GERMAN STEAM TURBINE LOCOMOTIVES

(1928)

By Rob Arndt





THE KRUPP-ZOELLY TURBINE OF 1928- THE T18-1001





 


The 6-stage forward turbine developed 2000 hp at 6800rpm.
The reverse turbine had 3 stages.
Delivered to the LVA (Locomotive Testing Plant) in 1928.
Withdrawn after being hit by a bomb in 1940.

The casing was later removed for easier maintenance.
This was the usual fate of locomotive shrouds and casings.

The smokebox arrangements of the T18-1001 locomotive.

The diagram shows the feedwater heater wrapped around the inside of the smokebox,
and the draught fan, driven by a small steam turbine.

Note that there are actually two chimneys, the smaller one at the rear apparently
being used in conjunction with a steam blower set below its petticoat;
presumably this gave more draught than the fan,
and was used when raising steam had priority over economy.
This chimney would need to be closed off during normal fan operation,
and there appears to be a butterfly valve set in it just above boiler level.

The fan and its volute exit casing was offset from the center-line of the boiler.

The vertical thing mounted on the bottom of the smokebox appears to be a steam blower;
see above caption.


 






THE MAFFEI TURBINE OF 1928-THE T18-1002
 


 




The locomotive T18-1002 was delivered to the DRG in March 1929.
By 1934 the locomotive had covered 60,000 km.
Steam pressure was 323 lb/sq in.
In spite of the higher boiler pressure the Maffei was less economical than the Krupp.
It was withdrawn when damaged by bombing in 1943.
The boiler was used for safety-valve testing until it was scrapped in 1961.
