  • Patent number: 3950985
    Abstract: A method for monitoring the durability i.e. the service life of components of a thermal plant where, in functional relation to thermal as well as mechanical stresses, hours eqivalent to those of actual operation of such component at a given correlated mechanical and thermal stress value are counted. The correlated mechanical and thermal stress generated within the component and simulated by an equivalent electrical signal such as a voltage, is compared with a stress, likewise simulated by an electrical signal which at the relevant temperature of the component corresponds to a constant service life assigned by design specification, and the difference between the two electrical signals thus produced is correlated in a non-linear manner to a factor by which the period of actual operation is weighted and integrated, thus arriving at equivalent hours of operation.
