A 2-5 MW Supercritical CO2 Micro Tube Recuperator: Manufacturing, Testing, and Laser Weld Qualification
Project Innovation + Advantages:
International Mezzo Technologies will design, manufacture, and test a compact, nickel-based superalloy supercritical carbon dioxide (sCO2) recuperator (a type of heat exchanger). The recuperator will incorporate laser-welded micro tubes and function at 800°C (1,472°F) and 275 bar (3,989 psi). Currently, the cost of recuperators for power systems operating in these conditions is prohibitive. Laser welding micro tubes offers a low-cost approach to fabricating heat exchangers, which could increase the economic competitiveness of sCO2 power cycles. Mezzo’s program could provide a pathway to manufacture relatively inexpensive heat exchangers for high temperature-high pressure applications.
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.
