A method and algorithm are provided to operate a gas turbine at baseload in an emission compliant capable mode to avoid combustion dynamics while operating with cold fuel and hot fuel combustion hardware. The method includes performing a gas turbine operational sequence such as a startup to an emission compliant capable mode. A gas fuel temperature is measured. The gas turbine is operated in the emissions compliant capable mode according to a designated fuel split for avoiding combustion dynamics when a temperature for a gas fuel is below a designated value. A determination is made whether a modified wobbe index for the gas fuel is below an emissions compliant value. An alarm is activated if the modified wobbe index is below the emissions compliant value to notify the operator of a potential emissions shift.
A method to operate a gas turbine at high loads in an emission compliant capable mode to avoid combustion dynamics while operating with cold fuel and hot fuel combustion hardware, comprising:
An algorithm whose technical effect is to allow a gas turbine operating under an emission compliant capable mode at high loads to avoid combustion dynamics while operating with cold gas fuel and hot fuel combustion hardware, comprising:
A gas turbine control system adapted to allow a gas turbine with an emission compliant capable mode to avoid combustion dynamics while operating with cold fuel and hot fuel combustion hardware, comprising:
