Abstract

The invention belongs to the technical field of combustors, and particularly provides a tertiary air mixed gas combustion device. The tertiary air mixed gas combustion device comprises an injection pipe. The bottom of the injection pipe is in screw joint with a connecting disc, a nozzle is welded to the connecting disc, the bottom of the nozzle penetrates through the connecting disc and is connected with a gas supply pipeline, and air inlets are evenly formed in the outer wall of the injection pipe. Gas is sprayed from the nozzle, the gas and air are mixed in the injection pipe for the first time, the gas and the air are mixed for the second time through an open type gas mixing chamber after the mixed gas passes through the upper end of the injection pipe, and as the mixed gas sprayed at ahigh speed does not have other resistance besides air in the open type gas mixing chamber, the gas can entrain the mixed air to the maximum degree. When the mixed gas moving at a high speed rises totouch a floating flame preventing device, the ignited gas can be attached to the upper portion of the floating frame preventing device for combustion according to the wall attachment effect of the moving gas, and combustion is safe and stable.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a tertiary mixed air gas combustion device. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners are divided into industrial burners, burners, civil burners, and special burners according to types and application fields. Basic introduction concept In the broad concept of burners, household water heaters, gas stoves, and even lighters can all be considered as a type of burner. At present, burners exceeding 25KW in the Chinese food stove industry generally require a blower to support combustion, but the disadvantages are high noise, low efficiency, troublesome use and maintenance, and high production costs. So need to improve this, reduce above-mentioned shortcoming. Contents of the invention [0003] The purpose of the present invention is to provide a tertiary air-mixed gas combustion de...
