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.
Claims4
A method for adjusting a natural gas temperature for a fuel supply line of a gas turbine engine including a heat exchanger on the fuel supply line, the method comprising:
- measuring, by infrared analysis via a sensor, the natural gas percentage content of methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), carbon dioxide (CO2);
- calculating, via a controller, 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), and an index indicative of the natural gas energy content based on the measured and calculated percentage content of the natural gas;
- and
- driving actuators for the heat exchanger to adjust the natural gas temperature on the basis of the index.
