Operation control method of gas turbine

Abstract

Abstract PURPOSE:To reduce the concentration of NOX in exhaust gas, by setting a proportion of pilot fuel to 25-50% when the operation only supplying pilot fuel is transferred to the operation supplying the pilot fuel mixing in main fuel. CONSTITUTION:A gas turbine provides the first fuel nozzle 2 supplying pilot fuel and the second fuel nozzle 5 supplying main fuel to a combustor 1. The turbine, when its operation is transferred from a 30-60% load only supplying pilot fuel to a 100% load, sets a proportion of the pilot fuel to mixed fuel to 25-50%. In this way, concentration of NOX in exhaust gas of the gas turbine can be reduced.
