Innovative Waste Heat Recovery Systems and Improvements with Advanced Turbomachinery

The increasing cost of fuel and U.S. dependency on foreign fuel supplies has renewed interest in conserving energy and in generating electric power using otherwise wasted heat energy from prime mover processes. Such power generation systems are typically based on the thermodynamic Rankine cycle or the reverse Rankine cycles (i.e., a vapor compression, a.k.a. heat pumping). These systems can use water or organic-based (i.e., refrigerant-type) working fluids for Organic Rankine Cycle (ORC) power generation.
