Problems solved by technology

During the use of this type of burner, there are mainly the following problems: 1. It is easy to defire. 2. The residual gas on site is diffused due to incomplete gas combustion. 3. The flame column formed at the outlet of the burner is relatively short, and the flame is "soft". It is not conducive to the increase of the temperature of the bottom of the bag. 4. The gas utilization rate is low, and the baking time is long, which wastes gas energy

Embodiment Construction

[0014] The present invention as Figure 1-3 As shown, it includes a cylindrical body 4, and a gas pipeline and an air pipeline arranged in the body 4, and the air pipeline includes a peripheral air channel 6 and a central air channel 5 coaxial with the body 4; A single number of inner-ring pipeline groups 3 are evenly distributed around the central airway 5, and outer-ring pipeline groups 2 equal in number to the inner-ring pipeline group 3 are evenly distributed around the inner-ring pipeline group 3; the body 4 The inner surface of the inner ring pipe group 3, the outer ring pipe group 2 and the outer surface of the central air channel 5, and the gap between them constitute the peripheral air channel 6.

[0015] It also has a peripheral airway inlet ring 8 , which is arranged outside the body 4 and communicates with the peripheral airway 6 through the through hole 7 opened on the body 4 .

[0016] The rear end of the body 4 is provided with a gas inlet chamber 9 , and the g...

Abstract

The invention discloses a high-efficiency gas burning nozzle and relates to an improvement on the structure of the burning nozzle of a gas burner. The high-efficiency gas burning nozzle can lead gas to be burnt fully, thus improving the burning efficiency of the gas. The high-efficiency gas burning nozzle comprises a barrel-shaped body, gas pipelines and an air pipeline, wherein the gas pipelines and the air pipeline are arranged in the body; the air pipeline comprises a peripheral gas channel and a central gas channel which is coaxial to the body; single-quantity inner-circle pipeline groups are uniformly distributed on the gas pipelines around the central gas channel, and outer-circle pipeline groups which have equal quantity with the inner-circle pipeline groups are also uniformly distributed around the inner-circle pipeline groups; and gaps among the inner surface of the body, the inner-circle pipeline groups, outer-circle pipeline groups and the outer surface of the central gas channel form the peripheral gas channel. In the high-efficiency gas burning nozzle, two circles of gas pipelines are arranged and include an inner circle and an outer circle, and the air pipeline covers the gas pipelines of the inner ring and the outer ring, so that the gas is fully contacted with the air, and further the burning efficiency of the gas is improved. In the high-efficiency gas burning nozzle, the flame lifting is not easy, the diffusion of residual gas is basically avoided, the burning flame is long, the burning is strong and the toasting time is shortened by 1.5-2 hours.

Description

technical field [0001] The invention relates to the improvement of the burner structure of the gas burner. Background technique [0002] Most of the baking medium in the continuous casting machine in the steelmaking plant uses converter gas. At present, most of the gas burners in use are in the form of casing annular seam structure. During the use of this type of burner, there are mainly the following problems: 1. It is easy to defire. 2. The residual gas on site is diffused due to incomplete gas combustion. 3. The flame column formed at the outlet of the burner is relatively short, and the flame is "soft". It is unfavorable for raising the bottom temperature of the bag. 4. The utilization rate of gas is low, and the baking time is long, which wastes gas energy. Contents of the invention [0003] Aiming at the above problems, the present invention provides a high-efficiency gas burner capable of fully burning the gas and further improving the combustion efficiency of the...
