ABSTRACT:
A steam temperature Ts and a casing air temperature Ta are measured by thermometers. The measurement results are taken into measuring devices and converted into electric signals. The electric signal is A/D converted by the measuring device and then, is sent to a control apparatus where a difference between both the temperature is calculated by a subtracter of a processor provided in the control apparatus. When an absolute value ΔT=|Ta−Ts of this difference is contained within 10° C. continuously ten times, a control signal is sent from a computing unit to a controller which is the control section, a pressure adjusting valve and the like are controlled and a cooling medium is switched to steam.
