US Classification:

75414, 75687, 431 2, 431 12

Abstract:

A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase.

International Classification:

C21B 7/00

US Classification:

266 44

Abstract:

The present invention is a method of integrating oxygen production with blast furnace operation. A heated air stream is introduced to an ion transfer membrane separator, producing a permeate and a retentate. The permeate and the motive stream are introduced into an ejector jet pump producing an oxygen enriched stream. The oxygen enriched stream is introduced into blast furnace. In another embodiment of the present invention, the permeate and a steam motive stream are introduced into an ejector jet pump. Heated air inlet stream is introduced into a cascading series of ion transfer membrane separators, producing a series of permeate streams and a series of retentate streams wherein each retentate stream acts as the input stream for the subsequent ion transfer membrane separator. Thereby producing a series of oxygen enriched streams which are combined and introduced into blast furnace.
