ABSTRACT:
An oxygen-fuel combustion system combines oxygen and fuel to produce a flame. The system distributes oxygen to a stream of fluidized, pulverized, solid fuel at various sites before and after ignition. The system is operable to vary the concentration of oxygen in an oxygen-fuel mixture extant at those sites.
