Definitions
- the present invention relates to the field of thermally loaded turbomachinery. It relates to a method for the determination of
- Residual life of a rotor of a thermally loaded turbomachine according to the preamble of claim 1. It further relates to an arrangement for carrying out this method.
- the rotor temperature in the inlet area of the turbine has not been measured directly. Instead, for example, the temperature at various points of the inner housing has been measured with thermocouples, and the corresponding temperature on the rotor has then been determined thereon based on a transfer function between the rotor and the housing. On the basis of these measurements, the voltage in the rotor and from it the remaining life have been derived.
- such a procedure has certain limits for fast transient processes, especially for machines operating at higher than usual steam temperatures. It should be noted, for example, that a surplus of 10% in the mechanical stress of the rotor (in combined power plants with two layers) can mean a reduction of the service life of 40%.
- JP-A-6200701 a method for determining the residual life of a rotor of a steam turbine is known in which the hardness of a high-temperature part of a new rotor is measured at periodic intervals. From this, a hardener reduction rate is calculated from which ultimately the life of the rotor is derived. This method also requires access to the stationary machine and is therefore complicated and inflexible.
- JP-A-7217407 a method and an apparatus for monitoring the life of a turbine are known, in which the surface temperature is measured on a housing and at an intermediate portion of the housing thickness and calculated from the difference, the thermal stresses and compared with calculated limits.
- the method is primarily suitable for static components (housings, valves, etc.). At best, this measurement allows conclusions to be drawn indirectly about the remaining service life of the rotor.
- JP-A-63117102 a method for determining the life of a steam turbine in a bore of the rotor is known, wherein the electrical resistance in a high temperature and a low temperature part of the rotor is measured with a displaceable in the bore electrical resistance sensor. From the difference of the resistors is then closed on the life of the high-temperature part.
- This differential measurement requires a complex built-in motion mechanism that is complicated and prone to failure in operation and requires significant additional costs for installation and maintenance. Presentation of the invention
- the method for determining the thermal stress occurring in a rotor can advantageously be implemented at least to a controlled startup of turbines, for example, in a steam turbine, the allowable steam parameters at the turbine inlet and the boiler outlet before and / or during startup the turbine is determined taking into account the allowable thermal stress in the highly loaded turbine parts.
- the measurement of the temperature on the rotor takes place without contact, by means of a pyrometer.
- Another embodiment of the method according to the invention is characterized in that the rotor is rotatably mounted about an axis and surrounded by a housing, that on the rotor in the axial direction one behind the other rows of blades are arranged, which are flowed through in the axial direction of the hot working gases in that the working gas is in an inlet area in the blading of the rotor is initiated, and that the temperature is measured at the rotor in the entrance area.
- the inlet region is formed by an inflow spiral formed annularly in the housing for radially introducing the hot working gas and by a deflection channel adjoining the inflow spiral for deflecting the incoming working gas from the radial to the axial direction, it is advantageous if the Temperature at the rotor in the deflection channel is measured shortly before the beginning of the blading.
- a further embodiment is characterized in that the measurement of the temperature of the rotor takes place from a stationary point on the surrounding housing, wherein in particular the measurement of the temperature of the rotor takes place directly from a point opposite the working gas channel on the surrounding housing.
- thermosensor is a pyrometer.
- the turbomachine has an inlet region for the introduction of the working gas into the blading of the rotor, wherein the pyrometer is aligned with a measuring region of the rotor lying in the inlet region.
- the temperature sensor or the pyrometer is arranged directly opposite the predetermined location or the measuring area of the rotor on the housing.
- the temperature sensor or the pyrometer is arranged stationary on the housing.
- Another embodiment of the arrangement according to the invention is characterized in that the temperature sensor or the pyrometer is connected to an evaluation unit, which is followed by a display device for displaying the remaining service life, wherein the evaluation unit in particular has a control output for controlling the operation of the turbomachine.
- FIG. 1 shows a longitudinal section through an exemplary inlet region of a steam turbine with a pyrometer for non-contact
- a pyrometer as an input element for a device for monitoring the thermal stress.
- the pyrometer is suitable for the non-contact measurement of the temperature at the surface of a solid body, whereby the thermal radiation emitted by the body is absorbed. In this way it is possible to directly read the temperature at the rotor where it is particularly critical, without having to carry out an indirect determination on the basis of a transfer function.
- Fig. 1 - starting from a steam turbine configuration, as disclosed for example in EP-A2-1 536 102 - reproduced the longitudinal section through the inlet region of such a steam turbine, in which arranged according to an embodiment of the invention, a pyrometer for measuring temperature is.
- a rotor 11 which is rotatable about an axis 22 and which terminates at one end in a rotor shaft 12.
- the rotor 11 is concentrically surrounded by an (inner) housing 13, wherein between the rotor 11 and the housing 13, a hot steam duct 26 is formed, in which a vanes 16 and blades 17 is arranged comprising blading.
- the vanes 16 are secured to the housing 13 while the blades 17 rotate with the rotor 11 about the axis 22.
- Hot steam is supplied to the turbine via a concentric Einströmspirale 14 formed in the housing 13, is deflected by a deflection channel 15 of the radial in an axial direction and enters axially into the hot steam duct 26 with the blading 16, 17, there to relax under work performance ,
- High temperatures prevail in the deflection channel 15, while the high thermal cycling occurs particularly strongly in the rotor area below the first row of races, wherein in a measuring area 18 the temperature of the rotor 11 is measured without contact by a pyrometer 20 fixed on the opposite side of the housing 13, on which the radiation beam 19 emanating from the measuring area 18 of the thermal or infrared radiation falls.
- the measuring area 18 with rotating rotor 11 corresponds to a different surface area of the rotor 11 at any time, depending on the angular position. If the temperature measurement by the pyrometer 20 is synchronized with the rotation of the rotor 11 in a suitable manner, the temperature measurement can always take place in the same surface area of the rotor 11. Otherwise, an integral measurement takes place via an annular, concentric surface section of the rotor 11.
- the (measured) temperature values recorded by the pyrometer 20 are transmitted via a supply line 21 to an evaluation unit 23 and evaluated there and converted into values of the thermal voltage and finally the remaining service life. These values can be displayed on a display device 24. But you can also have one
- Control output 25 are used to control the transient conditions of the steam turbine 10, for example, to optimize the remaining life of the rotor 11.
- the application of the invention can be planned in new steam turbines from the outset. But it is also conceivable to retrofit existing steam turbines with such a device. Likewise, it is conceivable to provide temperature measurements at several or other locations of the steam turbine in order to refine the determination of the remaining service life. Of course, the above statements are not limited to a steam turbine. Every other thermally loaded turbomachine is also part of this technical teaching.
