The Advanced Manufacturing Office has carried out a good amount of work with CHP systems that involve bottom up waste heat recovery conversion to power.
R&D on Waste Heat Recovery
- Waste Heat-to-Power in Small-Scale Industry using scroll expander for organic Rankine bottoming cycle. Medium-grade waste heat can be converted to electric power using a novel, scalable scroll expander having an isentropic expansion efficiency of 75% to 80% for a broad range of organic Rankine cycle boiler pressures, condensing temperatures, and speeds. Estimates suggest the system would generate net income in three years and provide national energy savings of 0.90 TBtu/year just for natural gas from coffee roasting applications alone.
- High Thermal Conductivity Polymer Composites for Low Cost Heat Exchangers to speed the development of plastic heat exchangers, researchers will create a database of selected properties for thermally conductive plastics. Heat exchangers manufactured from polymer composites would have several advantages over metal heat exchangers, including lower weight, improved corrosion resistance, and compared to the current manufacture of metal heat exchangers, increased energy productivity and lower greenhouse gas emissions.
