일반적으로 발전소에 설치되는 가스터빈 연소기에는 이 연소실 화염상태의 이상 유무를 확인하는 화염 검출장치가 설치되어 있는바, 이 화염 검출장치는 가스터빈 연소기에 부착되어 가스터빈 운전중 연소기의 화염상태를 검출하도록 되어 있 다.In general, the gas turbine combustor installed in the power plant is equipped with a flame detection device for checking the abnormality of the flame state of the combustion chamber, which is attached to the gas turbine combustor to detect the flame state of the combustor during operation of the gas turbine. It is supposed to.

즉, 도 2에 도시한 바와 같이 가스터빈 연소기(100)에서 화염이 발생하면, 화염상태를 화염 검출기(102)로 검출하여 주제어실의 감시 모니터(107)에서 화염상태의 이상유무를 감시하도록 되어 있는데, 종래 가스터빈용 화염 검출장치는 연소기에 부착된 화염 검출기의 신호를 인가받는 감시 모니터에서 로직신호를 디스플레이하여 확인하도록 되어 있었다.That is, when the flame occurs in the gas turbine combustor 100, as shown in Figure 2, the flame state is detected by the flame detector 102 to monitor the presence or absence of the abnormal state of the flame in the monitoring monitor 107 of the main control room However, the conventional flame detection device for a gas turbine was to confirm by displaying a logic signal on the monitoring monitor that receives the signal of the flame detector attached to the combustor.

그러나 종래 장치는 실제로 연소실의 화염상태가 있을 때만 화염 검출기의 동작 이상 유무의 상태를 확인할 수 있으며, 동작이 불량할 때에는 화염 검출기 자체의 문제인지, 아니면 연소기의 화염상태가 불량한지 확인이 불가능하여 설비 유지 정비에 곤란함이 있었다.However, the conventional apparatus can check the status of the operation of the flame detector only when the combustion chamber is actually in a flame state, and when the operation is poor, it is impossible to check whether the flame detector itself is a problem or whether the flame state of the combustor is poor. There was a difficulty in maintenance.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 화염 검출기의 동작시험을 통하여 건전성 확인으로 정비 비용의 감소와, 신속한 장비의 고장 유무 판단과 조치로 설비 유지비 절감 및, 안정적인 전력공급에도 이바지하는 개선된 가스터빈용 화염 검출장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above conventional problems, the maintenance cost is reduced through the operation test of the flame detector, the maintenance cost is reduced, and the equipment maintenance cost is reduced and the stable power supply by determining whether or not the equipment failure quickly It is also an object of the present invention to provide an improved flame detection apparatus for gas turbines.

상기와 같은 목적을 달성하기 위한 본 발명은 가스터빈의 연소기에서 발생하는 화염을 화염 검출기로 검출하여 감시 모니터에서 감시하는 가스터빈용 화염 검출장치에 있어서, 상기 연소기에는 자외선 발생기를 갖춘 화염 검출기가 설치되고, 이 화염 검출기는 F/V 컨버터와 V/F 컨버터 및 펄스카운터에 직렬 연결되어 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention provides a flame detection device for a gas turbine for detecting the flame generated by the combustion of the gas turbine with a flame detector, the monitoring monitor, the flame detector is provided with an ultraviolet generator in the combustor The flame detector has a structure connected in series with an F / V converter, a V / F converter and a pulse counter.

이하, 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 전체 구성회로를 블럭화하여 나타낸 도면이다.1 is a block diagram showing the entire configuration circuit of the present invention.

본 발명은 가스터빈의 연소기에 부착되어 발생하는 화염의 이상유무를 검출하는 화염 검출기가 주제어실의 감시 모니터에 연결되어 이루어진 가스터빈용 화염 검출장치에 있어서, 상기 연소기에는 자외선 발생기(1)를 갖춘 화염 검출기(2)가 설치되고 이 화염 검출기(2)는 F/V 컨버터(3)와 V/F 컨버터(4) 및 펄스카운터(5)에 직렬 연결되어 이루어져 있다.The present invention relates to a flame detection device for a gas turbine in which a flame detector for detecting an abnormality of a flame generated by being attached to a combustor of a gas turbine is connected to a monitoring monitor in a main control room, wherein the combustor includes an ultraviolet generator (1). The flame detector 2 is provided and the flame detector 2 is connected in series with the F / V converter 3, the V / F converter 4 and the pulse counter 5.

여기서 상기 자외선 발생기(1)는 연소기의 화염에서 발생되는 것과 같은 자외선을 방출하게 되는데, 이때 자외선 발생기(1)에서 발생되는 자외선 신호가 화염 검출기(2)를 동작시키도록 되어 있다.
여기서 상기 자외선 발생기(1)는 연소실의 화염에 대응하여 자외선 파장(1900Å ~ 2600Å)을 조절하여 방출하게 되는데, 방출된 이 자외선 파장에 의하여 화염 검출기(2)가 작동된다.In this case, the ultraviolet generator 1 emits ultraviolet rays such as those generated in the flame of the combustor, wherein the ultraviolet signal generated by the ultraviolet generator 1 operates the flame detector 2.
In this case, the ultraviolet ray generator 1 emits by controlling the ultraviolet wavelength (1900 Å ~ 2600 Å) in response to the flame in the combustion chamber, and the flame detector 2 is operated by the emitted ultraviolet wavelength.

그리고 상기 화염 검출기(2)는 자외선 발생기(1)에서 나오는 자외선의 파장에 따라 인가되는 전기적 신호를 검출하여 전극에서 흐르는 전류를 공지의 전류 증폭회로를 통하여 증폭시켜 0 ∼ 1㎑의 범위 내의 주파수 신호를 발생하고, 이 주파수 신호를 F/V 컨버터로 인가시킨다.The flame detector 2 detects an electrical signal applied according to the wavelength of the ultraviolet light emitted from the ultraviolet ray generator 1 and amplifies the current flowing through the electrode through a known current amplification circuit to generate a frequency signal within a range of 0 to 1 GHz. Is generated, and this frequency signal is applied to the F / V converter.

상기 F/V 컨버터(3)는 주파수 신호를 전압신호로 변환시켜주는 변환기로서, 4㎃ ∼ 20㎃(6)를 이용하여 공지의 DC 터미널에서 기록계에 접속하여 트렌드를 분석하도록 되어 있다.The F / V converter 3 is a converter for converting a frequency signal into a voltage signal. The F / V converter 3 is connected to a recorder at a known DC terminal and analyzes a trend by using 4 kHz to 20 kHz (6).

또한 상기 V/F 컨버터(4)는 전압을 주파수 신호로 변환시켜주는 변환기로서, 가스터빈 주제어 시스템에서 주파수 신호를 받기 때문에 실제신호와 같도록 변환시 켜주는 역할을 하게 되어 있다.In addition, the V / F converter 4 is a converter for converting a voltage into a frequency signal. Since the V / F converter 4 receives a frequency signal from a gas turbine main control system, the V / F converter 4 converts the voltage to a frequency signal.

한편, 상기 펄스카운터(5)는 자외선 발생기(1)에서 발생되는 자외선 파장에 따라 이 자외선 파장에 대응 출력되는 전기적 신호와 화염 검출기(2)에서 검출후 출력되는 전기적 신호가 일치되는지 확인하는 지시계로서 주파수 0 ∼ 1㎑ 범위 내에서 지시되어 진다.On the other hand, the pulse counter 5 is an indicator for checking whether the electrical signal output corresponding to the ultraviolet wavelength and the electrical signal output after the detection by the flame detector 2 match according to the ultraviolet wavelength generated by the ultraviolet generator 1. The frequency is indicated within the range of 0 to 1 kHz.
