Abstract: The invention provides a rotation-suspension smelting method, in which a powdered sulfide concentrate and an oxygen-containing gas are sprayed into a space within a high-temperature reaction tower through an equipment. The oxygen-containing gas is divided into two parts before entering the equipment: the second oxygen-containing gas is sprayed in the form of an annular direct flow into the reaction tower and forms a bell-shaped wind curtain; and the first oxygen-containing gas is transformed into a rotation-jet via the equipment and jetted into the center of the wind curtain. In the annular space between the two gas flows, the concentrate entering in a direction deviated towards the center is drawn in the rotation-jet, and a high-temperature off-gas from the bottom of the reaction tower is also sucked in, forming a gas-particle mixed two-phase rotation-jet. The sulfide concentrate is ignited by the high temperature, namely, starting a violent combustion reaction with oxygen and releasing SO2-rich off-gas, at the same time, a mixed melt containing matte (or metal) and slag is formed; and the matte (or metal) is finally separated from the slag at the bottom of the reaction tower, thereby completing the metallurgical process. To achieve the process object, the invention also provides a metallurgical equipment and a rotation-suspension smelting burner thereof.

Abstract: In known types of injection systems for a turbine engine combustion chamber, the secondary fuel flow strikes the venturi before entering into the combustor. A new injection system is disclosed to overcome this problem, comprising a first annular deflector surrounded by the bowl of the injection system and extending in the downstream direction from the downstream transverse surface that delimits the downstream side of the swirler. This first deflector has a free downstream end offset in the upstream direction from a downstream end of the bowl, so as to guide an air film output from the first orifices formed through the bowl. The internal radius ψ of the cross section of the first annular deflector increases from the downstream transverse surface as far as the downstream end of the first annular deflector.

Abstract: An axial swirler, in particular for premixing of oxidizer and fuel in gas turbines, includes a series of swirl vanes with a streamline cross-section. Each swirl vane has a leading edge, a trailing edge, and a suction side and a pressure side extending each between the leading and trailing edges. The swirl vanes are arranged around a swirler axis, wherein the leading edges extend essentially in radial direction. Flow slots are formed between the suction side of each swirl vane and the pressure side of its nearest neighboring swirl vane. Furthermore, at least one swirl vane has a discharge flow angle between a tangent to its camber line at its trailing edge and the swirler axis that is monotonically increasing with increasing radial distance from the swirler axis. The invention also relates to a burner with such a swirler and a method of operating the burner.
