Abstract:
Clean Cycle™, from GE Energy, adapts Organic Rankine Cycle (ORC) technology for the vast majority of smaller-scale heat-wasting processes. Clean Cycle takes waste heat from sources as low as 250°F (121°C) and transforms it into 125 kW of electricity for the renewable and distributed energy segments. An integrated Power Module (IPM) is the heart of the Clean Cycle system and houses the high speed turbine and generator. Magnetic bearings that support the turbine and rotor facilitate the shaft spinning in a magnetic field rather than riding on a mechanical bearing. The bearings require no lubrication systems, and the entire generator and turbine are hermetically sealed so external seals are not required, either. Clean Cycle’s Power Electronics convert the raw power generated at the IPM to usable electricity at the exact same frequency and voltage as the grid to which the IPM is attached -- without gearboxes or other mechanical means. The power generated has a constant power factor of 1, so costly capacitors are not needed. Clean Cycle can operate in small spaces, be moved from site to site, and accommodate a broad range of facilities, including factories, foundries and cement plants. To utilize Clean Cycle, waste heat must be exclusively available, with no diversion to other purposes such as heating water. The number of engines determines the type of installation. Customers have the option of installing a collection of smaller engines to combine their accumulated waste heat.
