Low-Cost Glass Ceramic-Matrix Composite Heat Exchanger
Technology Description:
UTRC will develop a high temperature, high strength, low cost glass-ceramic matrix composite heat exchanger capable of a long operational life in a range of harsh environments with temperatures and pressures as high as 1100°C (2012°F) and 250 bar (3626 psi). UTRC designed its Counterflow Honeycomb Heat Exchanger (CH-HX) configuration with an oxidation-resistant material developed initially for gas turbine applications. Its core feature is a joint-free, 3D-woven assembly of webbed tubes and cylindrical shapes to reduce stress and simplify manufacturing. The CH-HX is devoid of nearly all secondary surfaces, which increases thermodynamic performance. Its light weight, reduced volume, and high temperature robustness could enable its use in applications that benefit from high-efficiency supercritical CO2 power cycles.
Potential Impact:
HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.
Security:
High performance, efficient heat exchangers would increase industrial productivity, supporting domestic industries. The developed manufacturing techniques for high temperature materials could strengthen U.S. leadership in advanced manufacturing.
