Abstract: Low NOx emission industrial burner, adapted to operate both in a flame or stage mode and in a flameless mode, so that also the heating step of the chamber of a furnace may be made by means of the same burner, without providing a pilot burner, thus ensuring very low NOx emissions for the whole operation range of the burner and for the whole range of temperatures in the chamber. The combustion process, made by means of said burner, provides for the possibility to combine the stage mode operation with the flameless mode operation.

Abstract: 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.

Abstract: A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.
