Tube Radiant Heaters

Heating large buildings requires a lot of energy, so it is particularly important to heat only what is needed and not lose heat when the door is opened. To avoid this heat loss, radiant tube heaters are usually used. The fan is mainly responsible for heat dissipation control, temperature uniformity optimization, combustion efficiency improvement and emission management in radiant tube heaters. It is a key component to ensure the safe and efficient operation of the equipment.

 

Ventilation and Coling Fan

  1. Heat dissipation and temperature control

 

  • Equipment cooling: The surface temperature of the radiant tube can reach 800-1000℃. The fan drives the air to flow through the surface of the tube, transferring the heat to the surrounding environment or the waste heat recovery system to prevent the equipment from overheating (temperature rise ≤50℃).
    • Data: For every 10% increase in air volume, the heat dissipation efficiency increases by 8%-12%.
  • Waste heat utilization: Some systems direct the hot air to the preheating area (such as preheating before metal annealing), and the comprehensive energy saving rate is >15%.

 

  1. Temperature uniformity optimization

 

  • Forced convection: In the heat treatment furnace, the fan circulates hot air (wind speed 1-3m/s), eliminates radiation dead corners, and reduces the temperature difference in the furnace from ±20℃ to ±5℃.
    • Case: A heat treatment line for automotive parts uses multiple fans to supply air in different areas, and the uniformity of product hardness is increased to 98%.
  • Dynamic adjustment: The PID algorithm adjusts the fan speed according to temperature feedback, and the response time is <1 second (such as ceramic fiber furnace).

 

  1. Combustion support and emission management

 

  • Gas radiant tube combustion: The fan provides the combustion chamber with an appropriate amount of oxygen (air-fuel ratio 10:1) to ensure that the gas (such as natural gas) is fully burned (CO emissions <50ppm).
  • Exhaust gas emissions: The combustion exhaust gas (including NOx, CO₂) is guided to the treatment device (such as SCR denitrification), in accordance with GB 16297-2012 standards.

 

  1. Energy efficiency improvement

 

  • Heat recovery design: The fan drives the flue gas waste heat to preheat the combustion air (heat exchange efficiency >70%), reducing gas consumption by 10%-20%.
  • Frequency conversion control: Adjust the fan power according to the load demand (such as 30% speed reduction at low load at night), reducing energy consumption by 15%-25%.
