ABSTRACT:
A low pressure turbine apparatus having a single casing member surrounding a rotatable member. The casing comprises six pieces which, when joined, provide an integrated single casing member. Suitable flex plates are provided to accommodate differential thermal expansion of the casing yet avoid thermal distortion of the apparatus. The stationary blading and inlet and extraction flow spaces are incorporated in a center section. Exhaust hood end sections with integral bearing housings are bolted to the center section through vertical joints. Axial brace pipes integral with the center section tie the end sections together and prevent movement of the bearings due to expansion of the higher temperatures in the inlet and extraction zones. Axial alignment of the stationary blading is provided at the center plane of the turbine by the use of integrally fabricated flex plates. The center section is insulated and exposed to atmospheric conditions. There is a separate condenser connection for each exhaust hood end section, and extraction pipe connections are made in an open atmospheric zone.
