Estimating the term…
A gas turbine is operated using a varying blend of a first fuel, preferably natural gas, and a second fuel that is hydrogen. The hydrogen concentration is varied depending on operating conditions in order to reduce emissions of CO and NOx, and/or to mitigate LBO. The fuel mixture is varied using a controller based on a combination of factors in a modular operation concept to address different issues according to relevant load limitations. A method of operating a gas turbine according to this modular operational concept is also provided.
A method for operating a gas turbine comprising:
A method for operating a gas turbine comprising:
A multi-stage gas turbine comprising a compressor, a first combustor in communication therewith, a first output turbine blade section, downstream of the first combustor and upstream of a second combustor in communication with a second output turbine blade section, the gas turbine further comprising first and second fuel supply valves, which provide fuel to first and second fuel blending systems, the first and second fuel blending systems are in communication with and provide first and second fuels to the first and second combustors, the first and second fuel supply valves are in communication with and are controlled by a controller.
