Efficiency

Increased burner efficiency
Faster ramp to heat
Less fuel per load
Maximizes throughput
Reduce NOx & CO2
Increased radiant tube life

 

Excess air dilutes combustion

Lowers flame temperature
Less heat for the load
More heat in the exhaust gasses
Increase NOx

Optimum excess air for energy efficiency and pollution prevention

10% excess air - yields 2% excess O2 in combustion gases

Excess gas

Sooting in radiant tubes
Lower flame temperature
Unburned fuel
Dangerous gas emissions (higher CO)

Other benefits

Process repeatability
Maximum throughput
Even distribution of heat
Longer radiant tube life
