Heat transfer systems for maintaining a thermal balance between a gas turbine engine and heat generating accessory components of the engine are disclosed. In the embodiment illustrated, heat is removed from the cooling system 48 of an electrical generator 46 and is transferred to the fuel supply system 32 of the engine. In one detailed embodiment, the cooling system 48 is in direct heat transfer communication with the downstream portion 62 of the fuel supply system through a heat exchanger 76 and in indirect heat transfer communication with the upstream portion 60 of the fuel supply system through the fuel recirculation system 42.

A method for maintaining a thermal balance in a gas turbine engine operating at variable operating conditions which has a combustion section for burning a first portion of fuel to produce power and which has, a fuel system to supply fuel, the fuel system having a fuel at a temperature which is lower than the freezing point of water under certain operating conditions, wherein a fuel control having an inlet and an outlet for fuel is used to control the flow of fuel in the fuel system and wherein a generator for producing electrical power is driven by the engine, including the steps of: transferring heat from the electrical generator to the feel control by transferring heat from the electrical generator to a second portion of fuel in the fuel system to heat the fuel and to cool the electrical generator, flowing all of the heated fuel to the inlet of the fuel control and through the fuel control to the outlet of the fuel control to heat the fuel control to inhibit the formation of ice in the fuel control, and flowing an amount of fuel through the fuel control which is greater than the first portion of fuel and which is greater than the second portion of fuel.
