ABSTRACT:
The invention is concerned with an improved turbine shroud support assembly useful in a gas turbine engine which comprises a gasifier module within a case, a power output module fixedly detachably attachable to the case in position to receive exhaust gases exiting a combustor and passing via a gasifier turbine portion of said gasifier module to drive a power turbine having a turbine shroud about a plurality of blades thereof and thereby drive a shaft of said power output module and a heat exchanger arranged to receive compressed gas from a compressor of said gasifier module, heat the compressed gas therein and pass the resulting heated gas to the combustor and to receive the exhaust gases from the power turbine, cool the exhaust gases therein by transferring some of the heat thereof to the compressed gas and pass the resulting cooled exhaust gases to the exterior of the heat exchanger. The improved shroud support assembly comprises a plurality of struts supported by the power output module in fixed relation to the power turbine shaft and radially extending outwardly adjacent the power turbine, the struts supporting at an outer end thereof the turbine shroud in fixed closely spaced concentric relation about the plurality of turbine blades, the struts supporting at the outer end thereof an outer shroud which is positioned to direct flow of the exhaust gases from the blades of the power turbine to the heat exchanger.
