摘要： A burner includes a first oxidant conduit to transmit a first stream of an oxidant; a solid fuel conduit having an outtake and surrounding the first oxidant conduit, thereby forming a first annulus to transmit a mixture of a transport gas and particles of a solid fuel; a second oxidant conduit surrounding the solid fuel conduit, thereby forming a second annulus to transmit a second stream of the oxidant or an other oxidant; and means for segregating the mixture proximate the outtake into a lean fraction stream and a dense fraction stream. The first stream of the oxidant exiting the first oxidant conduit combines during combustion with the lean fraction stream, thereby forming an inner combustion zone adjacent the outtake, and the second stream of the oxidant, or the other oxidant, exiting the second oxidant conduit combines during combustion with the dense fraction stream, thereby forming an outer combustion zone.

摘要： A symmetric device for stabilization of a flame includes a primary oxidant pipe and a fuel pipe. The fuel pipe is internal to the primary oxidant pipe creating a primary oxidant conduit. A secondary oxidant pipe is internal to the fuel pipe creating a fuel conduit. A primary oxidant source supplies oxidant to the primary oxidant conduit. A fuel source supplies fuel to the fuel conduit. A secondary oxidant source supplies oxidant to the secondary oxidant pipe. The first oxidant velocity is greater than the second oxidant velocity and the fuel velocity is less than the second oxidant velocity. The primary oxidant pipe end extends past the fuel pipe forward end and the fuel pipe forward end extends past the secondary oxidant pipe end. A mismatch in velocity between fuel and oxidant generates a large scale vortex. An asymmetric embodiment is also provided.
