Fuel burner

Abstract

A fuel burner for a fireplace is provided. The fuel burner comprises a tubular body forming a plenum extending between an open proximal end and a closed distal end. The body comprises a plurality of ports extending from the plenum to an exterior surface. The proximal end configured for threaded engagement with a pipe fitting enabling fuel flow into the plenum and through the ports to the exterior surface for combustion. The body is constructed from a single, continuous piece of material using an additive manufacturing process.
