摘要： A method of cooling a gas fueled engine driven intercooled air compressor comprises providing the intercooled air compressor, a gearbox, and the gas fueled engine. The method includes flowing a liquid coolant from a liquid coolant supply to each of the gearbox and an intercooler of the intercooled air compressor. The method comprises recombining the liquid coolant after the gearbox and the intercooler. The method includes directing the recombined liquid coolant via multiple paths to cool the gas fueled engine. The method comprises recombining the liquid coolant after the liquid coolant has passed through the multiple paths.

摘要： Systems and methods to control gas turbine firing temperatures during air injection. A method of achieving a desired firing temperature of a gas turbine engine during air injection comprises injecting compressed air into the gas turbine engine using an external source. The external source includes a compressor and a recuperator. The method comprises using a controller of the gas turbine engine to: (a) determine an air injection exhaust bias gain using an inlet temperature of the gas turbine engine; (b) calculate, based on the determined air injection exhaust bias gain and a flow rate of the injected compressed air, an air injection exhaust curve bias; and (c) change a fuel flow of the gas turbine engine by adding the air injection exhaust curve bias to an existing exhaust curve of the gas turbine engine to thereby achieve the desired firing temperature during air injection.
