Abstract:
1. A method for operating a combustor, said method comprising: supplying a predetermined amount of a first gaseous fuel to a blending device, wherein the first gaseous fuel has a first Modified Wobbe Index (MWI) and a first fuel reactivity; supplying a predetermined amount of a second gaseous fuel to the blending device, wherein the second gaseous fuel has a second MWI and a second fuel reactivity, wherein the first MWI is greater than approximately two times the second MWI and the second fuel reactivity is higher than the first fuel reactivity; regulating a flow of each of the first and second gaseous fuels to the blending device to form a blended gaseous fuel having a third MWI; and supplying the blended gaseous fuel from the blending device to an injector of the combustor via a single main fuel line.
