Micro gas burner

Abstract

Provides a micro gas burner with a stable, premixed flame that produces little or no soot or unburned hydrocarbons. A gas burner includes a fuel inlet, a nozzle, an oxidation chamber with at least one air inlet, a mixing chamber with a frusto-conical inner wall, at least one penetrable barrier, and a flame stabilizer. Gas burners thoroughly mix fuel and entrained air to form a nearly stoichiometric mixture prior to combustion. Gas burners thoroughly mix fuel and air, making them require lower fuel flow velocities than are required to produce a stable, premixed flame. Gas burners include optional flame tubes in which the flame is contained and isolated from diffusing air.

Description

technical field [0001] The present invention generally relates to a gas burner. In particular, the present invention relates to an integral gas burner for smoking articles that burn by premixed gaseous fuel. Background technique [0002] Small gas burners, such as those used in cigarette lighters, are well known in the art. Most cigarette lighters use buoyancy in order to carry air for spreading the combustion. Fuel gas and air meet at the ignition point and burn simultaneously. Therefore, in such lighters, fuel and air are not mixed upstream of the point of ignition. Diffusion flame lighters can be very short in length as no means for pre-mixing are required. Unfortunately, diffusion flame burners tend to produce soot from unburned hydrocarbons and pyrrole products from incomplete combustion of the gaseous fuel. Additionally, flames produced by diffusion burners tend to be unstable and tend to bend as the burner turns. [0003] The formation of premixed flames in gas ...
