Description

High-efficiency concentrated energy burner

【Technical field】

The invention belongs to a burner, in particular to a high-efficiency energy-gathering burner for high-efficiency combustion.

【Background technique】

In the prior art, the burner is the most important part of the cooker. Whether the structure of the burner is scientific or not critically determines the quality of the whole cooker. The current burner generally adopts an ejector structure, and the gas is injected into the burner through the nozzle. Inside the burner, the air and gas are mixed evenly in the air mixing chamber. According to the position of the air introduction, it can be divided into two structures: the upper air inlet and the lower air inlet. An annular fire cover is placed on the seat to emit fire. There are multiple independent outer fire covers that share the same air mixing chamber above the air mixing chamber of the combustion seat. Most of the burners with these structures have secondary burners in actual use. Insufficient air replenishment, insufficient combustion, uneven heating and other disadvantages.

【Content of invention】

The invention provides a high-efficiency fuel injection pipe in the center of the burner that divides the gas into two or more split air passages to independent burners and the center of each independent burner has a secondary air supplementary channel, which is more complete in combustion and higher in heating efficiency. Focus burner.

To achieve the above object, the present invention provides the following technical solutions:

The high-efficiency energy-concentrating burner includes a burner, a burner seat and a combustion seat. The inner and outer injection pipes on the burner are respectively connected to the bottom of the burner seat, and the burner seat is provided with inner ring channels from the inside to the outside. and the outer ring channel, the combustion seat is installed on the upper part of the burner seat; the gas outlets on the combustion seat are arranged in a petal shape, and the inner ring gas outlet connected with the inner ring channel is arranged in the center of the combustion seat. The upper cover of the ring gas outlet is provided with a central fire cover; the combustion seat is evenly distributed with a plurality of outer ring gas outlets with the inner ring gas outlet as the center, and the outer ring channel with the burner seat and each outer ring are formed in the combustion seat. The branch passages connected to the gas outlets respectively. The upper cover of each outer ring gas outlet of the combustion seat is provided with an outer fire cover. The outer fire cover and each outer ring gas outlet form an independent burner. Arranged in a ring, the center of each independent burner is provided with a secondary air supplementary channel; the central fire cover is formed into a ring-shaped stepped structure, and the outer wall surface of the upper side step of the central fire cover is provided with a plurality of central main fire holes in the circumferential direction, and the central fire cover The outer wall of the lower step is provided with a plurality of ignition holes in the circumferential direction; each outer fire cover is cylindrical, and the upper side of the outer wall of each outer fire cover is provided with an outer main fire hole connected with a branch channel. Both sides are provided with flame stabilizing holes communicating with the branch passages; the ring is arranged around the outer wall surface of the step on the lower side of the central fire cover, and there is no ignition hole adjacent to the outer wall of each outer fire cover. There are no outer main fire holes arranged on the outer side walls of each outer fire cover adjacent to the outer side wall of the step.

Preferably, the outer fire cap is in the shape of a cylinder whose outer wall is sunken inward.

The beneficial effects of the present invention are:

In the present invention, the ignition hole around the outer wall surface of the lower side step of the central fire cover and the outer main fire hole adjacent to the outer side wall of each outer fire cover are not provided with a fire hole, which can effectively prevent the outer main fire hole from burning when the burner burns. The cross-combustion of the fire and the central flame will cause insufficient combustion of the burner, insufficient secondary air supplementation, fire-off, flame-off and other phenomena; The air mixing chamber of the burner, each independent burner center has a secondary air supplementary channel, which can make the burner burn more fully and have higher heating efficiency.

【detailed description】

The high-efficiency energy-concentrating burner, as shown in Figures 1 to 4, includes a burner head 1, a burner head seat 2 and a combustion seat 3. The inner and outer ejector tubes on the burner head 1 are respectively connected to the bottom of the burner head seat. The head seat 2 is respectively provided with an inner ring passage 4 and an outer ring passage 5 from the inside to the outside, and the combustion seat 3 is installed on the upper part of the burner head seat; 3 The center is provided with an inner ring gas outlet 30 communicating with the inner ring channel, and the upper cover of the inner ring gas outlet 30 of the combustion seat 3 is provided with a central fire cover 6; on the combustion seat 3, there are less than four inner ring gas outlets evenly distributed in the circumferential direction 30 as the center of the outer ring gas outlet 31, and the combustion seat 3 forms a branch channel 7 communicating with the outer ring channel 5 of the burner seat 2 and each outer ring gas outlet 31 respectively, and each outer ring gas outlet of the combustion seat 3 31. The upper cover is provided with an outer fire cover 8. The outer fire cover 8 and the outer ring gas outlet 31 form an independent burner. The independent burners are arranged in a ring along the central fire cover 6.
