説明

A unique non-staged burner consisting of a converging splitter nozzle, a converging outer shroud, and inner and outer swirlers is being developed for low NOx emissions. Kerosene was atomized by the annular liquid film twin-fluid nozzle into the air flow from the inner swirler and resulting mixture was injected into combustion chamber from the splitter nozzle which is surrounded by the annular swirling air jet from the outer shroud nozzle. Emissions measurements and imaging of flame and fuel sprays were conducted. The effects of inlet air temperature, fuel temperature and injection positions on NOx levels are discussed based on the changes of flame structure and fuel evaporation with the burner design and experimental parameters. The NOx levels are well correlated with them. Emission Index for NOx well less than 0.5 g/kg-fuel and combustion efficiency greater than 99.9% were simultaneously achieved at adiabatic flame temperatures lower than 1800 K at atmospheric pressure.
