Precision Measurement of Protective Heat Treating Atmospheres
According to DOE studies – minimizing combustion air can deliver 35% savings
Checking and tuning air/fuel ratios is one of the simplest ways to get maximum efficiency out of fossil fuel fired process heat equipment.

Why Air/Fuel Monitoring is Important
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 gasses
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
