Flame stabilized post-mixed burner

摘要

A burner and method enabling operation of a post-mixed burner having radially spaced fuel and main oxidant injection points with a stable flame without the need of a separate oxidant annulus proximate the fuel stream characterized by defined relationships enabling passing stabilizing oxidant from the main oxidant stream into the fuel stream upstream of their injection into the combustion zone wherein the stabilizing oxidant velocity decreases from that of the main oxidant and the stabilizing oxidant passage flow area increases at the fuel stream communication with respect to an upstream restriction.
