Beschreibung
Zusammenfassung:An energy converter includes an electrical turbo-machine (101) for converting energy contained by vaporized working fluid into electrical energy, a feed pump (105) for pumping the working fluid in a condensed form to a vaporizer (115), a pre-feed pump (106) for pumping the condensed working fluid to the suction side of the feed pump, and an ejector-pump (108) for pumping the condensed working fluid to the suction side of the pre-feed pump. The energy converter can be based on for example the Organic Rankine Cycle. The feed pump is operated by the electrical turbo-machine, the pre-feed pump is operated by a separate motor (107), and the ejector-pump is operated by a part of the output flow of the pre-feed pump. The ejector-pump facilitates generating sufficient pre-supply pressure for the pre-feed pump during also a starting phase and other situations where the electrical turbo-machine and feed pump are not fully operating.
