SLAG REMOVAL SYSTEM Russian patent published in 2014 - IPC C04B5/02 F27D15/02 

FIELD: process engineering.

SUBSTANCE: invention relates to equipment used at production of combustible gas in furnace for gasification and fusion of gasified material. Proposed system comprises device for fast cooling of slag discharged from the furnace in liquid coolant to produce glassy slag. It comprises also the slag and coolant collector, pulp containing vessel to receive the slag from slag settling vessel in water to obtain slag-bearing pulp. Besides, it includes slag collector and device to feed slag from slag settling vessel into pulp bearing vessel. It has pulp pipeline to communicate pulp containing vessel with slag collector to suck slag bearing pulp from appropriate vessel into slag collector. It incorporates slag suction nozzle of diameter d arranged at pulp line inlet with clearance 0.25d-10d from pulp vessel bottom surface. Slag collector is equipped with water filter to separate slag-bearing pulp at pulp line outlet into slag and pulp.

EFFECT: stable and reliable process.
