PROBLEM TO BE SOLVED: To provide a method for optimizing reliability and efficiency by adjusting a temperature (preheating temperature) of a natural gas.SOLUTION: A method for adjusting a natural gas temperature for a fuel supply line 6 of a gas turbine engine 1, includes measuring natural gas percentage content of methane (CH), ethane (CH), propane (CH), butane (CH0) and carbon dioxide (CO) by infrared analysis, calculating nitrogen (N) percentage content as the complement to 100 of the measured percentage content of methane (CH), ethane (CH), propane (CH), butane (CH0) and carbon dioxide (CO), calculating an index indicating the natural gas energy content, and adjusting the natural gas temperature on the basis of the index. |
