Mixed burner

Abstract

The invention relates to the technical field of fuel gas equipment, in particular to a mixed burner which comprises a furnace base and a furnace end, and further comprises a furnace end fire distribution core detachably installed in the furnace end and used for gas outlet combustion and a flow guide disc installed at the bottom of the furnace end fire distribution core in an attached mode and used for distributing the direction of premixed gas, and a first premixing bin is formed on the furnace base. The flow guide disc is provided with a flow guide hole, premixed gas flows into the flow guide hole after being shunted by the flow guide disc, and then flows to the burner fire distribution core from the flow guide hole. The furnace end comprises a funnel part and a combustion part, the bottom of the funnel part is connected to the top of the furnace base, and a space formed between the bottom of the funnel part and the flow guide disc is a second premixing bin. In conclusion, due to the arrangement of the flow guide disc, the injection speed of the flame is reduced by reducing the injection speed of the premixed gas, and finally noise generated during combustion of the burner is reduced. A second premixing bin is formed, the premixing effect is more sufficient and efficient, and the heat efficiency is effectively improved. The flameout and backfire phenomena of the burner are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a hybrid burner. Background technique [0002] At present, there are mainly two types of commercial burners, one is directly connected to combustible gas for combustion, and the other is to premix combustible gas and air first, and then pass it into the premixed gas stove for combustion. The former is mainly for household use; The latter is mainly used in commercial kitchens such as canteens, restaurants, hotels, and food processing plants, and is characterized by high power, fast heating, and fast tempering. [0003] Among the currently commonly used premixed gas stoves, there is a burner that is the most popular among consumers. Its structure includes a base with a lower end and a burner at the upper end. Place a fire distribution device, and the inner wall of the fire distribution device is provided with several circularly arranged gas injection ports, and the combustib...

Problems solved by technology

[0004] The premixed combustion stove with the above structure, because the premixed gas is directly ejected from the burner through the gas injection port, the flame injection speed is fast, the noise is large, and the thermal efficiency is low, and because the combustible gas is premixed, the flame injection speed is too high It will quickly cause insufficient premixing, prone to air-fuel phenomenon or combustion instability when the flame is large and small
