ABSTRACT:
Liquid slag passes from an overflow in a pressure vessel into an underlying collecting vessel where the liquid slag is transformed into solid granular material by quenching in a liquid coolant. A desired coolant level is maintained within the collecting vessel by control valves under a pressure above atmospheric pressure. Two slide valves in the bottom of the collecting vessel are opened to discharge the granular material after accumulating to a predetermined measured level which is below the liquid coolant in the collecting vessel. A discharge vessel, beneath the collecting vessel, receives the discharged granular material. The discharge vessel is filled with a liquid coolant under either atmospheric pressure or under the same elevated pressure as the pressure within the collecting vessel. When the pressure in the discharge vessel is at atmospheric pressure, two slide valves in the bottom of the discharge vessel are opened to discharge the solid granular material into an underlying container which includes a scraper conveyor to transport the solid granular material.
