Abstract:
A condenser augmentation device for a steam-powered system, comprising:a boiler, said boiler including a condensate inlet, a pressure vessel, a means for heating said pressure vessel, means for controlling said heating, means for providing a steady flow of steam from said boiler, and a steam outlet;a steam-driven device, said device including a steam inlet and an exhaust outlet, said steam inlet being connected to the steam outlet of the boiler;said exhaust outlet being of a first predetermined cross-section;a choke, said choke having an inlet end, an outlet end, a second cross-section and being attached at its inlet end to the exhaust outlet of the steam-driven device;a condensing line, said condensing line having an inlet end, an outlet end, a third predetermined cross-section and being connected at its inlet end to the outlet end of the choke and being connected at its outlet end to the condensate inlet of the boiler;said third predetermined cross-section being larger than said second cross-section;a working fluid, said working fluid being disposed within the pressure vessel of said boiler and capable of being heated to a vapor stage therein and being capable of being converted to a liquid condensate in said condensing line after powering said steam-driven device and passing through said choke;said choke including means of reducing the second cross-section to a size substantially smaller than said first and third pre-determined cross-sections;said choke causing the working fluid vapor to cool and to condense by flowing through said smaller second cross-section at a reduced volume but at a rate of speed to expand the vapor in said condensing line;said means of reducing the second cross-section to a size substantially smaller than the first and third pre-determined cross-sections further comprising:an adjustable choke plate, said adjustable choke plate being disposed within said choke between said inlet end and said outlet end and capable of varying said second cross-section between a first size and a second size.
