Problems solved by technology

[0002] At present, some of the gas burners used in domestic industrial boilers and power plant boilers are not designed with a flame-stabilizing device, and some are designed with a flame-stabilizing device. Influenced by the influence, it is easy to cause unstable combustion flame, flame defiring, tempering, and fire extinguishing, which will affect the stable operation of the gas burner

Embodiment Construction

[0019] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] Referring to the accompanying drawings, a gas burner with a zigzag flame stabilizer is composed of a nozzle 1, a conical gas nozzle 2, a zigzag flame stabilizer 3, and an air distribution vane 4. The center of the nozzle 1 is provided with a conical gas burner The nozzle 2 is provided with air distribution blades 4 in the circumferential direction between the nozzle 1 and the conical gas nozzle 2, and the sawtooth-shaped flame stabilizer 3 is provided in the circumferential direction of the cone of the conical gas nozzle 2, and the conical gas nozzle 2 is provided with a gas injection hole 5 . The nozzle 1 is made of heat-resistant steel and is a cylindrical cylinder; the conical gas nozzle 2 is made of heat-resistant steel. The front section is a cone with a certain taper, and the rear section is a cyl...

Abstract

The invention discloses a zigzag gas burner. A tapered gas nozzle is formed in the center of the inside of a jet. Air distribution blades are circumferentially formed between the jet and the tapered gas nozzle. Zigzag flame stabilizing bodies are arranged on the circumference of the taped gas nozzle. Gas spraying holes are formed in the tapered gas nozzle. Gas enters from the tapered gas nozzle and is sprayed out through the gas spraying holes. Gas distributed air enters a circular channel between the jet and the tapered gas nozzle and generates rotational-flow distributed air by the aid of the air distribution blades with angles. At the front end of the jet, the gas and the rotational-flow distributed air are intensely mixed and then meet an igniting device to fire. The zigzag gas burner is effective in preventing the flame from lifting, returning and extinguishing.

Description

technical field [0001] The invention relates to a gas burner, in particular to a zigzag gas burner. Background technique [0002] At present, some of the gas burners used in domestic industrial boilers and power plant boilers are not designed with a flame-stabilizing device, and some are designed with a flame-stabilizing device. However, due to poor structural design, external factors such as gas pressure fluctuations and external airflow disturbances may Influenced by the influence, it is easy to cause unstable combustion flame, flame defiring, tempering, and fire extinguishing, which will affect the stable operation of the gas burner. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a sawtooth gas burner, which can stabilize the combustion flame, ensure the stable operation of the gas burner, and have the characteristics of preventing flame defiring, backfire and f...
