NOVELTY - The system (10) has a chilled fluid system (40) for generating nitrogen as chilled fluid (46). An electromechanical machine i.e. generator (64), is cooled by heat exchange with the chilled fluid. The machine is provided with a rotor and a stator. A heat exchanger receives the chilled fluid, cools a heat transfer fluid by heat exchange with the chilled fluid, and circulates the heat transfer fluid through the machine. The fluid system comprises a reservoir for storing the chilled fluid. An electromechanical machine controller maintains the temperature of the machine below threshold temperature.    USE - Integrated gasification combined cycle (IGCC) power plant system. Can also be used for a hydroelectric power plant and chemical plant.    ADVANTAGE - The chilled fluid system can produce a primary product such as oxygen, and produce the chilled fluid as a byproduct e.g. nitrogen, as the chilled fluid to cool a component, thus improving the efficiency of the system by utilizing the energy used to generate the chilled fluid to cool a warm component such as generator, and by lowering the energy lost due to electrical resistance within the generator. The chilled fluid can be circulated to increase the heat removed from the generator to increase the generated output by removing or extending thermal limits in the windings. The chilled fluid allows the generator to be cooled with a smaller and/or less complex heat exchange system and reduces the frame size and complexity of the generator and increases the rated output of the generator with the same casing and frame. The chilled fluid can be circulated directly through the generator to reduce maintenance costs due to decreased corrosion and oxidation due to water leakage. The chilled fluid is directed from the generator to the gas turbine engine as diluent gas to decrease the energy used to heat the diluent gas prior to entering a combustor.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for using chilled fluid of an industrial plant to cool a portion of the industrial plant.
