Embodiment Construction

[0013] See figure 1 , consists of a combustion head 1, a main gas pipe 2, a gas mixture pipe 3, a fan 4, a nozzle 5, a lower swirl sheet 6, and an upper swirl sheet 7.

[0014] The forced mixing gas burner is characterized in that it includes a combustion head 1, a main gas pipe 2, a gas mixture pipe 3, a fan 4, and a nozzle 5, wherein the fan 4 is connected to the gas mixture pipe 3, and the gas mixture pipe 3 is connected to the combustion head 1. The pipe 2 passes through the wall of the mixed gas pipe 3, and the nozzle 5 is connected to the main gas outlet in the mixed gas pipe 3;

[0015] The spray head 5 is located under the lower swirl sheet 6, or between the lower swirl sheet 6 and the upper swirl sheet 7; the nozzle of the spray head 5 is upward or downward.

[0016] Working principle: The fan 4 supplies air to the gas mixture pipe 3. After the wind passes through the lower swirl plate 6, it will generate a swirling airflow, which enhances the disturbance of the airf...

Abstract

The invention discloses a forced mixing gas combustor. The forced mixing gas combustor is characterized by comprising a combustion head, a main gas pipe, a gas mixing pipe, a fan and a spraying head, wherein the fan is connected to the gas mixing pipe, the gas mixing pipe is connected to the combustion head, the main gas pipe penetrates through the wall of the gas mixing pipe, and the spraying head is connected to a main gas outlet in the gas mixing pipe. A lower whirling plate and an upper whirling plate are arranged in the gas mixing pipe. The forced mixing gas combustor has the advantages that the mixing effect of fuel and air is enhanced, and the combustion efficiency is improved; the length of the gas mixing pipe is reduced, and the safety of the gas combustor is improved; and the guide effect to mixed gas is realized.

Description

technical field [0001] The invention belongs to the technical field of gas burners. Background technique [0002] For gas burners, whether the mixing of gas and air before combustion is sufficient or not is a very important reason that affects the combustion effect. Insufficient mixing will have disadvantages such as insufficient combustion, unstable combustion, loud combustion noise, and high pollutant emissions. At the same time, the size of the mixing space is also an important factor affecting the safety of the gas burner. In order to improve safety, the size of the mixing space should be reduced as much as possible. Therefore, the design of the burner should minimize the size of the mixing space on the premise of ensuring that the gas and air are fully mixed. [0003] The mixing method of gas burners on the market is generally a natural mixing method, and the mixing effect of gas and air is not good, so the mixing space is relatively large and the combustion safety is...
