ABSTRACT:
A burner for the flash oxidation of particles of metal concentrates has three downwardly directed, concentrically mounted tubes each having a venturi nozzle on the discharge end thereof. Finely divided metal concentrates introduced into the annular space between the inner tube and the intermediate tube are accelerated by high pressure oxygen introduced through the inner tube to substantially the velocity of an oxidizing gas introduced into the annular space between the intermediate tube and the outer tube. Means are provided for adjusting the extent that the nozzles on the ends of the inner tube and intermediate tube extend into the nozzles on the ends of the intermediate and outer tubes respectively.
