Patent ID: 8236071

Claim:
A quench ring for use with a gasifier system, said quench ring comprising: an annular manifold having a radius sized to extend about a portion of a syngas flowpath defined within the gasifier system, said manifold oriented such that the syngas flowpath is substantially perpendicular to cooling fluid flow within said manifold; an annular channel coupled in flow communication to said annular manifold via a slit, said annular channel including an outer wall coupled to an outer edge of said slit, said annular channel extending radially inward from said annular manifold, wherein said outer wall includes an arcuate portion having an apex that is upstream of said slit outer edge with respect to the syngas flowpath; and a plurality of inlets coupled in flow communication with said manifold, each of said plurality of inlets having a center line aligned substantially with a tangent line of said quench ring, said plurality of inlets oriented in the same plane as said annular manifold, such that cooling fluid is discharged into said manifold in a direction that is substantially perpendicular to the syngas flowpath, said plurality of inlets coupled circumferentially around said annular manifold.
