Abstract: A device 1, 100, 101, 102, 103 for converting heat into mechanical energy comprises a channel flow boiler 8, 22 adapted to heat a working fluid 13 to generate a liquid-gas mixture 33; an expansion device 9, 23 adapted to expand the liquid-gas mixture; and a movable element 10 arranged such that the expanding liquid-gas mixture to convert its internal and/or kinetic energy into mechanical work. Further, a method for converting heat into mechanical energy is disclosed, wherein the method comprises: heating S1 a working fluid for generating a liquid-gas mixture; expanding S2 the liquid-gas mixture; providing heat S3 to the liquid-gas mixture, and converting S4 the internal and/or kinetic energy of the liquid-gas mixture into mechanical energy associated with the movable element, wherein the method is operated as a thermodynamic cycle such that the expansion of the liquid-gas mixture is partially approximately isothermal.

Abstract: A desalination system (1) for producing a distillate from a feed liquid comprises: a steam raising device (2) having a liquid section (5) and a steam section (6) which are separated by a membrane system (7); a membrane distillation device (3) having a first steam section (11) and a liquid section (12) which are separated by a wall (14) and having a second steam sec­tion (13) which is separated from the liquid section (12) by a membrane system (15); and a heat exchange device (4) having a first liquid section (21) and a second liquid section (22) , which are separated by a wall (23). The steam raising device (2), the membrane distillation device (3) and the heat exchange de­vice (4) are implemented such that raw liquid fed into the second liquid section (22) of the heat exchanger-boiler device (4) is heated by brine liquid from the liquid section (6) of the steam raising device (2), such that permeate from the steam section (6) of the steam raising device (2) is condensed in the first steam section (11) of the membrane distillation device (3), thereby heating heated feed liquid from the heat exchange device (4). A method for operating a desalination system is also disclosed. Advantageously the desalination system operates at a reduced total thermal energy consumption.
