Claims

[Scope of Claim for Utility Model Registration] (1) A right cylindrical combustion cylinder to which combustion air is supplied from the rear end has a large diameter toward the tip and a gas injection hole at the small diameter rear end. A hollow truncated cone-shaped flame stabilizing plate is formed and has a plurality of secondary air ejection holes scattered therein, and its large diameter front end is positioned slightly toward the rear end from the tip of the combustion tube. Along with letting
A secondary air jet flow path is formed between the combustion cylinder inner circumferential surface and the gas jet hole of the flame stabilizing plate is provided with a gas inlet for introducing a partially premixed gas consisting of gas fuel and primary air. The pipe is connected, and a guide member is provided near the small-diameter rear end of the flame holding plate in the space of the flame holding plate to guide a part of the premixed gas from the gas introduction pipe along the inner circumferential surface of the flame holding plate. A gas burner characterized in that it is provided with: (2) The gas burner according to claim 1, wherein the guide member is made of a porous material in which a large number of fine holes are formed through the flame stabilizing plate in the axial direction. (3) The gas burner according to claim 2, wherein the guide member has a shielding plate at the center thereof. (4) The gas burner according to claim 1, wherein the guide member is formed in a flat plate shape with a space between it and the inner circumferential surface of the flame stabilizing member.
