Single-ended self-recuperated radiant tube annulus system

摘要

A method and apparatus for combustion of a fuel and oxidant in which at least a portion of a fuel and at least a portion of an oxidant are introduced into an annular region formed by an outer tubular member closed off at one end and an inner tubular member open at both ends concentrically disposed within the outer tubular member, forming a fuel/oxidant mixture. The fuel/oxidant mixture is ignited in the annular region, forming products of combustion therein. The products of combustion are then exhausted through the inner tubular member providing oxidant preheating prior to forming the fuel/oxidant mixture.
