Abstract

A gas burner with thick and thin flame distribution, including several combustion units, and there is a gap between two adjacent combustion units; the combustion unit includes an injection pipe, a combustion chamber and a combustion hole located on the upper opening of the combustion chamber , which is special in that: there are small circular combustion holes on the two side walls of the combustion hole; it also includes a flame stabilizing piece, which is arranged on both sides of the combustion unit, and the flame stabilizing piece is connected with the combustion unit There is a gap between the two side wall plates of the body, the upper part of the gap is the flame combustion port, and the lower part is the primary air diversion gap. Due to the adoption of such a structure, the mixture of gas and air is split, and the mixed gas ejected from the combustion hole is combusted with the secondary air outside to form a thick flame. After the air is mixed, it burns to form a weak flame; it overcomes the defects in the prior art that there is only a dense flame, insufficient combustion of the mixture, and high nitrogen oxides; it is energy-saving and environmentally friendly.

Description

A gas burner with thick and thin flame distribution

technical field

The utility model relates to a gas burner for a gas wall hanging furnace or a gas water heater.

Background technique

In the current prior art, a gas burner for a gas wall-hung boiler or a gas water heater includes several combustion units, and there is a gap between two adjacent combustion units; the combustion unit includes an injection pipe, a combustion chamber and Combustion hole located in the upper opening of the combustion chamber. Existing problems are: the mixture of combustion and air burns with the outside air in the combustion hole to form a flame, the combustion heat is concentrated, and the local temperature is high and the content of nitrogen oxides is high.

Utility model content

The purpose of the utility model is to provide a gas burner with dense and thin flame distribution, which can form a thick and thin flame combustion mode, with sufficient secondary air, sufficient combustion and low nitrogen oxide content.

The utility model is achieved in the following way: a gas burner with thick and thin flame distribution, including several combustion units, and there is a gap between two adjacent combustion units; the combustion unit includes an ejector tube, a combustion chamber and The combustion hole located on the upper opening of the combustion chamber is special in that: there are small circular combustion holes on the two side wall plates of the combustion hole;

It also includes a flame stabilizing sheet, the flame stabilizing sheet is arranged on both sides of the combustion unit, there is a gap between the flame stabilizing sheet and the two side walls of the combustion unit, the upper part of the gap is the flame combustion port, and the lower part is the primary air diversion gap.

The gas burner with thick and thin flame distribution is special in that: the upper part of the flame stabilizing sheet forms a combustion gap with the side wall plate of the combustion chamber, and the lower part forms a primary combustion gap with the outer surface of the combustion unit at the lower part of the combustion chamber. Air guide gap.

The gas burner with thick and thin flame distribution is special in that there is an acute angle between the outer surface of the upper part of the flame stabilizing sheet and the outer surface of the upper part.

The utility model is a gas burner with thick and thin flame distribution. Due to the adoption of such a structure, the mixed gas of gas and air is split, and the mixed gas ejected from the combustion hole is combusted with the secondary air outside to form a dense flame. The small circular combustion hole The sprayed mixed gas mixes with the primary air outside in the combustion gap and burns to form a light flame; it overcomes the defects of the prior art that there is only a dense flame, insufficient combustion of the mixed gas, and high nitrogen oxides; it is energy-saving and environmentally friendly.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a gas burner with a thick and thin flame distribution includes several combustion units 1, and there is a gap between two adjacent combustion units 1; the combustion unit 1 includes an injection pipe 2, a combustion unit Chamber 3 and the combustion hole 4 that is located in the upper opening of the combustion chamber 3 .

There are small circular combustion holes 5 on the two side walls of the combustion hole 4;

It also includes a flame stabilizing piece 6, which is arranged on both sides of the combustion unit 1, and there is a gap between the flame stabilizing piece 6 and the two wall panels of the combustion unit 1, and the upper part of the gap is a flame combustion port 61 , The bottom is the primary air diversion gap 62 .

The upper part 64 of the flame stabilizing sheet 6 and the side wall plate of the combustion chamber 3 form a flame combustion port 61 , and the lower part 63 forms a primary air guide gap 62 with the outer surface of the combustion unit 1 at the bottom of the combustion chamber 3 .

There is an acute angle between the outer surface of the lower part 63 of the flame stabilizing sheet 6 and the outer surface of the upper part 64; the lower part of the flame stabilizing sheet 6 and the two side wall plates of the combustion chamber 3 form an air guide gap.

What has been described above is only the preferred implementation of the present utility model. It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the principle of the utility model, which are also regarded as the protection scope of the utility model.
