Abstract: A recovery system includes a special organic Rankine cycle (SORC) system, an internal combustion system, a nitrogen generator and a gas-liquid separator. The SORC system includes a first stage heat exchanger (first HE), a plurality of second stage heat exchangers (second HE), a third stage heat exchanger (third HE), a turbo-expander, and at least one condenser. A recovery method, conducted in the recovery system, includes vaporizing a refrigerant, introducing the vaporized refrigerant to the turbo-expander to generate electricity, condensing the vaporized refrigerant in the at least one condenser, collecting nitrogen from the flue gas feed in the nitrogen generator, and collecting water from the flue gas feed in the gas-liquid separator. The refrigerant is vaporized by introducing the refrigerant through the first HE, second HE and third HE sequentially, and the flue gas feed through the third HE, second HE and first HE sequentially.

Abstract: A thermal management system for an aircraft comprises a first gas turbine engine, a first thermal bus, a first heat exchanger, and a chiller. The first thermal bus comprises a first heat transfer fluid, with the first heat transfer fluid being in fluid communication, in a closed loop flow sequence, between the first gas turbine engine, the first heat exchanger, and the chiller. Waste heat energy generated by the first gas turbine engine, is transferred to the first heat transfer fluid. The chiller is configured to lower a temperature of the first heat transfer fluid prior to the first heat transfer fluid being circulated through the gas turbine engine. The first heat exchanger is configured to transfer the waste heat energy from the first heat transfer fluid to a dissipation medium.

Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.
