Abstract

A turbine system which includes a reheater upstream from a low pressure turbine which is subject to corrosive salt depositions from the steam. Conductance probes are inserted at predetermined positions within the low pressure turbine and based on the conductance signals the reheat temperature or load is varied so as to move the corrosive salt deposition zone away from a rotating blade stage of the low pressure turbine.
