Abstract:
(EN) 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.
(FR) L'invention concerne un dispositif de diagnostic d'un état de combustion d'une turbine à gaz. Le dispositif de diagnostic d'un état de combustion d'une turbine à gaz selon la présente invention comprend : un tube de diagnostic de combustion dont une extrémité comprend une ouverture pour communiquer avec un espace interne d'une chambre de combustion pour une turbine à gaz et dont l'autre extrémité fait saillie vers l'extérieur ; un oscillateur à rayons infrarouges, formé de façon à communiquer avec un côté du tube de diagnostic de combustion pour générer des rayons infrarouges dans le tube de diagnostic de combustion ; un miroir optique dichroïque, formé dans le tube de diagnostic de combustion, pour effectuer une première réflexion de seulement une partie des rayons infrarouges dans la chambre de combustion et transmettre le reste de ces derniers ; un capteur optique formée sur l'autre extrémité du tube de diagnostic de combustion de façon à mesurer l'intensité d'une seconde lumière réfléchie, qui est réfléchie par une surface de réflexion interne de la chambre de combustion, de la première lumière réfléchie qui est réfléchie par le miroir optique dichroïque ; et une unité de commande, connectée à l'oscillateur infrarouge et au capteur optique pour commander ces derniers, pour déterminer la quantité de matières solides flottantes contenues dans les flammes dans la chambre de combustion sur la base de l'intensité mesurée de la seconde lumière réfléchie.
(KO) 가스터빈 연소상태 진단장치가 개시된다. 본 발명에 따른 가스터빈 연소상태 진단장치는, 일단부에 개구부가 마련되어 가스터빈용 연소기 내측 공간과 연통되고, 타단부는 외측으로 돌출형성되어 이루어지는 연소진단튜브; 상기 연소진단튜브 일측과 연통되도록 구비되어 상기 연소진단튜브 내부로 적외선을 발생시키는 적외선발진기; 상기 연소진단튜브 내에 구비되어 상기 적외선 일부만 상기 연소기 내측으로 제1 반사시키고, 나머지는 투과시키는 이색광학거울; 상기 이색광학거울을 통해 반사된 제1 반사광 중 상기 연소기 내측 반사면에 의해 되돌아오는 제2 반사광의 세기를 측정하기 위해 상기 연소진단튜브의 타단부에 구비되는 광센서; 및 상기 적외선발진기 및 상기 광센서와 연결되어 제어하고, 측정된 상기 제2 반사광의 세기에 기초하여 상기 연소기 내의 화염에 포함되는 부유성 고형물의 많고 적음을 판별하는 제어부를 포함하는 것을 특징으로 한다.
