Abstract

The invention discloses a full-premix burner, and relates to the technical field of burners. The full-premix burner comprises a fan, a mixing chamber shell, a burning head and an igniter, wherein the mixing chamber shell is connected between the fan and the burning head; an air main pipe and a gas main pipe are arranged in the mixing chamber shell; multiple air branch pipes communicate to the air main pipe; multiple gas branch pipes communicate to the gas main pipe; the outlet ends of the air branch pipes are deviated from the fan; the multiple gas branch pipes communicate to the air branch pipes in a one-to-one corresponding way; a connecting plate is arranged between the air branch pipes and the burning head; two ends of the connecting plate are in sealed connection with the multiple air branch pipes and the burning head; and air guiding holes corresponding to the multiple air branch pipes are formed in the connecting plate. The full-premix burner provided by the invention has the effects of simple structure, low processing cost, a good mixing effect of gas and air, and a stable mixing result.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a fully premixed burner. Background technique [0002] A burner is a general term for a device that makes fuel and air spray out in a certain way or mixed out for combustion, including a fully premixed burner. The fully premixed burner is a device that fully mixes the gas and air before the gas is ignited, and then the mixed gas formed by the mixture is discharged and ignited. The fully premixed burner has the advantages of sufficient combustion, high flame temperature, and less harmful gas emissions such as CO and NOx. [0003] In the prior art, a mixing device is usually used to mix gas and air. The existing authorized publication number is CN206669740U patent document (reference document) discloses a fully premixed metal fiber burner, including a fan, a premixing chamber and a combustion head, the air outlet of the fan is connected to the premixing chamber The front end of ...
