Abstract:
1. A method for operating a gas-turbine engine, said method comprising the steps of: (a) providing a gas turbine that uses no air from outside atmosphere, (b) providing a gas-recycling means for recycling combustion gas from an outlet from said gas turbine to an inlet into said gas turbine, (c) providing a pressure-control means for controlling the pressure of recycled combustion gas and for discharging excess combustion gas into outside atmosphere, (d) providing a gas-cooling means for receiving, cooling and discharge of said combustion gas, (e) providing an oxygen-delivery means for adding oxygen to said combustion gas, (f) providing a fuel delivery means for adding fuel to said combustion gas, (g) providing a combustor, (h) providing a control means for controlling the operation of said gas-turbine engine in response to operator's demands and in accordance with a control program incorporated in said control means, (i) operating said gas-turbine engine in a gas-recycling mode by continuously performing a process that includes the steps of: (j) using said control means for control of operation of said gas-turbine engine, whereby said gas-turbine engine operates without receiving air from outside atmosphere, whereby said combustible mixture contains no nitrogen. whereby no nitrogen oxides are produced in said gas-turbine engine, and whereby harmful exhaust emissions are recycled back into said combustor and burned there.
