ABSTRACT:
A steam turbine construction wherein the turbine rotor shafting is mounted in bearing means located in the end walls of the turbine housing and wherein the bearings are lubricated with water condensed from the working steam supplied to the turbine. The lubricant flows in a re-circulating system tapped from the condensate-return line leading back to the boiler from the condenser after the turbine has been started and is supplying power, and an auxiliary supply of lubricant water is taken from a reserve gravity flow tank to supply water to the bearings during the starting and stopping runs of the turbine.
