This graph shows actual test results of a burner fired with 10% excess air. Other vari- ables such as higher excess air, preheated air temperatures, firing rate, and furnace design can effect NOx emission levels.
Figure 3. NOx Emissions vs. Furnace Temperature.
Custom engineered LE burners rated at 55 mmBtu/h HHV each are mounted on a field erected boiler wall. The burners are designed operate on 500°F combustion air and refinery fuel gas.
