METHOD FOR OPERATING A SUPPLY ASSEMBLY FOR SUPPLYING FUEL GAS AND INERT MEDIA TO A GAS TURBINE COMBUSTOR, SUCH SUPPLY ASSEMBLY AND A GAS TURBINE COMPRISING SUCH SUPPLY ASSEMBLY

摘要

A method for operating a supply assembly configured for supplying fuel gas and an inert purge media to a gas turbine combustor, the method including supplying fuel gas in a fuel gas circuit with an upper flow rate; reducing the fuel gas flow rate in the fuel gas circuit from the upper flow rate to a lower flow rate; stopping the supply of the fuel gas in the fuel gas circuit; and starting the supply of the inert purge media in the inert purge media circuit, wherein the starting is performed before the stopping to have a temporary parallel supply of fuel gas and of inert purge media to a fuel distribution system.
