Abstract

An expander is disclosed in which a working fluid (e.g. ethanol) is simultaneously utilized as a heat transfer medium and as a source of lubrication and cooling for gears, seals, and bearings within the expander. A small amount of mass flow of the working fluid, in its liquid state, can be diverted from a working fluid pump and into gear cases of the expander to be used as a cooling mechanism for the gears, lubricate the mesh between them, and lubricate the bearings and seals throughout the expander. Accordingly, the disclose expander and system eliminates the need for a dedicated lubrication circuit in which a substance other than the working fluid is used to lubricate the gears and bearings throughout the expander. Organic Rankine cycle (ORC) architectures that utilize a percentage of oil in the working fluid are also eliminated by the disclosed design.
