Abstract: The method for adjusting a natural gas temperature for a fuel supply line of a gas turbine engine includes measuring by infrared analysis the natural gas percentage content of methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), carbon dioxide (CO2), calculating the nitrogen (N2) percentage content as the complement to 100 of the measured percentage content of methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), carbon dioxide (CO2), calculating an index indicative of the natural gas energy content and adjusting the natural gas temperature on the basis of the index.

Abstract: A gas turbine and method for operating a gas turbine, includes a compressor, a combustor, a turbine and a cooling air cooling system having at least a first cooling air line going from a first bleed of the compressor to the turbine, and at least one second cooling air line at a downstream position of the compressor relative to the first cooling air line. A heat exchanger is arranged in the second cooling air line for cooling the extracted air of higher pressure. The heat exchanger is connected with an air inlet side of the compressor such that heat is transferred in order to heat up the inlet air of the compressor.
