The Reid-Ramsay steam turbine locomotive was a steam turbine locomotive with electric power transmission built in 1909/1910 according to plans by the British engineers Hugh Reid and David MacNab Ramsay .
history
Almost at the same time as Giuseppe Belluzzo , the two British engineers Reid and Ramsey also tested the applicability of the steam turbine as a drive for locomotives . In contrast to Belluzzo, the two British used electrical power transmission and steam condensation .
The vehicle carried out various test drives on the routes of the Caledonian Railway and the North British Railway . Due to the design chosen, the locomotive was relatively heavy in terms of performance, so that any fuel savings were largely consumed. At the beginning of the First World War in 1914, the experiments were stopped. The frame and bogies continued to be used on the Mac Leod-Reid steam turbine locomotive in 1923 .
Constructive features
The locomotive had a continuous frame with two bogies. The radiator for the condenser cooling water was located on the frame at the front above the first bogie, followed by the enclosed machinery above the center of the frame. The boiler was located above the rear bogie. The coal and water supplies were housed on both sides of the boiler.
The generated steam was fed to a Parsons turbine . This turbine operating at a constant 3000 min -1 a generator on. This supplied four series motors mounted on the drive axles with a voltage of 200 to 600 V.
The exhaust steam from the turbine was fed into the injection condenser . From there the condensation water was fed into the hot water expansion tank. The boiler was fed with water from the expansion tank via feed pumps. Excess water was fed back into the water tanks via the tubular air cooler. Water from these tanks served as injection water in the condenser. All water pumps were powered by auxiliary turbines.
Due to the steam condensation from the condensation locomotive, the steam was no longer blowing. A fan mounted in the cooler, driven by an auxiliary turbine, therefore supplied the fire box with the necessary fresh air.
