The invention refers to a plant with a fuel system comprising a gas separation system (16), for separating at least a first fuel fraction (14) with high hydrocarbons, which has a higher concentration of high hydrocarbons than an incoming fuel gas (5). Ther...

Method for determining a temperature in a pressurized flow path of a gas turbine (10) comprising the steps of sending an acoustic signal from an acoustic signal emitting transducer (20, 21) across a section of the pressurized flow path, detecting the acous...

Reheat burner arrangement comprising a center body, an annular duct with a cross-section area, an intermediate fuel injection plane located along the center body and being actively connected to the cross section area of the annular duct, wherein the center...

The invention concerns a method of operating a gas turbine with staged and/or sequential combustion, in which the burners of a second stage or a second combustor are singularly and sequentially switched on during loading and switched off during de-loading....

Combined cycle efficiency can be improved by heating fuel in a gas turbine fuel line (42) in two stages (44,46) using (i) hot water from an HP economizer (32) of a heat recovery steam generator (HRSG) (16) in a second stage and (ii) hot water from an IP ec...

The station has compression devices (2-5) and heat exchanger devices (6-9) connected in series in an injection-pressure stage. The heat exchanger devices and expansion devices (13-16) connected in series in a delivery-pressure stage. A number of injection-...

The invention refers to a method for switching over a gas turbine plant from gaseous fuel (16, 20) to liquid fuel (18, 22) and vice-versa, wherein the gas turbine plant comprises a first combustor and a second combustor fed with the flue gases of the first...

Gas turbine (5) comprises a main combustion chamber (10), a cooling system for air-cooling at least the guide blades (26, 29) and the guide rings (28, 38) of different stages (25, 27) of the gas turbine and/or a main gas channel. A further combustion chamb...
