METHOD OF COOLING HOT GAS PRODUCT |
摘要 |
A process is disclosed for quenching of the partial combustion product gas of a slagging coal gasifier containing suspended molten slag particles wherein the hot product gas of the gasifier is passed through a tubular quench zone into which a shielding gas is introduced circumferentially to form an annular layer or protective gas shield between the product gas and the walls of the quench zone and a cooling gas is injected radially to effect direct cooling of the product gas to a temperature at which the molten slag particles solidify and lose their stickiness, said protective gas shield being maintained for a sufficient distance along the axis of the quench zone to prevent contact between the quench zone walls and the hot product gas during said cooling. |
