Abstract: A wet scrubber (1) useful for cleaning a process gas comprises at least a first spray level system (20) and a second spray level system (26) arranged vertically above the first spray level system (20) in a wet scrubber tower (2). The first spray level system (20) comprises at least one gas-liquid contacting plate (38) which is operative for deflecting absorption liquid, that has been atomized by means of the second spray level system (26) and flowing downward in the wet scrubber tower (2), so deflected absorption liquid (AL) may contact process gas (F) contacted by absorption liquid atomized by the first spray level system (20).

Abstract: The invention refers to a blade of a rotary flow machine including an airfoil having a suction surface and a pressure surface joining each other along a trailing and a leading edge. A radially outward directed airfoil tip and a radially inward directed end joining an inner platform connect the airfoil to a shank at a radial end of the airfoil and providing, at least one shank pocket radially encircled by an axially extending portion of the platform. At least one radially extending rim extends from the trailing edge side of the shank and has an essentially radially orientated first slot for receiving a seal. A mount extends radially inwardly from said shank pocket. The first slot has a first aperture on a shank surface orientated in an axial direction.

Abstract: A tool for assembly of an inner enclosure of a generator or a machine comprises a first part and a second part. The first part comprises a plate with one edge constructed to form a first half-ring. The second part comprises a second half-ring corresponding to the first half-ring of the first part. Upon assembly of the first part and the second part, the first half-ring and the second half-ring form a full-ring to encompass a shaft of the generator or the machine and to connect to an inner enclosure of the generator or the machine.

Abstract: The invention relates to an assembly of modules for an electrical circuit comprising: a module support for at least two modules and at least two modules, each module comprising two complementary connectable sub-modules. The module support comprises for each sub-module at least an alignment member adapted to individually align the sub-module during its installation on the module support in such way to connect it to complementary sub-module already installed on the module support to form one of the modules. The invention also relates on a module support, a module and a Flexible Alternative Current Transmission Systems.

Abstract: The invention relates to a mixing arrangement for mixing a fuel with a stream of oxygen containing gas flowing along an axis in an axial channel, especially in the second combustor of a gas turbine with sequential combustion. The mixing is improved and the mixing length reduced by said mixing arrangement comprising an injector with at least one injector ring, which is passed by said stream of gas inside and outside.

Abstract: The disclosure relates to a method for determining a temperature in a pressurized flow path of a gas turbine comprising the steps of sending an acoustic signal from an acoustic signal emitting transducer across a section of the pressurized flow path, detecting the acoustic signal with a receiving transducer, measuring the time needed by the acoustic signal to travel from the acoustic signal emitting transducer to the receiving transducer, calculating the speed of sound, and calculating the temperature as a function of the speed of sound, the heat capacity ratio (□) and a specific gas constant (Rspec) of the gas flowing in the pressurized flow path.Besides the method, a gas turbine with a processor and transducers arranged to carry out such a method is disclosed.

Abstract: The invention refers to a gas turbine blade including an airfoil extending in radial direction from a blade root to a blade tip, defining a span ranging from 0% at the blade root to 100% at the blade tip, and extending in axial direction from a leading edge to a trailing edge, which limit a chord with an axial chord length defined by an axial length of a straight line connecting the leading edge and trailing edge of the airfoil depending on the span. The axial chord length increases at least from 80% span to 100% span.
