SECTIONED GAS TURBINE ENGINE DRIVEN BY SCO2 CYCLE

摘要

An apparatus, system, and method for a gas turbine engine (10, 100, 200, 300) may include a sectioned heat exchanger (402). A heat exchanger (402) may include an inlet manifold (414) configured to receive a working fluid. A plurality of circuits (404a-c) including at least first and second circuits (404a, 404b, 404c) configured to transfer heat with respect to the working fluid. Each of the circuits (404a-c) may have a circuit inlet valve (418), a circuit heat exchange channel, and a circuit outlet valve (420). The heat exchanger (402) may further include an outlet manifold (416) configured to pass the working fluid to an outlet (410). The heat exchanger (402) may include a first sensor (422, 424) configured to measure of first parameter of the first circuit (404a) and a second sensor (422, 424) configured to measure a second parameter of at least one of the outlet (410) and the second circuit (404b, 404c). A controller (426) may be configured to selectively isolate at least one of the plurality of circuits (404a-c) based on a pressure difference between the first and second parameters.
