ABSTRACT:
This burner is so designed as to be capable of operating in a stable manner with no risk of explosion with pure oxygen or air highly enriched with oxygen as the reactant. In one embodiment, a stream of oxygen is delivered through a central tube 4A which terminates in a divergent annular diffuser 30. A mixture of air and pulverized coal is delivered in an intermediate ring 15 around this diffuser and an annular stream of whirling oxygen is delivered in an outer ring 16. Application in indirect heating furnaces, furnaces in which slag exists and cement-making furnaces and in cases where special atmospheres (for example reducing atmospheres) are desired.
