Abstract

A burner head is constructed with adjacent gas delivery tubes of different geometric cross-section shapes which are mechanically held in place radially. The tubes touch in a longitudinal direction at points along their respective inner and outer circumferences so that precise axial alignment whether coaxial or axially offset, is achieved while preserving the necessary laminar gas flow. This configuration greatly speeds the production time which allows economical burners to be produced even when a greater number of faceplate jets is desired. The tube-to-tube contact is also beneficial to the operation of the burner by providing a heat transfer path away from the innermost tube, which prevents overheating. Examples of the simplest geometric tube shapes employed are, for example, a square within a circle, or conversely, a circle within a square.
