Abstract: A nozzle chamber assembly comprising an upper nozzle chamber resting on a lower nozzle chamber wherein the nozzle chambers are neither bolted nor pinned at their horizontal juncture but are held together by gravitational and pressure forces. A removable bolt which passes through the upper portion of the inner cylinder during assembly of the turbine and threads into the upper portion of the nozzle chamber to fasten the upper nozzle chamber in the upper portion of the inner cylinder during assembly and is removable once the inner cylinder is assembled. The inlet nozzles for the turbine and nozzle chambers are slidably received and sealed in a common bore which extends through the inner cylinder.

Abstract: A single-ended steam chest with an improved support assembly is disclosed. Inlet end flexible plates and outlet end flexible plates are affixed to the steam chest. The inlet end flexible plates are cooled while the outlet end flexible plates are heated thereby minimizing the rotation of the steam chest due to thermal expansion.
