DEVICE FOR DIAGNOSING COMBUSTION STATE OF GAS TURBINE

WIPO Patent Application WO/2017/094965

A1

Disclosed is a device for diagnosing a combustion state of a gas turbine. The device for diagnosing a combustion state of a gas turbine according to the present invention comprises: a combustion diagnosis tube in which one end thereof is provided with an opening to communicate with an inner space of a combustor for a gas turbine and the other end thereof is outwardly protruded; an infrared ray oscillator , formed to communicate with one side of the combustion diagnosis tube, for generating infrared rays into the combustion diagnosis tube; a dichroic optical mirror , formed in the combustion diagnosis tube , for performing a first reflection of only a part of the infrared rays into the combustor and transmitting the remainder thereof; an optical sensor formed on the other end of the combustion diagnosis tube in order to measure the intensity of a second reflected light, which is reflected by an inner reflection surface of the combustor , of the first reflected light which is reflected by the dichroic optical mirror; and a control unit , connected to the infrared oscillator and the optical sensor to control the same, for determining the amount of floating solids contained in flames in the combustor on the basis of the measured intensity of the second reflected light.
