A method and apparatus for boosting the performance of gas turbine engines, pipelines, and other applications using gas turbine engine systems. A pressurizing device or other source is preferably used to deliver an intake air stream to the gas turbine engine at at least 2% above atmospheric pressure
A method and apparatus for boosting the performance of gas turbine engines, pipelines, and other applications using gas turbine engine systems. A pressurizing device or other source is preferably used to deliver an intake air stream to the gas turbine engine at at least 2% above atmospheric pressure. The pressurizing device of other source is preferably not mechanically driven by the gas turbine engine itself.
