International Classification:

F23D 14/58
F23C 5/14
C03B 7/06
F23D 14/32

US Classification:

431 8, 431354, 431187, 65346

Abstract:

An oxy-fuel burner arrangement having a first conduit having a nozzle aperture with an aspect ratio, D1/D2, of greater than or equal to about 2.0. The first conduit is arranged and disposed to provide a first fluid stream, where the first fluid stream is a combustible fuel. The burner arrangement further includes at least one second conduit arranged and disposed to provide a second gas stream circumferentially around the first fluid stream, where the second gas stream includes oxygen. A precombustor is arranged and disposed to receive the first fluid stream and second gas stream where an oxy-fuel flame is produced. The geometry of the nozzle aperture and the cross-sectional geometry of the first conduit are dissimilar.

International Classification:

F23D 14/84
F27D 19/00
F23N 1/02

Abstract:

A transient heating burner including at least two burner elements each including a distribution nozzle configured to flow a first fluid and an annular nozzle surrounding the distribution nozzle and configured to flow a second fluid, the burner also including a controller programmed to independently control the flow of the first fluid to each distribution nozzle such that at least one of the distribution nozzles is active and at least one of the distribution nozzles is passive, wherein flow in an active distribution nozzle is greater than an average flow to the distribution nozzles and flow in a passive distribution nozzle is less than the average flow to the distribution nozzles, wherein the first fluid contains a reactant that is one of fuel and oxidant and the second fluid contains a reactant that is the other of fuel and oxidant.

International Classification:

F27D 19/00
F27D 99/00

Abstract:

A transient heating burner including at least two burner elements each having a distribution nozzle configured to flow a fuel, and an annular nozzle surrounding the distribution nozzle and configured to flow an first oxidant, at least one staging nozzle configured to flow a second oxidant, and a controller programmed to independently control the fuel flow to each distribution nozzle such that at least one of the distribution nozzles is active and at least one of the distribution nozzles is passive, wherein an active distribution nozzle fuel flow is greater than an average fuel flow to the distribution nozzles and a passive nozzle fuel flow is less than the average fuel flow, and to control a staging ratio to be less than or equal to about 75%.
