Wobbe control and enhanced operability through in-line fuel reforming

A method of regulating the Wobbe number of a multi-composition gas fuel supplied to one or more combustors of a gas turbine comprising: (a) providing a control system for regulating fuel and air flow to the one or more combustors; and (b) reforming a fraction of the gas fuel upstream of the one or m...

Beschreibung
Zusammenfassung:	A method of regulating the Wobbe number of a multi-composition gas fuel supplied to one or more combustors of a gas turbine comprising: (a) providing a control system for regulating fuel and air flow to the one or more combustors; and (b) reforming a fraction of the gas fuel upstream of the one or more combustors to form hydrogen and carbon monoxide to be supplied to the one or more combustors with a remaining fraction of the fuel; wherein the fraction of fuel reformed is adjusted to maintain the Wobbe number of the fuel supplied to the one or more combustors within a predetermined range.
