Patent ID: 8152514

Claim:
An oil/slurry burner with injection atomization for the gasification of solids-containing liquid fuels, comprising: a cooled housing, wherein a coiled tube provides cooling; a pilot burner section centrally arranged in the cooled housing comprising a pilot burner passageway, comprising a separate pilot burner section cooling system; an annular passageway arranged in the cooled housing concentric with the pilot burner passageway and comprising an annular passageway outlet disposed at a downstream end of the oil/slurry burner, where the annular passageway supplies an oxidant, wherein the annular passageway is cooled by a separate annular passageway cooling system; a plurality of supply tubes concentrically arranged outside the annular passageway, wherein each of the supply tubes delivers a liquid fuel flow to a supply tube outlet disposed at the downstream end of the oil/slurry burner adjacent to and radially outward of the annular passageway outlet, wherein the individual supply tubes are implemented mutually straight and are inclined radially inward toward a longitudinal axis of the burner in a direction of the oil/slurry burner downstream end; and an atomizing agent feeding element that supplies an atomizing agent to the liquid fuel, comprising an atomizing agent feeding element outlet disposed at the downstream end of the oil/slurry burner; wherein the annular passageway, the supply tubes, and the atomizing agent feeding element are configured to keep the oxidant, the liquid fuel flow, and the atomizing agent discrete from each other throughout the oil/slurry burner.
