Life Time Monitoring
SR1 is a program system certified by an officially approved testing agency (the German TÜV) for the continuous monitoring of the stress of thick-walled components of power station boilers and turbines based on the procedure described in the German Technical Specifications for Steam Boilers (TRD) and DIN EN 12952-4. SR1 is an online system with a large number of powerfule features:
Determination of creep damage and low cycle fatigue
Online monitoring of the mode of operation of highly stressed components
Definition of a reasonable amount of inspection and identification of critical modes of operation by component ranking
Classification of operating pressure and temperature
Online calculation of the wall differential temperature for determining the stress from load cycling
Implementation without additional sensors
Use of the component configuration and calculated results for further processing
Where can you use it?
Potential ranges of application:
Plants with highly stressed, pressurized components like pipes, headers and other hollow parts as they are typically found in steam generators in power plants
Determination of the component lifetime consumption from the past in older plants in order to gain reserves and thus potentials for extending the operating time. This will also work if no SR1 lifetime monitoring or IT-based storage of data has been carried out so far
Backwards extrapolation from the beginning of the online monitoring. A reliable assessment of the history is possible already after online monitoring of ca. 5,000 hours of operation
SR1 continuous life time monitoring provides operators, authorized inspection agencies, and competent officials an important basis for assessment so that they can establish or extend the time intervals for required periodic inspections. Continuous life time monitoring makes it possible to choose the components that are subject to the highest stress for special attention during these inspections, making the inspections more precise and effective.
Start-up times can be reduced by selectively using existing off-loads, which SR1 can optimally identify. The power plant will be back on the network more quickly.
