Waste-Heat-to-Power Applications on the Rise | Power Electronics

22/6/2018 · Most of today's waste-heat power systems employ a liquid working fluid that's pumped to an elevated pressure before entering a heat-recovery boiler. The pressurized fluid is vaporized using energy captured from waste heat, and then expanded to lower temperature and pressure in a turbine, generating mechanical power that drives an ac alternator.
