ABSTRACT:
A small power plant utilizing waste heat wherein:
an intermediate heat transfer medium being thermally stable and capable of lubricating bearings is interposed between a heat source and a turbine operating medium;
heat of said intermediate heat transfer medium is taken off through a direct contact heat exchanger to change said turbine operating medium in phase from a liquid state to a gaseous state; and
a portion of said intermediate heat transfer medium is supplied as the lubricant for the bearings of the turbine and generator.
