CFD modeling improves burner performance

The computed velocity distribution of the baseline burner (standard SVG-125, 1 MMBtu/hr at 10% excess air and 16osig) is shown in Fig. 6. The CFD computed mean burner nozzle exit velocity is 660 ft/s. Based on laboratory exit gas-temperature profile measurements, gas density calculations based on the ideal gas equation of state and subsequent exit velocity determination via conservation of mass, the average calculated exit velocity was 567 ft/s, which [Hauck] considers the highest in the industry.
