20090293596 | Method for Inspecting a Turbine Installation and Corresponding Device - The invention relates to a method for inspecting especially a gas turbine installation or steam turbine installation. According to said method, an actual condition of a component of the turbine installation is determined using a suitable system, the determined actual condition is compared with a predetermined desired condition of the component, and the result of comparison between the actual condition and the desired condition is used to determine whether an overall inspection of the turbine installation is required. The component is a guide vane whose angular position in relation to the direction of influx is the actual condition to be determined. The actual condition is determined by means of an imaging device. The invention also relates to a turbine inspection system for carrying out the method. | 12-03-2009 |

20100206058 | Method for determining the lifecycle of a power station component - A method for determining the life cycle of a power station component is provided. The method includes the following steps: definition of a first characteristic for the life cycle of a power station component at a constant output, definition of a second characteristic for the life cycle of the power station component at a variable output, definition of a first equivalence rule as a function from an actual time parameter, definition of a second equivalence rule wherein the pre-defined operation of the power station component at the variable output in accordance with a plurality of second characteristics is depicted, determination of the numbers of first and second characteristics that are generated during the actual operation of the power station, determination of the sum of the numbers of first and second characteristics, and assessment of the life cycle of the power station component using the determined sum. | 08-19-2010 |
20120285227 | METHOD FOR DETERMINING STEAMPATH EFFICIENCY OF A STEAM TURBINE SECTION WITH INTERNAL LEAKAGE - A method of more accurately measuring steam turbine efficiency is disclosed in which the sealing steam in the steam turbine is re-routed so that a more accurate measure of steam turbine efficiency can be made. Some of the steam entering a turbine goes into the turbine's end pack and then mixes with the steam that goes through the turbine. Piping is added from one of the end pack line's to the condenser. This added line has a valve, pressure, temperature and flow measuring devices. As the valve is opened, the amount of flow going to the end pack line allowing the end pack steam mix with the steam that goes through the turbine is reduced. As the flow in this line is reduced the measured temperature at the turbine exhaust will also decrease. The amount that the valve is opened is increased until either the exhaust temperature has reached a minimum, or the enthalpy in the pipe changes from the initial enthalpy. | 11-15-2012 |
20130233064 | METHOD OF MEASURING STEAM TURBINE, MEASURING DEVICE, AND METHOD OF MANUFACTURING STEAM TURBINE - A method of measuring a steam turbine according to an embodiment has: installing a measuring device into the inside of the steam turbine through an inspection hole or a manhole of the steam turbine or an inspection hole or a manhole of a condenser connected to the steam turbine, when the steam turbine is halted; and measuring a position and a dimension of an axial key or a center key of the steam turbine by using the measuring device, without opening a turbine casing of the steam turbine. | 09-12-2013 |
20140026650 | METHOD FOR MONITORING MACHINES WITH ROTATING SHAFTS - The invention relates to a method for detecting rubbing and/or contact points on machines with rotating parts. The rotating parts form an electrical coaxial system with respect to the stationary parts of such a machine, in which system electrical voltage pulses are propagated at a characteristic speed because of the small distance between the rotating and the stationary part. Short electrical voltage pulses and/or continuous alternating voltage signals are applied between the rotating part and the stationary part, an electrical connection occurring between the rotating and the stationary part at a rubbing and/or contact point. In order to locate this rubbing and/or contact point as a point of electrical discontinuity, the period of time until the reflected pulses arrive is measured along the path of propagation of the electrical voltage pulses and/or of the continuous alternating voltage signals. | 01-30-2014 |
