摘要： A premix burner, for example for a gas turbine, having a conical swirl generator (1) and a cylindrical mixing section (2) which follows it in the direction of flow, includes a high-pressure atomizer nozzle (10) with one or more fuel feed passages. The high-pressure atomizer nozzle (10) includes at least two outlet passages, through which liquid fuel enters the swirl generator (1), these passages being arranged off-center with respect to the longitudinal axis of the nozzle and being configured in such a way that the spray cone (11) of the fuel is oriented at an angle (β) with respect to the longitudinal axis of the swirl generator (1) which is smaller than the cone half-angle (α) of the swirl generator (1). The outlet passages in particular have an internal geometry with a conically narrowed section.

摘要： A premix burner consisting essentially of a swirl generator for a combustion air stream or another gaseous oxidizing medium and of conduits for injecting fuel into the swirl flow thus generated. As a result of a discontinuous cross-sectional widening at the transition to the combustion space, the swirl flow bursts open and a backflow bubble is formed, which serves for flame stabilization. For use under extreme thermal conditions, the burner front is provided with a heat shield which is fastened to a carrier structure in such a way as to allow, as unimpeded as possible, differential thermal expansions. The carrier structure is preferably provided with orifices, through which cooling air for the impact cooling of the heat shield flows. In a preferred variant, the fuel gas supply is designed as pipes which are led through orifices of the swirl generator without any fixed connection. As a result of this design, thermal stresses in the material of the burner are avoided as far as possible.

摘要： In a burner which consists of a swirl generator (100) on the oncoming-flow side, the flow (40) formed herein is passed smoothly into a mixing section (220). This is done with the aid of a transition geometry which is present at the start of the mixing tube (220) and consists of transition passages (201) which cover sectors of the end face of the mixing section (220), in accordance with the number of sectional bodies of the swirl generator (100), and run helically in the direction of flow. On the outflow side of these transition passages (201), prefilming bores (21) pass through the mixing section (220), which prefilming bores (21) initiate an increase in the flow velocity along the tube wall. Adjoining the mixing section (220) is a combustion chamber (30) in which a backflow zone (50) forms in the region of the jump in cross-section between mixing section (220) and combustion chamber (30).

摘要： A low pressure drop, highly efficient structured packing comprises sheet material formed into vertical preferably square channels containing vortex generators formed from the sheet material. The channels, while vertically linear, are periodically interrupted by the vortex generators providing tortuous fluid paths along the channels. The thus formed vortex generators form openings between adjacent channels providing fluid communication between and uniform flow within the different channels. The packing can be utilized in fluid mixing or those operations that require multiphase mass transfer, such as absorption or distillation. The addition of a catalyst makes the structure suitable for catalytic distillation. Turbulence is provided the fluids by the tortuous vertical path with low pressure drops transversely and vertically, with optimum liquid holdup.

摘要： In a method of compressing a gas, a compression which is simple to realize is achieved in that, in a first step, a foam (21) is formed from the gas and a liquid, in which foam (21) the sonic velocity is markedly lower than in the gas and in the liquid taken by themselves, in that, in a second step, the foam is directed at supersonic velocity through a nozzle (19, 20) and the gas located in the foam is thereby compressed, and in that, in a third step, the compressed gas and the liquid are separated from one another behind the nozzle (19, 20).

摘要： In order to improve the combustion of the liquid fuel (4) in such a burner (1) without influencing that of the gaseous fuel (7), the liquid fuel (4) is directed at high flow and swirl velocity into the settling chamber (13) of the airblast nozzle (2). Then the flow and swirl velocity is reduced and a thin fluid film is formed on the prefilming lip (15). The blast air (15) is directed with a quantity ratio of less than 1:1 to the liquid fuel (4) into the airblast nozzle (2) and separates small fuel droplets at the tip (27) of the prefilming lip (15).In a double-cone burner (1), the combustion mixture (28) is injected against the swirl of its main air flow (8) and at a spray angle (26) of less than or equal to 30.degree..
