Heat Exchanger for Gas Turbine Exhaust Waste Heat Recovery
Several prior efforts by the U.S. Navy to recover waste heat have shown promise, but various reliability issues were encountered associated with the exhaust gas heat exchanger. This heat exchanger must be able to withstand the high temperature corrosive gas turbine exhaust, endure thermal transients and shock, and withstand the high pressures of the bottoming cycle working fluid that flows through the heat exchanger as it picks up energy from that gas turbine exhaust …
