1. An apparatus for an aircraft, the apparatus comprising:
a fuel heat exchange system including a first fuel heat exchanger and a second fuel heat exchanger, wherein the second fuel heat exchanger receives a fuel to be injected into a combustor of an aircraft engine downstream of the first fuel heat exchanger;
an anti-ice heat exchanger;
a waste heat recovery heat exchanger; and
a conduit coupled to the fuel heat exchange system, the anti-ice heat exchanger, and the waste heat recovery heat exchanger, the conduit including a first portion, a second portion distinct from the first portion, and a third portion distinct from the first portion and the second portion, wherein the first portion of the conduit carries a first portion of a thermal transfer fluid from the waste heat recovery heat exchanger to the anti-ice heat exchanger in which the thermal transfer fluid supplies anti-ice heat to a portion of the aircraft, wherein the second portion of the conduit carries the first portion of the thermal transfer fluid from the anti-ice heat exchanger to the first fuel heat exchanger in which the first portion of the thermal transfer fluid supplies first heat to the fuel, wherein the third portion of the conduit carries a second portion of the thermal transfer fluid from the waste heat recovery heat exchanger to the second fuel heat exchanger in which the second portion of the thermal transfer fluid supplies second heat to the fuel, and wherein the third portion of the conduit maintains the second portion of the thermal transfer fluid separate from the first portion of the thermal transfer fluid that supplied anti-ice heat to the portion of the aircraft.
