Description

Burner fire cover, burner and gas stove

technical field

The utility model relates to a gas stove, in particular to a combined burner and a burner fire cover which are installed on the gas stove and integrate atmospheric combustion and infrared combustion.

Background technique

Existing burners are generally in two forms, one is an atmospheric burner, and the other is an infrared burner. Among them, the atmospheric burner belongs to the partial premixed combustion method, and the high-temperature flame generated mainly heats the heating object by means of convective heat exchange. There are chemical heat loss and physical heat loss in the process of heating the heating object by the flame. Because the concentration of the premixed gas is relatively high, the stability of the atmospheric burner is better during use, and the heat load adjustment is relatively large. The infrared burner belongs to the complete premixed far-infrared radiation combustion method. The gas uses the entire amount of air required for the premixed gas combustion of the ejector. When burning, the surface of the combustion plate is close to a flameless state, and the combustion plate and the high-temperature flue gas are heated. Compared with atmospheric burners, infrared burners have the advantage of fast heat transfer speed, thus avoiding the problem that a large amount of heat is dissipated to the space without being used due to the short contact time between the flame and the heating object . The characteristics of the infrared combustion method are: extremely low exhaust emission, high thermal efficiency, smaller thermal load adjustment range than the atmospheric combustion method, and a shorter service life of the combustion-supporting plate than the atmospheric fire cover. When the gas source is impure, the pipeline pressure changes, etc. In special cases, ignition difficulties and tempering are prone to occur.

Combining the advantages of the above two burners, a combined burner that combines atmospheric combustion and infrared combustion is disclosed in the prior art.
