Operating a turbine at baseload on cold fuel with hot fuel combustion hardware
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. A designated fuel split for avoiding combustion dynamics is scheduled (155) when a temperature...

| description | 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. A designated fuel split for avoiding combustion dynamics is scheduled (155) when a temperature for a gas fuel is below a designated value. Interlocks preventing mode transitions with cold fuel are disabled (130, 135). A determination (160) is made whether a modified wobbe index for the gas fuel is below an emissions compliant value. An alarm is activated (165) if the modified wobbe index is below the emissions compliant value to notify the operator of a potential emissions shift. |
