Design optimization of small-scale ORC cycles for fluctuating heat source
Kim, Donghoi; Mocholí Montañés, Rubén; Riboldi, Luca; Nord, Lars Olof; Spale, Jan; Novotny, Vaclav (Chapter, 2022)Organic Rankine cycles (ORC) are efficient technologies for waste heat recovery (WHR) at low to mid temperatures. For the design of ORC power cycles, several thermodynamic parameters should be considered. A challenge related ... -
Intermediate pressure reboiling in geothermal flash plant for increased power production and more effective non-condensable gas abatement
Novotny, Vaclav; Vitvarova, Monika; Spale, Jan; Jakobsen, Jana Poplsteinova (Peer reviewed; Journal article, 2019)Non-condensable gases (NCG) in condensing geothermal flash plants have negative effects as they reduce heat transfer and thus deteriorate vacuum in condenser. Therefore, it is necessary to evacuate the condenser by vacuum ...
