Title:
SMALL SCALE COGENERATION SYSTEM FOR PRODUCING HEAT AND ELECTRICAL POWER
Document Type and Number:
WIPO Patent Application WO2001055561
Kind Code:
A9
Abstract:
A small-scale, space-heating and electrical power co-generation system includes a heater (104) and a pump (136) for supplying high-pressure water to the heater (104). Within the heater, the high-pressure water is heated to at or near its saturation or boiling point so as to produce both vapor (e.g. steam) and liquid (e.g., water) fractions. This high pressure, two-phase mixture is then provided to an expander (120) which expands the two-phase mixture to a lower pressure and, in the process, produces mechanical energy. The expander (120) is coupled to an electrical generator (122) so that the extracted mechanical energy can be used to drive the generator and thus produce electrical power. The fluid exiting the expander is then provided to a condenser (126). A space heating fluid (e.g., air or a separate water supply) is brought into proximity with the condenser so that it may be heated.
