METHOD FOR STARTING A GAS TURBINE

摘要

A method of starting a gas turbine is provided, comprising the step of providing an apparatus for regulating the flow of fuel in a gas turbine, the apparatus comprising a main line connecting a fuel source to a nozzle array; and an auxiliary line connecting the fuel source to the nozzle array. The method further comprises the steps of keeping the main line sealed while increasing the auxiliary line fuel flow rate; firing the gas turbine while keeping the main line sealed; and after the combustion has started in the gas turbine, opening the main line for increasing the main line fuel flow rate; wherein the auxiliary line maximum flow rate is less than the main line maximum flow rate.
