Title: Heat energy conversion system - has closed circuit, using ejectors to raise heat extraction temp.
Inventor: OLOFSSON GOESTA
IPC: F01K25/04
Filed: 1976-10-27
Abstract: System consists of a closed circuit embodying a driven unit (1), a residual heat extraction unit (2), a heat supply unit (3) and a pump (4) which raises the medium press. before it receives heat as well as ensuring circulation. After passing through the heat extraction unit (2) the medium enters a separation zone (15) whence the vapour only goes to the driven unit, the liquid flows along a separate loop to rejoin the vapour loop through a 2-stage ejector between the driven and the heat extraction units whose first stage has a central D-Laval nozzle (17) supplied with liquid at max. temp. and press. from the pump (4) and heat supply unit (3), raising the vapour temp. and press. so that temp. at entry to the heat extraction unit is above the min. value for the cycle. Second ejector stage has a series of peripheral nozzles (18), for liquid to mix, pref. progressively, with the vapour from the first stage, reducing the energy required for the conversion from velocity to press. which takes place in this zone.
