Also, turbines are run with high-quality steam : either superheated ( dry ) steam, or saturated steam with a high dryness fraction.
32.
Superheated steam and liquid water cannot coexist under thermodynamic equilibrium, as any additional heat simply evaporates more water and the steam will become saturated steam.
33.
The outside cylinders were inclined at 1 in 20 on the saturated steam engines, and on the superheated engines the incline was 1 in 40.
34.
In 1915, the South African Railways placed fifteen Class 14B saturated steam locomotives with a 4-8-2 Mountain type wheel arrangement in service.
35.
An M . L . S . multiple-valve regulator superheater header was fitted, arranged with the regulator valves located on its saturated steam side.
36.
The heated, pressurized water of the S1W reactor power plant was circulated through heat exchangers in order to generate high pressure saturated steam in a separate water loop.
37.
Whereas the first six examples were delivered as saturated steam compound locomotives, all of the remaining examples came into service as superheated machines with single stage steam expansion.
38.
The locomotive used saturated steam and had flat " D " type slide valves, placed above the cylinders and operated by Stephenson Link valve gear through rocker shafts.
39.
In a water tube boiler, the water is recirculated inside until the vapor pressure of the water overcomes the vapor pressure inside the stream drum and becomes saturated steam.
40.
The newer design of boilers initially used steam pressurized to, just like the older models, but used superheating to improve efficiency while the older boilers simply used saturated steam.
