Document Type and Number:
Japanese Patent JP2509022
Kind Code:
B2
Abstract:
PURPOSE: To smoothly and surely perform also transfer or the like to 1-stage combustion control from 2-stage combustion control by performing stable control so that a device can well follow up relating to also load shutdown or the like, in the case of the gas turbine control device for 2-stage combustion operation.
CONSTITUTION: A fuel control valve 39 for setting a supply amount of total gas fuel is provided in a position in the upstream from a branch point of a supply fuel pipe 35. Primary/secondary side fuel distributing valves 40, 41 for setting distribution ratio of supply fuel are respectively provided in primary/ secondary side supply fuel pipes 36, 37. A valve position control means B1 of outputting a gas turbine speed.load controlling valve position control signal to the fuel control valve 39 to set a total gas fuel supplying opening is provided. A distribution ratio control means B2 for outputting a distribution ratio setting signal to the primary/secondary side fuel distribution valves to set each valve opening, based on a low NOx relating data corresponding to the valve position control signal output from the valve position control means, is provided.
