Abstract:
An improved staged combustion method useful with oxy-fuel combustion and in a furnace which contains a charge, wherein substoichiometric combustion and secondary oxidant injection are carried out in an orientation which forms a more oxidizing atmosphere proximate the charge surface and oxidizing gas recirculates from the secondary oxidant stream to the charge surface and back to the secondary oxidant stream.

Abstract:
An improved staged combustion method useful with oxy-fuel combustion and in a furnace which contains a charge, wherein substoichiometric combustion and secondary oxidant injection are carried out in an orientation which forms a more oxidizing or a more reducing atmosphere proximate the charge surface than would be the case with a homogeneous furnace atmosphere.
