The present invention relates to a method for measuring a laminated stator core of electrical machines, in particular of large generators in maintenance. Disclosed is a method for measuring a stator core of an electrical machine, with the steps of winding at least one excitation coil around the stator core, applying a discontinuous voltage to the excitation coils to magnetically excite the stator core, and measuring a quantity of the magnetically excited stator core. Further, a corresponding measuring device is disclosed.

An axial flow turbine comprising a casing (14), a rotor (12) having an axial rotational axis (Z) and rotatably mounted into said casing (14), at least one set of a plurality of moving blades (16) supported by said rotor; and at least one diaphragm (18) having an outer ring (22), an inner ring (24), concentric to the outer ring, and a plurality of static blades (26) mounted therebetween, at least said outer ring (22) being split in an upper half (22a) and a lower half (22b) along a vertical joint plane (P). The turbine diaphragm (18) comprises an assembly system (30) for assembling the upper half (22a) to the lower half (22b) while allowing the upper half (22a) and the lower half (22b) to move axially relative to each other.

The method for separating carbon dioxide from flue gas comprises cooling the compressed flue gas in heat exchangers (3a, 3b) separating a carbon dioxide rich liquid from a carbon dioxide lean gas, supplying the carbon dioxide rich liquid and the carbon dioxide lean gas into a distillation column (8), separating in the distillation column (8) non-condensable gas from carbon dioxide liquid, heating the carbon dioxide liquid (CDL) at a cold side of a reboiler (14) generating a purified carbon dioxide liquid (PCDL), expanding the purified carbon dioxide liquid (PCDL) and supplying the expanded carbon dioxide liquid (ECDL) to the heat exchangers (3a, 3b) for cooling, supplying the expanded carbon dioxide liquid (ECDL) from the heat exchangers (3a, 3b) to a high pressure compressor (25) to generate a compressed carbon dioxide vapor (CCDV), supplying a part of the compressed carbon dioxide vapor (CCDV) from the high pressure compressor (25) to a warm side of the reboiler (14) generating a cooled carbon dioxide liquid (CCDL), expanding the cooled carbon dioxide liquid (CCDL) and passing the cooled carbon dioxide liquid (CCDL) through the heat exchangers (3a, 3b) for cooling. The purified carbon dioxide liquid (PCDL) and the cooled carbon dioxide liquid (CCDL) are directly forwarded to the at least a heat exchanger (3a, 3b).

A lime hydrator (20) integrated into a flue gas desulfurization system (18) or other industrial system is provided that provides an in-situ variable rate of cured hydrated lime production for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream. Also provided is a method of using a lime hydrator (20) integrated into a flue gas desulfurization system (18) or other industrial system to provide in-situ a variable production rate of cured hydrated lime for a variable supply rate of the in-situ produced cured hydrated lime for use within a flue gas stream as a moistened hydrated lime for a reduction of acid gas present in a flue gas stream.
