Embodiment 1

[0035] This embodiment provides a stove head, such as Figure 1 to Figure 5 As shown, it includes an outer injection tube 1, an inner injection tube 2, an annular air channel 3 and an inner ring seat 4;

[0036] The outer injection tube 1 and the inner injection tube 2 are arranged side by side, and are connected by fixed feet, the inner injection tube 2 communicates with the inner ring seat 4, and the outer injection tube 1 and the The annular air passage 3 is connected, the annular air passage 3 is arranged around the inner ring seat 4, and both are concentric, and the annular air passage 3 is evenly connected with a plurality of air outlets 5;

[0037] The outer injection pipe 1 includes a main body 11 and an extension part 12. One end of the extension part 12 communicates with the main body 11 and the other end communicates with the annular air passage 3, which is used to improve the primary premixing capacity of gas and air .

[0038] The specific structure is as figur...

Embodiment 2

[0055] This embodiment provides a burner, such as Figure 7 and Figure 8 As shown, the burner includes the burner described in Embodiment 1 and the connecting piece 6, the ignition needle 7, the fire distributor 8 and the fire cover 9, the connecting piece 6 is sleeved on the inner ring seat 4, and is connected with the The annular air passage 3 is connected, the ignition needle 7 is arranged on the connecting piece 6, and the fire distributor 8 is connected with the connecting piece 6;

[0056] The fire cover 9 includes an outer fire cover 91 and an inner fire cover 92 , the outer fire cover 91 is matched on the fire distributor 8 , and the inner fire cover 92 is matched on the inner ring seat 4 .

[0057] In this way, the cavity of the entire burner is reduced by the burner head of the embodiment 1, so as to avoid the problem of tempering noise caused by a larger cavity of the burner; at the same time, the fire distributor 8 can be supported by the connecting piece 6 .

Abstract

The invention discloses a furnace end and a combustor. The furnace end comprises an outer injection pipe, an inner injection pipe, an annular air channel and an inner ring seat; the inner injection pipe is communicated with the inner ring seat, the outer injection pipe is communicated with the annular air passage, the annular air passage surrounds the inner ring seat and is concentric with the inner ring seat, and a plurality of air outlets are uniformly communicated with the annular air passage; and the outer injection pipe comprises a body and an extending part, one end of the extending partis communicated with the body, and the other end of the extending part is communicated with the annular air channel for improving the primary premixing capacity of fuel gas and air. The extension part is arranged to lengthen the outer injection pipe, so that the one-time premixing capacity of fuel gas and air is effectively improved; meanwhile, through the arrangement of the annular gas channel,the whole combustor is provided with a small cavity, the problem of tempering noise caused by a large cavity of the combustor is avoided, materials are saved, the gas outlets are evenly formed in theannular gas channel, premixed fuel gas can stably flow out, and the combustion efficiency of the combustor is improved; and therefore, the problems of low energy efficiency and low load of the existing gas stove are solved.

Description

technical field [0001] The invention belongs to the technical field of gas stoves, and in particular relates to a stove head and a burner. Background technique [0002] In the current atmospheric gas stoves on the market, due to the fixed volume limit of the inner space of the stove, the ejector tube of the burner basically extends to the burner and is directly connected to the burner. This produces the following defects, the distance from the air inlet of the injection pipe to the gas outlet connected to the burner is limited to a relatively small length, and the gas and air cannot be fully mixed in the short injection channel. Thereby affecting the combustion efficiency of the burner, resulting in low efficiency and low load of the gas stove. Contents of the invention [0003] In order to solve the above problems, the present invention provides a burner head, which solves the problems of low energy efficiency and low load in the existing gas stoves by providing an annul...
