Gas burner

Abstract

A fuel burner is provided, which relates to the structure modified fuel burner on domestic appliances, and solves the defect of the fuel burner on domestic appliances on present market that has low heat efficiency, high degree of environment pollution and waste of fuel during burning. The furl burner is composed of a first grade mixer, a second grade mixer, a third grade mixer, a diffuser disperser and a mesh enclosure. The invention has the advantages that: the air shall enter in three time to realize the three times mixing of fuel and air, which increases the oxygen content in the mixing fuel and forms mixing fuel with rich oxygen; therefore, oxidizing flames are achieved during burning and stable oxidizing flame burning is maintained because the burning is performed under rich oxygen condition, thereby eliminating the yellow flame, unstable flame and backfire and is able to save the fuel over 50 percent. The invention is capable of being widely installed on domestic appliances.

Description

Technical field: [0001] The invention relates to the improvement of the structure of a gas burner used in a gas cooker. Background technique: [0002] Gas cooker: The national standard stipulates that the thermal efficiency should be greater than 55%, and the CO content in the flue gas should be lower than 500ppm; the gas cooker currently on the market can be divided into: diffusion combustion, atmospheric combustion, partial premixed combustion, Blast combustion, etc., only JZ-ZQS51 gas cooker produced by "Midea" has a thermal efficiency of 58%. It cannot reach more than 60%, and the CO content in the flue gas fluctuates around 500ppm. In the process of using some gas cookers on the market, due to the unreasonable match between the air volume and the gas volume, the flame will appear when the air volume is too large. If it is too small, there will be yellow flames, backfire phenomenon, insufficient combustion of gas, flame temperature does not exceed 800°C, and CO content ...

[0002] Gas cooker: The national standard stipulates that the thermal efficiency should be greater than 55%, and the CO content in the flue gas should be lower than 500ppm; the gas cooker currently on the market can be divided into: diffusion combustion, atmospheric combustion, partial premixed combustion, Blast combustion, etc., only JZ-ZQS51 gas cooker produced by "Midea" has a thermal efficiency of 58%. It cannot reach more than 60%, and the CO content in the flue gas fluctuates around 500ppm. In the process of using some gas cookers on the market, due to the unreasonable match between the air volume and the gas volume, the flame will appear when the air volume is too large. If it is too small, there will be yellow flames, backfire phenomenon, insufficient combustion of gas, flame temperature does not exceed 800°C, and CO content in the flue gas increases, so a large amount of ash will be generated, which will blacken the stove and utensils, and damage the stove. life expectancy, harmful to human health, polluting the environment
