Abstract

The invention provides a combustor which comprises an injection mixer, an external fire injection nozzle, an internal fire injection nozzle, a gas flow distribution chamber, an external combustor head and an internal combustor head, wherein the external combustor head is provided with an internal conical surface and an external conical surface; the peaks of the internal and external conical surfaces are positioned at the highest point of the horizontal position of a circular ring at the external combustor head; strip-type external ring main fire slots and external ring flame stabilizing slots are formed in the external combustor head, and the number of the strip-type external ring main fire slots is the same as that of the external ring flame stabilizing slots; internal main fire holes and internal flame stabilizing holes are formed in the internal combustor head, and the number of the internal main fire holes is the same as that of the internal flame stabilizing holes. The combustor provided by the invention has the advantages that 1, precise control on a primary air coefficient of fuel gas during combustion is guaranteed, the fuel gas can be combusted more fully without adjusting an air door during combustion, emission of harmful gas is reduced, and high environment friendliness is realized; 2, due to the arrangement of the external ring main fire slots and the external ring flame stabilizing slots, the stability of flame during combustion is guaranteed, the heat efficiency of fuel gas combustion is improved, and the using amount of the fuel gas is reduced.

Description

technical field [0001] The invention provides a burner, especially an atmospheric burner. Background technique [0002] Civil stoves all use the atmospheric combustion method, because this kind of burner is pre-mixed with part of the air, which makes the combustion flame short, strong firepower, high temperature, and the combustion efficiency is higher than that of the diffusion combustion method. It can also burn gases of different properties. , safe combustion, can be applied to low-pressure gas, and does not require other power equipment, so it is more suitable for civilian burning appliances than other combustion methods. However, due to the complexity of the domestic gas source and backward processing technology of the atmospheric burner of traditional cookers, people do not have high requirements for kitchen equipment, as long as they can burn, they do not pay attention to nor pursue accurate and excellent combustion conditions. The capacity is also low, and many prod...
