摘要： PROBLEM TO BE SOLVED: To provide a method and system for operating a gas turbine system 100 having a compressor 110, a combustor 120 and a turbine 130 under partial load.
SOLUTION: The method and system may include steps of lowering a fuel flow rate to the combustor 120, extracting air from the compressor 110 so as to lower an air flow rate to the combustor 120 and returning the extracted air to the turbine 130 or a component of the gas turbine system 100 other than the combustor 120. Extracting air from the compressor 110 raises a combustion temperature in the combustor 120. Raising the combustion temperature maintains a combustion exhaust below a predetermined level, maintains stable combustion and increases turbine turndown values.

摘要： PROBLEM TO BE SOLVED: To provide a method, an apparatus and a system for igniting a wide range of turbine fuels.SOLUTION: In operating a gas turbine, there can be a difference between a desired heating value of the fuel and an actual needs of the fuel for the supplied fuel to be ignited. In one aspect, fuel parameters related to the molecular weight of the fuel such as specific gravity and pressure drop are determined. Ignitability of the fuel is calculated based on the fuel parameters and adjusted as necessary to bring the fuel's ignitability to a designed value. The fuel's ignitability can be calculated without actually igniting the fuel and also without direct knowledge of the fuel's calorific value or its composition.
