Abstract
A method useful with oxy-fuel combustion and in a furnace which contains molten material, wherein either substoichiometric or superstoichiometric combustion and low velocity injection of fuel and primary and secondary oxidant in an oxy-fuel burner are carried out in an orientation which forms either a reducing or oxidizing atmosphere proximate the molten surface.
