Abstract
A process and apparatus, wherein as hot gas from a coal gasifier discharges through a tubular outlet having therein a wall which is permeable throughout its length for the flow of hot gas centrally therethrough, a gas shield is formed along the inner surface of the tubular outlet by passing a coolant through the wall, which gas shield cools the wall and prevents sticky ash particles in the hot gas from hitting the wall. The gas shield also cools the hot gas so that the sticky ash particles lose their stickiness.
