How to Select the Right Gas Burner for Your Application
In industrial heating, furnaces, drying equipment, and thermal processing lines, the gas burner is the core component that provides reliable and controllable heat. Each application has different requirements for temperature range, flame characteristics, efficiency, and stability—so choosing the right burner is essential.
A properly selected burner not only improves production efficiency but also reduces energy consumption, lowers emissions, and extends equipment lifespan. plus how Ekgas can help you achieve cleaner, safer, and more efficient combustion.Below are six key factors to help you select the right gas burner quickly and accurately.
-
Choose the Burner Type Based on Process Temperature
Different industrial processes operate within different temperature ranges:
Low temperature (200–600°C): Drying ovens, baking equipment
→ Use low- to medium-temperature premix burners, which offer stable and uniform flame control
Medium temperature (600–1200°C): Heat treatment furnaces, annealing furnaces
→ Recommended: modular burners, nozzle-mix burners, proportional control burners
High temperature (above 1200°C): Aluminum melting furnaces, ceramic kilns, forging furnaces
→ Use high-temperature, high-intensity burners or regenerative burners for higher efficiency
Understanding your maximum temperature, heating speed, and holding duration helps narrow down the burner options.
-
Define the Required Heat Output (kW / kcal / BTU)
Heat output determines the burner size and model.
Basic calculation:
Required Heat Output = Heat Needed for the Workpiece + Heat Loss of the Furnace
If precise data is not available, burner capacity can be estimated based on furnace chamber volume
(e.g., medium-temperature furnaces typically require around 350,000–450,000 kcal/m³).
Insufficient output → slow heating, failure to reach target temperature
Oversized burner → long flame, energy waste, unnecessary wear
Your supplier can usually provide accurate recommendations based on chamber dimensions.
-
Select Based on Fuel Type
Common fuel types include:
Natural Gas (NG)
Liquefied Petroleum Gas (LPG)
City Gas
Biogas / Biomethane
Hydrogen (emerging in some industries)
Each fuel has different calorific values and combustion characteristics, which must match the burner’s nozzle design and mixing method.
-
Choose Flame Shape and Velocity According to the Process
Different applications require different flame patterns:
Long flame burners: Suitable for uniform heating, e.g., heat treatment furnaces
Short flame burners: Suitable for compact spaces or localized heating
High-velocity burners: Improve temperature uniformity inside the chamber
Regenerative burners: Up to 40% energy savings for high-energy-demand kilns
Flame velocity, flame hardness, and mixing method (premix or nozzle-mix) are all important selection factors.
-
Select the Control Method: Manual, Proportional, or Fully Automatic
ON/OFF control: Simple and cost-effective
High/low fire control: Suitable for processes with stable temperature requirements
Proportional control (valve + controller): Energy-saving with precise temperature accuracy
Fully automated combustion systems (with ignition, detection, and safety interlocks): The mainstream choice in modern plants
If your facility is transitioning toward automation, a proportional + PLC interlock system is recommended.
-
Consider Installation Conditions and Operating Environment
Other important factors include:
Wall thickness, insertion length
Air supply method (forced draft vs. natural aspiration)
Mounting direction (side, bottom, angled installation)
Ambient temperature, dust levels, humidity
Requirements for explosion protection or anti-backfire design
All these aspects impact the burner’s performance, safety, and lifespan.
Summary: The Golden Steps for Selecting a Gas Burner
Define temperature range and process requirements
Calculate heat output and match the proper model
Confirm fuel type and mixing method
Choose the ideal flame shape and velocity
Select the appropriate control method
Fine-tune based on installation and environmental conditions
By following these six steps, you can confidently choose the right burner and avoid unnecessary cost, performance issues, or energy waste.
