Industrial Gas Burner

An industrial gas burner is a device that mixes fuel gas (e.g. natural gas, propane) with air and ignites the mixture to produce a controlled high-temperature flame. It is used

 Type of Product
 Industrial burners are categorized by several factors:

• Fuel Type: Burners may use natural gas, propane, or even multi-fuel (liquid or gaseous). Some burners (e.g. oxy-fuel burners) use oxygen instead of air for higher flame temperatures.
• Mixing Method: Atmospheric burners (no blower; air is drawn in by suction) vs forced-draft burners (air blower) vs premix burners (gas and air mixed before the burner head for more uniform flame) vs staged/recuperative/regenerative burners for energy efficiency.
• Flame Type: High-intensity “blue flame” burner’s vs low-emissivity radiant tube burners (for infrared heat)
• Construction: Monoblock burners (one-piece design) vs separate head burners (separate combustion head and blower). Also, indirect-fired burners (combustion products contained) vs direct-fired burners.
• Automation Level: Manual ignition vs automatic electronic ignition; fixed-rate burners vs modulating burners (adjust flame size via valves). Advanced systems include flame monitoring (UV sensors) and digital controls.

Applications in Various Industries
Industrial burners provide process heat in nearly all heating-intensive industries:

• Metal Processing: Furnaces and heat-treatment (annealing, hardening), smelting, forging furnaces.
• Petrochemical and Chemical: Steam generation, reactors, dryers for chemicals or plastics.
• Food Processing: Baking ovens, roasters, dryers for grains or coffee.
• Glass and Ceramics: Kilns for glass melting or ceramic firing.
• Power Generation: Boilers in power plants for steam.
• Building Materials: Cement kiln burners, asphalt production dryers.
• General Manufacturing: Any process requiring hot air or heat (e.g. textile drying, paint curing, waste incineration).
  

  Material Selection Considerations
  Burners must withstand high temperatures, corrosion, and thermal cycling. Common materials include: 

• Burner Body and Housing: Typically fabricated from stainless or carbon steel, often with heat-resistant coatings or linings. The metal must resist oxidation and flame impingement.
• Flame Tubes and Baffles: Made from high-temperature alloys (Inconel, stainless) or ceramic refractory materials. For example, industrial burners often use a refractory baffle to protect the body and stabilize the flame. These refractory components tolerate heat and support the gas nozzle.
• Nozzles and Injectors: Machined from corrosion-resistant metals (e.g. stainless steel); must endure high heat and erosive combustion gases.
• Valves and Regulators: Valves are usually brass or stainless steel; regulators and fittings often brass or steel.
• Seals and Gaskets: High-temp elastomers (silicone or Viton) or metal gaskets in very hot sections.
