본 발명은 람다센서와 산소센서를 이용한 연료전지용 개질기 버너 제어방법에 관한 것으로, 특히 연료전지용 개질기 버너로부터 발생되는 배기 가스중의 산소 농도를 측정하여 연소효율과 버너의 연소 상태를 근거로 연료와 공기의 공급량을 피드백 제어하도록 한 람다센서와 산소센서를 이용한 연료전지용 개질기 버너 제어방법에 관한 것이다. The present invention relates to a method for controlling a reformer burner for a fuel cell using a lambda sensor and an oxygen sensor. In particular, fuel and air are measured based on combustion efficiency and combustion state of the burner by measuring oxygen concentration in exhaust gas generated from the reformer burner for a fuel cell. A method of controlling a reformer burner for a fuel cell using a lambda sensor and an oxygen sensor for controlling feedback of an amount of gas supplied.

연료전지 시스템은 스택(stack)의 연료극과 공기극 사이에서 수소와 산소가 전기화학 반응하여 전기와 함께 물과 열이 생성되는 시스템으로서 그 종류에 따라 연료로부터 수소를 얻어내기 위한 개질기(reformer)를 갖추기도 한다.A fuel cell system is a system in which hydrogen and oxygen are electrochemically reacted between a fuel electrode and an air electrode of a stack to generate water and heat together with electricity. The fuel cell system includes a reformer for obtaining hydrogen from fuel according to its type. Also do.

기존의 개질기(reformer)는 열원부와 개질반응부 및 일산화탄소저감부로 이루어지는데, 종래에는 주로 통형타입(tubular type)의 것이 사용되다가 최근에는 평판형타입(plate type)의 것이 사용되고 있다.Conventional reformers are composed of a heat source portion, a reforming reaction portion, and a carbon monoxide reduction portion. Conventionally, a tubular type is used, and recently, a plate type is used.

즉, 상기 평판형 개질기는 열원, 개질반응기 및 일산화탄소저감기가 모두 평판형으로 이루어져 적층(stacking) 구성되는데, 열원으로서 촉매연소기가 사용되 고, 일산화탄소저감기는 고온쉬프트컨버터(High Temperature Shift Converter) 및 저온쉬프트컨버터(Low Temperature Shift Converter)로 구성된다.That is, the planar reformer consists of a heat source, a reforming reactor, and a carbon monoxide reducer all composed of a flat plate, and is configured as a stacking source. A catalytic combustor is used as the heat source, and the carbon monoxide reducer is a high temperature shift converter and a low temperature. It consists of a Low Temperature Shift Converter.

따라서, 촉매연소기에서 발생되는 열을 이용하여 개질반응기에서 수소부유가스(Hydorgen rich gas ; 이하, 수소가스라 칭함)를 생성하고 일산화탄소저감기에서 그 수소가스에 포함된 일산화탄소의 농도를 적절히 낮추어 스택의 연료극으로 공급하게 되며, 공기극에 공기가 공급되어 상호 반응함으로써 물, 열의 생성과 동시에 전기가 생산되게 된다.Therefore, the reformed reactor generates hydrogen rich gas (Hydrogen rich gas) by using the heat generated from the catalytic combustor, and in the carbon monoxide reducer, the concentration of carbon monoxide contained in the hydrogen gas is appropriately reduced. The anode is supplied to the anode, and the air is supplied to the cathode to react with each other, thereby generating electricity and water at the same time.

또 기존에는 NG량과 공기의 량으로 결정되는 공기연료 당량비를 조절하여 배기가스의 완전 연소를 유도하고 있으나, 연료전지용 개질기 내의 연소 효율과 버너의 연소 상태에 따라 실제 람다(λ)값은 달라지게 된다. In addition, in the past, the combustion of exhaust gas is induced by adjusting the air fuel equivalent ratio, which is determined by the amount of NG and the amount of air, but the actual lambda (λ) value is different depending on the combustion efficiency of the fuel cell reformer and the burner combustion state. do.

따라서, 실제로 연료전지용 개질기 버너로부터 발생되는 배기가스 내의 유해가스를 저감시키기 위해 배기 가스내의 산소 농도를 계측할 필요가 있다.Therefore, it is necessary to measure the oxygen concentration in the exhaust gas in order to reduce the harmful gas in the exhaust gas actually generated from the reformer burner for fuel cell.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 람다센서와 산소센서를 이용한 연료전지용 개질기 버너 제어방법은, 도 1을 참조하여 설명하면, 연료전지용 개질기(10)의 배기가스가 배출되는 배기구 측에 배치되어 배기가스 중의 산소 농도를 측정하고 측정된 값을 전기적 신호로 출력하는 측정단계와, 출력된 전기적 신호를 인가받아 기 설정된 산소 농도치와 비교하여 정상 유무를 판단하고 이상 발생시 공기 연료 당량비를 제어하는 제어신호를 출력하는 제어단계를 포함한다.The reformer burner control method for a fuel cell using a lambda sensor and an oxygen sensor according to the present invention will be described with reference to FIG. 1, which is arranged on the exhaust port side through which exhaust gas of the reformer 10 for fuel cells is discharged. A measurement step of measuring and outputting the measured value as an electrical signal, and a control step of outputting a control signal for controlling the air fuel equivalence ratio in the event of an abnormality by determining the normality by receiving the output electrical signal and comparing it with a preset oxygen concentration value. Include.

더 상세히 설명하면, 측정단계는 연료전지용 개질기 버너(15)에 의해 연소되어 배기구(18)를 통해 배출되는 배기가스 중의 산소 농도를 람다 센서(25)와 산소센서(22)를 이용하여 복수회 측정한다.In more detail, the measuring step measures the oxygen concentration in the exhaust gas which is burned by the reformer burner 15 for fuel cell and discharged through the exhaust port 18 by using the lambda sensor 25 and the oxygen sensor 22 a plurality of times. do.

이때 람다 센서(25)와 산소센서(22)는 개질기(10)의 배기구(18) 측에 서로 이격되게 배치되어 배기가스 중의 산소 농도를 측정하는 동일한 기능을 수행하지만, 여기서는 촉매식 센서의 경우 수소와의 반응으로 인해 발생되는 오작동에 대한 안전장치로서 산소 농도를 복수회 측정하기 위해 구비된다.In this case, the lambda sensor 25 and the oxygen sensor 22 are spaced apart from each other on the side of the exhaust port 18 of the reformer 10 to perform the same function of measuring the oxygen concentration in the exhaust gas, but in the case of the catalytic sensor, hydrogen It is provided to measure the oxygen concentration multiple times as a safety device against malfunction caused by the reaction with.

또 람다 센서(25)와 산소센서(22)는 앞의 이유로 인해 서로 다른 방식의 것을 채용하는 것이 바람직하며, 일 예로 지르코니아형, 티타니아형을 채용할 수 있으며, 이 경우에는 람다 센서(25)가 지르코니아형일 때 산소센서(22)는 티타니아형을 채용하는 것이 바람직하다. 이와 반대일 경우일 수도 있다.In addition, it is preferable that the lambda sensor 25 and the oxygen sensor 22 adopt a different method for the above reasons, and for example, a zirconia type or a titania type can be employed, in which case the lambda sensor 25 is When the zirconia type is used, the oxygen sensor 22 preferably adopts a titania type. This may be the case.

즉, 람다 센서(25)와 산소센서(22)는 동일한 개념의 센서이지만, 여기서는 다른 방식의 것을 채용함으로써, 발생되는 수소와의 반응으로 인해 오작동되는 것을 방지할 수 있다.That is, although the lambda sensor 25 and the oxygen sensor 22 are sensors of the same concept, by employing a different type of here, it is possible to prevent malfunction due to reaction with hydrogen generated.

람다 센서(25)와 산소센서(22)는 배기가스내의 산소량에 따라 기전력이 가변되게 발생하고, 즉 기전력의 발생량은 외부 대기와 배기구(18) 내부의 산소 농도차에 따라 비례하는 상관 관계를 갖는다.The lambda sensor 25 and the oxygen sensor 22 generate a variable electromotive force according to the amount of oxygen in the exhaust gas, that is, the generated amount of electromotive force has a proportional correlation in accordance with the oxygen concentration difference between the outside atmosphere and the exhaust port 18. .

또한, 본 발명의 측정단계에서는, 배기가스의 유량 및 온도를 측정하는 단계를 더 구비하는 것이 바람직하다.In addition, in the measuring step of the present invention, it is preferable to further include the step of measuring the flow rate and temperature of the exhaust gas.

배기가스의 유량은 배기구(18)에 배치된 압력센서(40)를 이용하여 배출되는 배기가스의 압력을 계측하고, 이에 따라 배기가스의 유량을 측정할 수 있다.The flow rate of the exhaust gas can measure the pressure of the exhaust gas discharged using the pressure sensor 40 disposed in the exhaust port 18, and thus the flow rate of the exhaust gas can be measured.

또한, 배기가스의 온도는 배기구(18)측에 배치된 온도센서(30)를 매개로 측정할 수 있으며, 이는 배기가스의 유량을 보정하는 데 사용된다.In addition, the temperature of the exhaust gas can be measured through the temperature sensor 30 disposed on the exhaust port 18 side, which is used to correct the flow rate of the exhaust gas.

제어단계에서는, 산소센서(22)와 람다센서에 측정된 배기가스 중의 산소 농도를 전기적 신호로 변환하여 제어부(100) 측으로 출력하면, 출력된 전기적 신호를 근거로 미리 설정된 기준치 값과 비교하여 기준치보다 높은 값이 검출될 때 이상(異常)상태로 판단한다.In the control step, when the oxygen concentration in the exhaust gas measured by the oxygen sensor 22 and the lambda sensor is converted into an electrical signal and output to the control unit 100, compared with the reference value set in advance based on the output electrical signal than the reference value When a high value is detected, an abnormal state is determined.

이어서, 제어부(100)는 이상으로 판단될 경우 천연 가스와 공기의 공급량을 조절하여 완전 연소에 요구되는 공기 연료 당량비를 피드백 제어한다.Subsequently, if it is determined that the controller 100 is abnormal, the controller 100 controls the supply amount of natural gas and air to feedback-control the air fuel equivalent ratio required for complete combustion.

피드백 제어하는 과정은 개질기 버너(15)측으로 천연가스를 공급하는 NG 블로워(50)와 공기를 공급하는 에어 블로워(60)의 동작을 각각 제어하기 위한 제어신호를 출력하고, 이에 따라 연소에 적합한 공기 연료 당량비를 갖도록 제어한다.The feedback control process outputs control signals for respectively controlling the operations of the NG blower 50 for supplying natural gas and the air blower 60 for supplying air to the reformer burner 15, and thus the air suitable for combustion. Control to have a fuel equivalent ratio.

제어부(100)는 배기가스의 산소 농도를 람다 센서(25)와 산소센서(22)의 측정값을 개별적으로 판단하는 것이 바람직하며, 이때 둘중 하나의 측정값이 기준값보다 높을 경우 둘 중 하나의 오작동을 디스플레이부(70)를 매개로 외부로 디스플레이하기 위한 제어 신호를 출력함으로써, 작업자가 센서의 고장 유무를 확인한 후에 센서 교체작업을 수행할 수 있다.The controller 100 may determine the measured values of the lambda sensor 25 and the oxygen sensor 22 separately for the oxygen concentration of the exhaust gas, and in this case, one of the two malfunctions if the measured value is higher than the reference value. By outputting a control signal for displaying to the outside via the display unit 70, the operator can perform the sensor replacement work after confirming the failure of the sensor.
