Swirl Pulverized Coal Burners

  • Influence of the Inner and Outer Secondary Air Ratios on …

    The swirl burner with a prechamber was used in a 14 MW pulverized-coal combustion experiment to investigate the influence of inner and secondary air ratios (ISA/OSA) on the combustion characteristic and flame shape in this work. The temperatures and species concentrations in the prechamber were measured via the flue gas analyzer and thermocouples. The flame shape beyond the …

    1/1/1985 · Introduction Pulverized-coal burners frequently use swirl to control the near-burner flow field and thereby achieve the desired ignition pattern and flame char- acteristics. Although the general influence of swirl and other burner parameters on the burner flow is known, a more detailed understanding of the in- teraction between flow and combustion is required to ensure optimum design of burners.
