Original Abstract Submitted

a gas turbine is configured such that: in a combustor receiving fuel and compressed air, a compressed air quantity supplied to a primary combustion field in the combustor when the rotation speed of a turbine shaft is a predetermined rotation speed is a quantity causing an equivalent ratio at the primary combustion field to be an equivalent ratio allowing misfire to be avoided in an operation state with a predetermined rotation speed and a predetermined load; fuel supply to the combustor is started when rotation of the turbine shaft is started up; a fuel quantity supplied to the combustor is controlled such that the rotation speed of the turbine shaft rises to the predetermined rotation speed, after ignition within the combustor; and increase in a magnitude of the load to the predetermined load is started before the rotation speed of the turbine shaft reaches the predetermined rotation speed.
