ABSTRACT:
A gasifier for producing a usable gas by combusting a particulated carbonaceous fuel in a combustion chamber which is communicated to a cooling zone. A dip tube conducts an effluent flow of gas and slag to the bath by way of an upright guide passage. A segmented quench ring communicated with a pressurized source of a liquid coolant such as water, directs a flow thereof against the dip tube guide surfaces to maintain the latter in a wetted condition. The respective segments of the manifolded quench ring are supported in a manner to cooperate with each other, yet to maintain lateral interspacing therebetween. A shield disposed across the interspace permits the latter to adjust in response to thermal expansion and contraction of the respective ring or manifold segments.
