Abstract

The utility model relates to a ceramic kiln premix gas burner. In the shell of the original burner, a premixing chamber is added between the air duct and the combustion plate. It consists of gas nozzles, air passages, isolation plates, premix chambers, and honeycomb combustion plates. The purpose is to let the gas and air enter the premixing chamber for premixing, and then allow the mixed gas to be remixed during the process of entering the combustion chamber, so that the combustion can be carried out after the gas and air are mixed as fully as possible to improve thermal efficiency. The purpose of reducing energy consumption and reducing harmful gas emissions.

Description

Ceramic kiln premix gas burner

technical field

The utility model relates to a gas burning device for a ceramic kiln, especially capable of saving energy and reducing emissions.

Background technique

The gas burner that ceramic kiln uses at present is made of housing, gas pipeline, air pipeline, combustion chamber, combustion plate, gas channel, air channel. It is to send gas and air to the combustion chamber for mixed combustion through the gas channel and the air channel respectively. called postmixed combustion. In this way, the combustion is carried out while the gas and air are mixed, and the gas and air are not fully mixed. The gas is discharged with the flue gas before it is fully burned and the heat energy is not fully released. The direct consequence is low thermal efficiency and large emissions of harmful gases.

Contents of the invention

In order to overcome the defects of low thermal efficiency and large harmful gas discharge of a ceramic kiln gas burner, the utility model provides a premixed gas burner for a ceramic kiln. The ceramic kiln premixed gas burner can not only improve thermal efficiency, but also reduce harmful gas emission.

The technical scheme adopted by the utility model when solving its technical problems is: in the shell, between the air pipe and the combustion plate, a premixing chamber is added, so that the gas passes through the gas nozzle and the air enters the premixing chamber through the air passage Pre-mixing before combustion, and then the honeycomb design of the combustion plate, so that the mixed gas can be remixed during the process of entering the combustion chamber, so that the combustion can be carried out after the gas and air are mixed as fully as possible, so as to improve thermal efficiency and reduce harmful Purpose of gas emission.

The beneficial effects of the utility model are that the gas can be burned as fully as possible, the thermal efficiency can be improved, the energy consumption can be reduced, and the discharge of harmful gases can be reduced.

Fig. 2 is a structural sectional view of a post-mixed gas burner in a ceramic kiln in the prior art.

Detailed ways

As can be seen from the structural section in Figure 2, the mixed gas burner behind the ceramic kiln is composed of a shell ①, a gas pipeline ②, an air pipeline ③, a combustion chamber ④, a combustion plate ⑤, a gas channel ⑥, and an air channel ⑦. Combustion plate 5. and gas channel 6. are combined at gas pipeline 2. left end. The gas is separated from the air before entering the combustion chamber ④ through the gas channel ⑥. When gas and air enter the combustion chamber ④ at the same time, combustion is also in progress. In the combustion process shown in the structure shown in Figure 2, the air plays a dual role in supporting combustion and moving the gas. While supplying oxygen to the gas to support combustion, a part of the uncombusted gas is pushed out of the combustion chamber ④, and the main component is carbon monoxide, which is discharged into the atmosphere along with the flue gas.

It can be seen from the structural section in Figure 1 that the ceramic kiln premixed gas burner is based on the structure in Figure 2, and a premixed chamber ⑧ is added between the air duct ③ and the combustion plate ⑤. It consists of a gas nozzle ⑨, an air passage ⑦, an isolation plate ⑩, a premixing chamber ⑧, and a honeycomb combustion plate (11). The air channel ⑦ is integrated with the isolation plate ⑩, and the isolation plate ⑩ and the gas nozzle ⑨ are combined at the left end of the gas pipeline ②, and are connected with the premixing chamber ⑧ as a whole. The honeycomb combustion plate (11) is placed between the premix chamber ⑧ and the combustion chamber ④. Its structural principle can be seen that the gas and air are mixed twice to make the mixing and combustion as complete as possible.
