Combustor fire cover, combustor and gas stove

Abstract

The invention relates to a combustor fire cover, a combustor and a gas stove. The combustor comprises an inner ring fire combustor and an outer ring fire combustor; the inner ring fire combustor and / or the outer ring fire combustor consist of first combustor bodies and second combustor bodies; the first combustor body and the second combustor body are an atmospheric combustor and an infrared combustor; the first combustor body consists of a first gas mixing cavity, and one or more first fire covers arranged at the top of the first gas mixing cavity; the second combustor body consists of a second gas mixing cavity, and one or more second fire covers arranged at the top of the second gas mixing cavity; and the first fire cover is mounted in the second fire cover in an embedding manner. The combustor fire cover is higher in utilization rate of the heating area, and hardly has heating blind area; atmospheric combustion is adopted in an infrared combustion area, infrared combustion is adopted in an atmospheric combustion area, and the two combustion modes are fused to greatly improve the combustion efficiency; and the firepower is higher, so that Chinese food is cooked more properly.

Description

technical field [0001] The invention relates to a gas stove, in particular to a combined burner and a burner fire cover installed on the gas stove and integrating atmospheric combustion and infrared combustion. Background technique [0002] 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...

AI Technical Summary

Problems solved by technology

The existing combined burners on the market are all dominated by atmospheric combustion, supplemented by far-infrared combustion, and are subject to certain restrictions in terms of energy saving and exhaust emissions.

[0004] In addition, whether it is an atmospheric burner, an infrared burner, or a combination of thick and light burners on the market, the ignition needle and the induction needle are either placed in the center of the burner fire cover or placed between the inner and outer ring fires. This design will not only lead to a large number of heating blind areas on the upper surface of the fire cover, but also make the ignition needle and induction needle endure high temperature heating for a long time, resulting in a reduction in the service life of the ignition needle and induction needle
