Abstract

<PICT:0956692/C1/1> A method of heating particulate material e.g. crushed ore comprises separating the mixture of charge and added fuel into fine and coarse fractions, introducing the fine fraction together with air into an annular chamber 6, and introducing the coarse fraction together with air into cylindrical chamber 8 of a cyclone furnace. As shown, separator 2 divides the charge into fine and coarse fractions. The fine fraction passes through tubes 3 to tangential ports 5 from which it enters annulus 6 together with air 4 which may be enriched with oxygen. The coarse fraction passes through tube 7 into cylindrical chamber 8 and a tangentially arranged tube 9 introducing air 10 causes centrifuging of the coarse fraction to the periphery of the cylinder 8. The main combustion air 11 enters cylinder 8 tangentially at 12. The melt is discharged from cylinder 8 through a nozzle 15 into a settling furnace 14.
