Abstract

PURPOSE: To prevent the lowering of the stress of clamping bolts, by feeding steam for cooling extracted from a high pressure portion by means of a steam distributor to the surroundings of each flange clamping bolt, by uniformly cooling the bolts, by recovering the steam to a steam storage instrument and by discharging the steam to an intermediate pressure inlet portion.
