A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...
As with the tenders, the earlier L-1s would later be fitted with feedwater heaters, with the majority sporting Elesco bundle-type and Coffin internal feedwater heaters, though a handful of examples on the subsidiary Peoria & Eastern (as well as one on the NYC proper) had open-cycle Worthington SA type units, [3] and one each were furnished with ...
Some of the locomotives had a cylindrical Elesco feedwater heater ahead of the smoke stack, while others had a Worthington unit with its rectangular box in the same location. Only one Yellowstone was retired before dieselization took place on the Missabe; No. 237 was sold for scrap after a wreck. The rest of the 2-8-8-4s were retired between ...

[3] [b] Because of the Ps-4s' glamorous Virginian green and gold paint scheme, they were signified as the First Ladies of the Pacifics around the SOU system. [15] [16] Additionally, these locomotives were affectionally nicknamed the Harrison ...
In most cases, each passenger locomotive was fitted with a steam generator and a feedwater supply tank. The steam generator used some of the locomotive's diesel fuel supply for combustion . When a steam-generator–equipped locomotive was not available for a run, a so-called "heating car" fitted with one or two steam generators was inserted ...
British 9F 92024 with Crosti boiler, showing secondary smokebox door and side-mounted chimney Schematic diagram of a Franco–Crosti boiler with single feedwater heater. The Franco–Crosti boiler is a type of boiler used for steam locomotives.
The locomotives' marker lights, headlights, handrails, coupler lifting rods, cylinder head covers and back valve chambers were nickel-plated. Side rods were polished. The name of the train was painted in gold lettering on a blue nameboard that was mounted to the front of the locomotive smoke box just below the Elesco feedwater heater.
