SYSTEM AND METHOD FOR OPERATING A COMBUSTOR WITH MULTIPLE LIQUID FUELS

The systems and methods presented herein are configured to transition from a first liquid fuel (38a) supplied to a combustor (14) of a gas turbine system (10) to a second liquid fuel (38b) supplied to the combustor (14) utilizing a fuel pump (42) configured to supply both fuels (38a, 38b) from the f...

Zusammenfassung:The systems and methods presented herein are configured to transition from a first liquid fuel (38a) supplied to a combustor (14) of a gas turbine system (10) to a second liquid fuel (38b) supplied to the combustor (14) utilizing a fuel pump (42) configured to supply both fuels (38a, 38b) from the fuel pump (42) during the transition without shutting down the gas turbine system (10). Through utilizing a fuel pump (42) and adjusting the operation of the fuel pump (42) during the transition, the additional costs, size, and operational complexity associated with multiple liquid fuel trains to facilitate operation of the gas turbine system (10) with multiple liquid fuels (38) may be avoided. The utilization of multiple liquid fuels (38) during operation of a gas turbine system (10) increases the operational flexibility of the gas turbine system (10) by enabling the utilization of varied liquid fuel sources and/or local liquid fuel sources during a steady-state operation, yet utilizing standardized fuel sources for startup or shutdown procedures.
