Abstract

본발명은 가스보일러 주변 및 실내에서 산소결핍으로 인한 인명피해를 방지하는 가스보일러의 안전 연소방법에 관한 것으로, 가스보일러의 동작이 시작되면 시스템을 총제어해 주는 회로제어부(마이콤)는 개스밸브(1)를 열어 버너(4)를 점화시키는 점화단계와, 점화가 되면 열검지봉(3)이 일정시간(T)동안 변동되는 불꽃 (7)의 세기를 전압값으로 변화하는 불꽃전압 변환단계와, 상기 변화된 전압의 기준값을 마이콤이 설정하는 기준전압설정단계와 상기 변동되는 불꽃전압변화를 다수회 검지하여 평균내고 퍼센티지(%)로 만드는 변동전압 평균단계와, 상기 평균전압값이 기준설정 전압값 이상이면 보일러 동작을 정지시키고 이하이면 정상동작을 시키도록 하는 평균값 기준값 비교단계와를 구비한 것이다.The present invention relates to a method of safe combustion of a gas boiler to prevent human injury due to lack of oxygen in and around the gas boiler, and a circuit control unit (microcom) for total control of the system when the operation of the gas boiler starts is a gas valve ( 1) the ignition step of opening the ignition of the burner (4), and the spark voltage conversion step of changing the intensity of the flame (7) in which the heat detection rod (3) fluctuates for a predetermined time (T) to a voltage value when ignition occurs A reference voltage setting step of setting a reference value of the changed voltage by a microcomputer, a variable voltage average step of detecting and averaging the varying flame voltage change to a percentage and the average voltage value being a reference setting voltage value If it is above, the boiler operation is stopped, and if it is below, it is provided with the average value reference value comparison step.

Claims

When the gas boiler starts operation, the circuit control unit (microcom) which controls the system totally opens an ignition step of igniting the burner 4 by opening the gas valve 1, and when the ignition is performed, the heat detection rod 3 is operated for a predetermined time ( A flame voltage change step of converting the intensity of the flame 7 which is varied during T) into a voltage value, a reference voltage setting step of setting a reference value of the converted voltage by Micom, and detecting the fluctuation of the flame voltage multiple times The average value of the variable voltage to make an average and a percentage (%), and the average value reference value comparison step to stop the boiler operation if the average voltage value is higher than the reference set voltage value and to operate normally if the average voltage value is less than the reference voltage. Safe combustion method of a gas boiler, characterized in that to prevent the lack of oxygen.
