56,209 ABSTRACT OF THE DISCLOSURE A mounting ring is provided which adapts an oversized exhaust flow guide to the existing inner cylinder of a steam turbine. The mounting ring is comprised of six arcuate segments which allow the mounting ring to be radially installed into a groove, machined in the outer diameter of the inner cylinder, despite the presence of lugs which preclude axial installation. The mounting ring and exhaust flow guide form a moisture removal gap just upstream of the tips of the last row rotating blades. Arcuate filler segments are installed in the vicinity of the horizontal joint to create a uniform moisture removal gap around the circumference of the steam flow path. The mounting ring creates an access space above the horizontal joint flanges in the cover half of the inner cylinder for installation of the horizontal joint bolts.
