Initial introduction of temperature measurements are already mentioned in Chapter I
, Clauses 3.1
, and Clauses 1.2
, and 1.5
of this chapter. Various measuring points in the power plant (typical value of a 250 MW plant) are given in chart form (see Table IV/3-1
) along with operating/ MCR values and instrument ranges. Normally the calibrated ranges are selected so that the operating or MCR value is ∼67% (but normally not beyond 75%) of the full range. There may be some cases where the operating or MCR value is closer to the calibrated range.
