Patent ID: 6877319

Claim:
A method of operating a combustion plant comprising at least a first gas turbine, a second turbine and a membrane reactor device which comprises a membrane filter device for separating oxygen from a gas mixture and a combustion space for the combustion of a fuel, which method comprises: that a gas mixture containing oxygen is supplied to the membrane reactor device and there goes through a separation in the membrane filter device, such that at least some oxygen is separated from the gas mixture such that an oxygen-depleted gas is obtained, that at least a part of said oxygen which has been separated from the gas mixture is used at said combustion in the combustion space, that said gas mixture is heated with the help of heat generated through said combustion in the combustion space, that at least a part of said heated oxygen-depleted gas, which has not gone through a combustion process, is used to run said first gas turbine, and that at least a part of the combustion gases which emanate from said combustion is used to run said second turbine.
