ABSTRACT:
A combustible gas burner having simple, effective safety features. The burner head is made of ceramic to provide insulation between the flame and the gas inlet, thereby preventing autoignition. The ceramic head is formed with a multiplicity of passages therethrough, which are sufficiently small to function as a flame arrester. This multiple passage structure also functions to reduce flame-out when a lean combustible gas mixture is subject to external dilution air. The ceramic burner head is secured to the gas inlet opening by means of a bonding agent which expands as it cures, thereby providing a positive mounting.
