The invention discloses a gas headwind injection gas mixing combustor. The combustor comprises a burning head, a gas pipe, an air cylinder, a fan and a nozzle, and is characterized in that the lower end of the air cylinder is connected with the fan; the upper end of the air cylinder is connected with the burning head; the gas pipe penetrates through the wall of the air cylinder to enter the air cylinder; the nozzle is connected to an outlet end of the gas pipe; an outlet of the gas pipe is downwards; and gas injected by the nozzle is opposite to the wind direction. The gas headwind injection gas mixing combustor has the following beneficial effects: the fuel and air mixing effect is intensified to improve the combustion efficiency; and the length of a mixed gas pipeline is shortened to improve the safety of the gas combustor.
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 gas burners on the market are mostly arranged along the direction of the wind flow velocity, so the mixing effect of gas and air is not good; and the mixing space structure is relatively large, so th...
