    摘要: The invention relates to a burner, particularly Low-NOX-burner, for generating a flame by combustion of a fuel, comprising: a tile (15, 15a, 15b) surrounding an opening (2, 2a, 2b) of the tile (15, 15a, 15b) extending along a burner axis (12), the tile (15, 15a, 15b) further comprising a front side (20) and a rear side (21) facing away from the front side (20), wherein the rear side (21) comprises an air inlet (10, 10a, 10b) connected to said opening for feeding air (A, A′, A″) into said opening (2, 2a, 2b), and wherein said front side (20) comprises a discharge outlet (9, 9a, 9b) connected to said opening (2, 2a, 2b) for discharging a flame (30) generated by the burner (1) into a surrounding area (S), and wherein the tile (15, 15a, 15b) further comprises an inside (22) facing said opening (2, 2a, 2b) as well as an outside (23) facing away from said opening (2, 2a, 2b). According to the invention the burner (1) further comprises at least one oxygen lance (5) extending along the burner axis (12) in a first recess (17) of said tile (15, 15a, 15b), the at least one oxygen lance (5) having an ejection nozzle (6) at an end region of the at least one oxygen lance (5) for ejecting oxygen (O), particularly such that the oxygen (O) is at first ejected into a colder flue gas region (31) surrounding the relatively hotter flame (30) generated by the burner (1). Further, the invention relates to a method for generating a flame (30).

    摘要: The invention relates to a combined fluidized bed and pulverized coal combustion method and system. In the method, fluidizing air (4) is injected into a fluidized bed (2) situated in the bottom portion of the combustion chamber (3). Into the combustion chamber, to above the fluidized bed (2), is fed a mixture of pulverized coal and a carrier gas from a second set of fuel feed means (6) at a mass flow rate which is higher or at least substantially equal to the upper ignition limit of the mixture, and the mixture of the pulverized coal and the carrier gas at least by the fluidizing air (4), and at least a fraction of the fuel fed via the second set of fuel feed means (6) is combusted above the fluidized bed (2).

    摘要: A pulse combustor apparatus for burning solid fuel comprises a Rijke-type combustor tube and has a rotating fuel bed for defining a primary combustion zone adjacent the fuel bed. The rotating fuel bed tends to minimize agglomeration of solid fuel and accumulation of ash during combustion by agitating the solid fuel. An inlet conduit is provided for introducing a low nitrogen gaseous fuel to the combustion air upstream of the combustion zone to minimize the formation of NO.sub.x in the primary combustion zone. In other embodiments, inlets are provided downstream of the primary combustion zone for introducing additional air or gaseous, low nitrogen fuel for air staging or reburning to minimize the emission of NO.sub.x. Sorbents, such as limestone, are introduced above the bed to minimize SO.sub.2 emissions.
