Abstract: A tool for installing or uninstalling a segment of an inner housing of a turbomachine. The turbomachine includes an outer housing, at least partially surrounding an inner housing and a rotor, concentrically arranged within the inner housing. The rotor is equipped with a number of rotor grooves. The inner housing is divided at an essentially horizontal split plane into an upper segment and a lower segment. The tool includes a first portion insertable into any of the rotor grooves, and furthermore includes a second portion disposed at a distance from the first portion. This second portion is connectable to the lower segment of the inner housing.

Abstract: The invention refers to a rotary flow machine having a rotor unit, rotating about a rotational axis, around which in at least one partial axial area a stationary inner housing (IH) is provided at a radial distance. The stationary inner housing (IH) can be divided up along the rotational axis in an upper and a lower inner housing half which adjoin each other along a horizontal split plane. The inner housing (IH) is surrounded in at least one axial section by an outer housing (OH) which can be divided up along the rotational axis in one upper and one lower outer housing half. Further a method for disassembling of a rotary flow machine is disclosed. The lower inner housing half provides support means which support the inner lower housing half on the lower outer housing half. The support means are detachably mounted at the lower inner housing half at least at two opposite support positions (P1, P2) relative to the rotational axis along the split plane.

Abstract: The method for removing an inner casing from a machine includes removing a top part of the outer casing, removing a top part of the inner casing, removing the bottom part of the inner casing, before removing the bottom part of the inner casing connecting the bottom part of the inner casing to the rotor, such that the bottom part of the inner casing is supported by the rotor, then rotating the rotor around the longitudinal axis to make the bottom part of the inner casing accessible.

Abstract: The method for removing an inner casing from a machine such as a turbine or compressor includes providing supports between the outer casing and the inner casing of the machine, removing a top part of the outer casing, then removing a top part of the inner casing, then connecting a ring sector to a bottom part of the inner casing to replace the removed top part of the inner casing, then rotating the reciprocally connected ring sector and bottom part of the inner casing around the longitudinal axis to make the bottom part of the inner casing accessible, then removing the bottom part of the inner casing, guiding the reciprocally connected ring sector and bottom part of the inner casing during rotation, to prevent movement along the longitudinal axis.

Abstract: A gas turbine is provided and includes a compressor, which via an air intake inducts and compresses air; a combustion chamber, in which a fuel is combusted using the compressed air, producing a hot gas; and a turbine, equipped with turbine blades, in which the hot gas is expanded, performing work. A first device is provided in order to cool turbine blades with compressed cooling air. The first device includes at least one separate compressor stage which produces compressed cooling air independently of the compressor.

Abstract: A vaporizer apparatus for vaporizing medical herbs and essences is described that uses an electrical power driven medium to vaporize the herbs and essences. The vaporizer apparatus has a heating element assembly mounted at an angle within an enclosure. The heating element assembly also includes an insulating shield which covers the heating element and which has a mating section for mating with a hand piece. The hand piece includes a vaporization chamber where herbs are packed, an inlet for connecting with the mating section of the shield, and an outlet for inhalation by a user. Methods for using the vaporizer apparatus is also discussed.

Abstract: A vaporizer apparatus for vaporizing medical herbs and essences is described that uses an electrical power driven medium to vaporize the herbs and essences. The vaporizer apparatus has a heating element assembly disposed within a shield. The shield is disposed within an opening of an enclosure. The shield protrudes from the opening at an angle and has a mating section for mating with a hand piece. The hand piece includes a vaporization chamber where herbs are packed, an inlet for connecting with the mating section of the shield, and an outlet for inhalation by a user. Methods for using the vaporizer apparatus is also discussed.
