ABSTRACT:
A slag trap structure is for use where synthesis gas is generated having small particulate slag entrained therewith. It has a high pressure shell with a body of water at the bottom for quenching and removing the slag. There is a coaxial inner wall to direct the flow of synthesis gas and slag down from an inlet at the top toward the body of water. And there is an outlet spaced substantially above the level of the water to cause reversal of the gas and slag flow. Also, there is means for recirculating some clean gas in conjunction with the inner wall to direct a swirling flow that confines the downward flow centrally in the vessel.
