Injection type air blast type combusting device for gas stove

Abstract

The invention discloses an ejection-type air blast burner used for a gas stove, which comprises an injector, a gas connector, a gas nozzle, a combustor, a firework stabilizing holes component, an air chamber and an axial flow fan. One loop of secondary air ports are arranged on the fringe of the bottom of the combustor. The firework stabilizing holes component is uniformly distributed on the bottom of the combustor. The bottom of the firework stabilizing holes component is communicated with the head of the injector. The tail of the injector is connected with the axial fan through the air chamber. The firework stabilizing holes component comprises a fire hole main body, a central bore arranged on the fire hole main body, a cross notch arranged on the top of the central hole, thus forming a main fire hole. The end of the cross notch is provided with a subsidiary firework stabilizing hole communicated with the main fire hole. The sectional area of the air duct of the subsidiary firework stabilizing hole is larger than the sectional area of the air duct of the main fire hole. A spoiler inclining outwards is arranged above the outer side of the subsidiary fire hole. Besides solving the problem of incomplete burning, the burner can effectively control the total excess air, and has the characteristics of complete burning, stableness and high thermal efficiency.

Description

technical field [0001] The invention belongs to the technology of gas burners, and in particular relates to an injection type blast burner for a gas stove. Background technique [0002] Household gas cookers have always used low-pressure ejector-type atmospheric burners. This kind of burner has a low heat intensity (the firepower is relatively scattered), which is more suitable for Westerners who are used to frying and grilling food, but it is not suitable for people who are used to For the orientals who stir-fry dishes, household stoves using such burners often cannot meet the needs of cooking. In recent years, many manufacturers have continuously introduced high-power gas stoves to try to meet this demand, but on the one hand The national standard does not allow the heating power to be too large. On the other hand, the excessive heat load leads to a significant drop in heating efficiency. At the same time, a large amount of high-temperature flue gas is discharged into the ...

AI Technical Summary

Problems solved by technology

Since the heat intensity of the low-pressure injection burner is limited by the gas pressure, and the gas pressure cannot be increased by the urban gas pipeline network, the blast burner is the best choice, but the complete blast burner requires more energy. Large fans, high energy consumption, high noise, and difficult to control the combustion conditions, these technical routes are not the best choice

[0004] In addition, intensified combustion often brings about the problem of excessive carbon monoxide concentration in flue gas due to incomplete combustion. How to solve it will be a technical problem faced by intensified combustion
