CIRCUMFERENTIAL INJECTION BURNER

摘要

A burner for delivering pulverous feed material and reaction gas to a reaction vessel comprises an outer, elongate tubular member having a peripheral wall. An upper end of the outer tubular member defines a gas supply channel for receiving the reaction gas; a lower end defines a mixing chamber for the reaction gas and the feed material; and an intermediate portion located between the upper and lower ends may have at least one aperture through its outer peripheral wall for receiving the feed material. The burner may comprise an adjustable disperser located inside the outer tubular member and extending from the upper end to the lower end of the outer tubular member. An inner tubular member may be located inside the outer tubular member to define an outer annular passageway, and a valve may be provided for controlling an area of an annular opening of the outer passageway.
