Method and device for controlling combustors for gasturbine

摘要

A method for controlling a plurality of combustors supplying a pressurized gas to a gas turbine, with each of the combustors including a first air supply for supplying a combustion air into the combustor and a second air supply for adjusting an amount of air supplied into the combustor to change a combustion condition in the combustor. The method comprises the steps of measuring the combustion condition of each of the combustors, measuring a difference between the measured combustion condition of each of the combustors and a desired combustion condition, and changing a rate of the amount of air supplied into the combustor by the second air supply means in relation to an amount of combustion air supplied into the combustor by the first air supply in each of the combustors according to the measured difference of each of the combustors to change the combustion condition of each of the combustors so that the combustion conditions of the combustors are changed to the desired combustion condition.
