Publication number: 20110016873Abstract: A fuel control method for a gas turbine with a combustor being formed of at least two groups of a pluralities of main nozzles for supplying fuel, and that supplies fuel from the main nozzles of all groups upon ignition of the combustor (S1), and supplies fuel from three main nozzles of a group A during subsequent acceleration of the gas turbine (S3). Because fuel is injected from a small number of the main nozzles during acceleration, the fuel flow rate per one main nozzle is increased, thereby increasing the fuel-air ratio (fuel flow rate/air flow rate) in a combustion region and improving the combustion characteristics. Accordingly, the generation of carbon monoxide and unburned hydrocarbon is reduced, whereby no bypass valve is required and manufacturing costs are reduced.Type: ApplicationFiled: July 1, 2009Publication date: January 27, 2011Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Sosuke Nakamura, Satoshi Tanimura, Shinji Akamatsu, Shinsuke Nakamura, Takashi Sonoda, Akihiko Saito, Makoto Kishi
