Abstract: In order to improve the cooling of an air-cooled gas turbine in the partial load operating mode it is proposed to provide a connecting line between two cooling air lines with different pressure levels, which connecting line leads from the second cooling air line at a relative high pressure level to the first cooling air line at a relative low pressure level. In this context, a cooling device for cooling an auxiliary cooling air stream, flowing from the second cooling air line into the first cooling air line, and an adjustment element are arranged in the connecting line. In addition to a gas turbine, a method for operating such a gas turbine is the subject matter of the disclosure.

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.
