can be lowered or raised during operation of the coal furnace relative to the position of the ash outlet.
