Abstract
Abstract In a gas turbine power plant for ship propulsion; exhaust gases are passed through regenerator (recuperator) units, forming part of the exhaust stack, in a heat-exchange relation with compressor discharge air prior to introduction of the compressor air into the combustion cycle. The regenerator units are uniquely supported in the ship''s hull; and, according to the present invention, provision is made for thermal expansion and contraction of the regenerator units, and dynamic loads due to ship roll and pitch.

A system for attaching a marine turbine powerplant regenerator having longitudinal and transverse axes to a ship''s hull, said system comprising: at least three support platforms, each support platform including a fixed plate having a substantially flat upper surface and a pair of spaced rails extending from said upper surface, said rails having elongated inner parallel surfaces which extend at right angles from said plate upper surface so as to form an elongated, generally U-shaped channel, at least two of said platforms being fixedly secured to the hull of said ship with said platform inner rail surfaces extending along one of said regenerator axes and at least one of said platforms being fixedly secured to the hull of said ship with said platform inner rail surfaces extending along the other of said regenerators axes; a regenerator footing for each support platform, each regenerator footing including a slidable plate having a substantially flat bottom surface and a pair of spaced rails secured to opposed sides of said slidable plate, said footing rails having outwardly facing elongated parallel surfaces extending at right angles to said footing plate bottom surface, each said footing fixedly secured to said regenerator so as to extend into the U-shaped channel of its respective support platform and sized so that said footing parallel surfaces are in close sliding relationship to said platform rail surfaces; each said footing plate formed with a plurality of apertures extending therethrough, a bushing for each said aperture, each said bushing having a stem portion and a flange portion at one end of said stem portion, the stem portion of each bushing extending through said footing plate and secured to said support plate, said stem and flange portions sized so that the flange extends beyond said aperture in close spaced relationship to the upper surface of said slidable plate, each said aperture being elongated along the axis of its respective parallel rail surfaces so as to permit relative movement along such axis between each support platform and its respective footing.
