Document Type and Number:
Japanese Patent JP2022105225
Kind Code:
A
Abstract:
To provide a combustor for a gas turbine that suppresses combustion vibration by controlling generation of a large vortex, and combustion control method for the combustor for the gas turbine.SOLUTION: A combustor for a gas turbine having a cylindrical duct part inside of which serves as a combustion chamber and a supply device supplying mixed gas from an inlet of the combustion chamber into the combustion chamber includes: a pressure sensor detecting pressure in the duct part and outputting a pressure signal; a DBD plasma actuator disposed at the inlet of the combustion chamber and having a pair of electrodes; and a drive circuit for intermittently driving the DBD plasma actuator by transmitting a drive signal to the electrodes on the basis of the pressure signal from the pressure sensor.SELECTED DRAWING: Figure 7
