Abstract: The disclosure relates to monitoring a state of a physical passenger transport system. In an aspect, monitoring includes use of an updated digital double dataset that reproduces characterizing properties of components of the physical passenger transport system in an actual configuration of the passenger transport system after assembly and installation thereof in a building, in a machine-processable manner. At least one detection device is arranged in the physical passenger transport system, which detects a load profile which is transmitted to the updated digital double dataset. A set of rules is used to convert the load profile into modified characterizing properties of virtual components. Through the monitoring, changes and change trends on the components are tracked and evaluated using the updated digital double dataset by calculations and/or by static and dynamic simulations.

Abstract: A gas turbine installation includes at least one gas turbine. A transition piece may receive an exhaust gas from the gas turbine. The transition piece is an exhaust gas inlet part of a steam recovery part for a steam generator. The transition piece includes a chimney orifice for discharging the exhaust gas of the gas turbine.

Abstract: In a gas turbine installation, an exhaust gas chimney is formed by the transition piece of a steam generator, into which transition piece exhaust gas from the gas turbine can be introduced and can be discharged from the transition piece to a chimney orifice. The transition piece includes a component of the steam generator by which the exhaust gas can be supplied to a boiler region of the steam generator. The boiler region follows the transition piece in the direction of flow of the exhaust gas and has, arranged in it, at least one heating surface for the generation of steam.

Abstract: A flue-gas duct of a gas and steam-turbine plant is constructed in such a way that reliable sound absorption is ensured with especially simple provisions, even when using internally insulated duct pieces, in particular an internally insulated waste-heat boiler. The flue-gas duct includes a duct piece having a number of sound-absorber gates. At least one sound-absorber gate has a displacement nose disposed upstream thereof on the flue-gas side. A gas-switch module having a displaceable shut-off damper is disposed downstream of the duct piece which is constructed as a sound-absorber module, on the flue-gas side. The shut-off damper includes first and second substantially mutually perpendicularly oriented shut-off plates.

Abstract: A high degree efficiency in a gas turbine is assured by imposing a rifling swirl on the operating medium. The gas turbine has a turbine shaft and a number of burners that discharge into a combustion chamber configuration. The primary burner axis of each burner is tilted relative to the primary axis of the turbine shaft such that a defined swirl is created in the operating medium. An especially effective transfer of momentum from the flowing operating medium AM to a rotor blade configuration, particularly in full-load operation of the gas turbine, is thus attained without additional structural parts between the combustion chamber configuration and the rotor blade configuration.
