Abstract

Burners, within tubes projecting into material processed by countercurrent heating gases, within a shaft furnace for decarbonation or kilning are modified to utilise e.g heavy fuel oil (instead of only gas fuels, or liquids with F.B. Pt less than 180 degrees C); by atomising with e.g. air introduced through a pipe coaxial with nozzle fuel feed tube, or by employing mechanical atomisation. Combustion prodts. are recycled through projecting tubes around burners, and nozzles (which are recessed, to provide protection, against radiation and prodt. abrasion) are pref. screw fitted inside coaxial air feed pipes, for ease of dismantling, and adjustment of atomising air flow.
