Abstract:
1. Burner apparatus comprising (A) a central feed port having an axis; (B) first supply apparatus for injecting a first stream comprising material selected from the group consisting of fuel, oxidant, and mixtures thereof, through the central feed port along the axis of the central feed port; (C) three or more outer ports, each having an axis which converges or diverges with respect to the axis of the central feed port; and (D) three or more unbranched supply lines, equal in number to the number of outer ports, wherein one end of each of said supply lines is connected to a different one of said supply ports and the other end of each of said supply lines is connected to a controllable supply apparatus for sequentially injecting material selected from the group consisting of fuel, oxidant, inert material, and mixtures thereof, into and through different ones of said supply lines whereby said material is sequentially ejected from different ones of said outer ports as a sequence of second streams having a momentum sufficient to deflect the first stream from the axis of said central feed port, wherein said controllable supply apparatus comprises (E) a valve that comprises a valve body having a valve chamber therein having opposed first and second ends and a side surface extending between said ends, the valve chamber including a first region that extends from the first end of the valve chamber and that has an axis, (F) a controller for turning said valve distributor about its axis so that said channel is sequentially open to different ones of said outlets so as to sequentially provide said material from said open space through said channel to said outlets.
