ET 813

Two-Cylinder Steam Engine Module

Technical Description

The ET 813 forms a complete steam power plant with the matched steam generator ET 813.01 and the HM 365 Universal Drive and Brake Unit. Heat energy is initially converted into mechanical energy and then into electrical energy by the HM 365 operating as a dynamometer. The ET 813 experimental module contains a steam engine, a condenser and a condenser tank together with comprehensive instrumentation. The steam engine is an enclosed two-cylinder machine with 180° crank offset. It is of single action with plunger pistons. The condensate tank is designed as a cascaded tank and separates oil from the steam engine. The clean condensate is pumped back to the feed water tank of the steam generator.
A supply of cooling water is required for operation.
