<p>A sleeve (58) for surrounding a nozzle (54), for injecting particulate carbonaceous material, extending into a slagging combustor. Slag which flows along the sleeve is retained by projections (80) such as ribs or pins. The slag strips off into an oxidant flow field, providing a local hot zone to assure combustion closely adjacent to the fuel-ejection orifices of the nozzle.</p> |
