Combustion-assisting gas burner

Abstract

The invention relates to a combustion-assisting gas burner, mainly comprising a burner core and a cylindrical shell; a main mixing chamber is formed in the cylindrical shell; a main air pipe is communicated with the main mixing chamber through a main air pipe nozzle; the burner core is provided with a group of ignition orifices; one side on middle part of the burner core extends outwards to form alug boss; the other side extends outwards to from an ignition mixing chamber; an energy collecting board in shaped of round platform is arranged in a main hearth outside the burner core 1; the energycollecting board hole on the energy collecting board is communicated with a smoke vent through a smoke chamber in a burner ring; one end of an ignition air nozzle is communicated with an ignition airinlet pipe; and the other end of the ignition air nozzle extends into the ignition mixing chamber. The invention has the beneficial effects that: 1. one side on middle part of the burner core extendsoutwards to form a lug boss, the lug boss is near the bottom of boiler, but the outer ring of the burner is far away from the bottom of boiler, so with the balance, the invention has very even combustion; and 2. a vent is provided for discharging gas, so as to prevent the fan from being damaged by overheating in air return process, and water can be discharged from the vent.

Description

technical field [0001] The invention relates to the field of gas burners, in particular to a combustion-supporting gas burner. Background technique [0002] The gas burner is an important part of a commercial gas stove. Its structure includes a cylinder as a mixing chamber, a furnace core located above the cylinder and an ignition device located on one side or the center of the furnace core. The air inlet and the air inlet, and the air inlet pipe between the air inlet and the cylinder mixing chamber are provided with ball valves. And the working mode of the burner that most gas cooking ranges adopt in the market is: pilot gas arrives furnace core place by pilot pipeline, burns under the ignition of open flame. Under the action of the wind force from the air inlet, the main gas is ignited after quickly reaching the furnace core from the mixing cylinder; the mixed gas is burned above the furnace core to heat the food in the pot. Its deficiency is: 1, find that mixed gas burn...

AI Technical Summary

Problems solved by technology

Its shortcomings are: 1. During use, it is found that the mixed gas burns dark red above the furnace core, and a large amount of residual fire overflows from both sides of the pot. When this burner is working, the mixed gas is not fully burned, and the residual fire cannot be reused.

2. The original furnace core has a cylindrical structure. Since the center of the furnace core is equipped with a ignition nozzle, the air intake in the middle of the furnace core is small, while the air intake in the outer ring is large, resulting in uneven combustion

3. Since the cylinder mixing chamber is a closed cavity, there is no vent hole in the original structure; 2. Water will enter the closed cylinder along the small hole in the furnace core and cannot be discharged
