Abstract
The invention relates to a method for operating a steam power plant, comprising a steam engine which is operated with a vaporous working medium, an evaporator for evaporating the working medium; a condenser for liquefying the working medium and a reservoir for the working medium. The invention is characterized in that a lubricant sump in a housing of the steam engine is heated to a temperature above the evaporating temperature of the working medium by means of a heating device during the starting phase of the steam engine.

A method for operating a steam power plant, including a steam engine, which is operated with a vaporous working medium, an evaporator for evaporating the working medium;
- a condenser for liquefying the working medium and a reservoir for the working medium,
- characterised in that a lubricant sump in a housing of the steam engine is heated to a temperature above the evaporating temperature of the working medium by means of a heating device during the starting phase of the steam engine.
A steam engine including:
- a steam engine housing with a lubricant sump enclosed inside the steam engine housing;
- an expansion chamber for a vaporous working medium driving the steam engine, which is situated inside the steam engine housing;
- characterised in that
- a housing ventilation unit with an oil separator is fitted on the steam engine housing and a heating device is associated with the lubricant sump, that brings the lubricant sump to a temperature above the evaporating temperature of the working medium.
