Figure 5-13. The Elliott TH expander is a single-stage hot gas expander with an axial inlet and vertical exhaust. The TH-line expanders range in horsepower from 4,000 to 50,000 and are of overhung rotor construction. The expander consists of four major components the inlet casing and its supports, the exhaust casing, the bearing housing and support system, and the rotor.

Fig ure 5-16. Casing and connections are designed to minimize distortions, prevent cracking, and allow relative movement during warmup and cool down. This view of the exhaust casing shows the stainless-steel expansion bellows. 

Figure 5-26. The exhaust casing fabrication is stainiess steei. in this picture, the bearing housing can be seen in the center of the casing. The inboard (diffuser) end of the iniet casing wiii be boited to the exhaust casing beiiows.

The exhaust casing shall be provided with at least one manway opening with gasketed cover for internal casing access by personnel. 

Figure 5-29. This view shows the conicai stainiess-steei backup piate ciosing the exhaust casing. The two fianged connections on the right are for the rotor biade viewing ports. The bearing housing is shieided from the backup piate by 3.5 in. (90 mm) of insuiation.

The most important applications of superalloys are in aircraft engines, marine vehicles, and stationary powder imits as turbine blades and vanes, and in sheet form for exhaust case assemblies and burner liners. Moreover, they are used in furnace combustion tubes, muffles, cracking and reformer tubes. 

In this study, simulation runs have been carried out to confirm if a given set of failures and/or disturbances can be considered as the root cause of the designated event H2O concentration in stream 25 is too high. Notice first that the undesirable Bed-I conditions listed in Table 14 can only be reached by triggering level-1 and/or level-2 component failures. To identify the corresponding root causes, all possible combinations of timer and valve failures were thus tested in a series of exhaustive case studies. The simulation results concerning the singlefailure cases are summarized in Table 15. Notice that the...

The alloy should be considered for applications in which other current low-expansion superalloys are presently used, such as compressor and exhaust casings, seals, and other gas turbine engine components. 

With this we have fully exhausted case (b) and begin on (a).
