Fuel gas combustion device called a gas burner, industrial furnace habit of name and chemical heating unit for natural gas combustion devices, as well as some used to call the gas burners. Categories: In accordance with the level of gas pressure before burner: low pressure gas burner: gas pressure in 5kpa less. High pressure gas burner: gas pressure in 5kpa more. Type according to the shape of the flame: straight flame burner: also known as long-flame burner, flame longer, use more general kiln. Short-flame burner: Flame short and rigid. Flame burner: flame close to the furnace wall or roof interior spray evenly spread to the surrounding disc shape. An air supply mode Category: Self-priming burner: burner does not need outside help with the wind, itself a venturi-type structure, the outside air can be inhaled, generally less power burner. Air Distribution burner: forced to rely on with the combustion air blower fan is usually high pressure centrifugal fan. According to the air-fuel mixture Method: Diffusion-type burner: the air needed for combustion and not pre-mixed gas. Atmospheric burner: also known as semi-premixed gas burner. Needed for combustion air portion is mixed with natural gas. Fully premixed burners: combustion air required in advance and gas mixing, usually used in flameless combustion type burner. Special functional classification: can be divided into regenerative burners, radiant tube burner, thermostat burner, low nitrogen burners, and other new energy-saving burner. Uses: Natural gas burner is commonly used in the industrial furnace combustion apparatus, gas burners performance will largely affect the quality of products, reasonable and efficient gas burner should be able to meet the furnace combustion, heating and production processes the conditions required by the full. Burner common sense: the burning of natural gas is generally divided into three processes: the gas-air mixture; heating the gas mixture and ignition; combustion gas mixture. Flame stable condition, the flame propagation velocity and flow rate of combustible gas mixture equal and opposite. Stable combustion: gas and air mix faster than the flame propagation speed cause the flame to leave the stable point. Tempering burner: gas and air mixing rate is less than the flame propagation speed, flame spray inside the burner. Burners from the fire and tempering is not ideal combustion burner status, use of stable flame burner plate structure to achieve good status.
