METHOD FOR STARTING GAS TURBINE POWER GENERATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine power generation apparatus that can be combusted and started while maintaining a pressure balance of the entire system stable even when difference of outer diameter (outer diameter of turbin wheel is lager than that of compressor impeller) between a compressor impeller (1) and a turbine wheel (6) is increased for capacity increase.

SOLUTION: A method includes: a contrifugal compressor for compressing air; a combustor for combusting the air compressed by the contrifugal compressor and fuel; and a radial flow turbine that is driven by a combustion gas generated in the combustor. The method combusts at a monitoring operation with a rotation speed lower than one where the pressure balance of the entire system is unstable, increases the temperature in a turbine inlet to a predetermined temperature where an operation inherent in the turbine can be performed and speedily increases the rotation speed while maintaining the pressure balance of the entire system stable.
