    Abstract: In order to provide a rotary-furnace burner in which the quantity fraction of cost-effective particulate secondary fuels to be used as energy carriers can be increased and the configuration of the burner flame can be influenced, even during the operation of the burner, it is proposed, according to the invention, to arrange an expansion chamber open towards the burner mouth and having a widened cross section, as compared with the tube or individual tubes in the burner in front of the issue of the tube or tubes for blowing out the secondary fuels, and to make the axial length and the volume of the expansion chamber variable, during the operation of the burner, by means of the axial displacement of the secondary-fuel tubes, so that the particulate secondary fuel particles blown out at the burner mouth with a considerably reduced velocity do not fly past the burner flame, but, instead, burn out in the flame.

    Abstract: A burner comprises a body, a nozzle, and at least one attachment element for removably attaching the nozzle to the body. The body defines an oxidant inlet, a feedstock inlet, a body outlet, and one or more passages for conveying the oxidant from the oxidant inlet to the body outlet and for conveying the gasification feedstock from the feedstock inlet to the body outlet. The nozzle defines a nozzle inlet and a nozzle outlet, wherein the nozzle inlet is configured to receive the oxidant and the gasification feedstock from the body outlet and the nozzle outlet is configured to discharge the oxidant and the gasification feedstock into the reaction chamber. The at least one attachment element removably attaches the nozzle to the body such that the nozzle inlet is in fluid flow communication with the body outlet when the nozzle is attached to the body.

    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.
