Abstract

본 발명은 연소기의 공연비 제어기술에 관한 것으로, 예열공기의 온도를 감지하는 감온소자(7)를 통해 감지되는 급기부의 온도를 기준온도와 비교하여 그들간에 차이가 날 경우 가스밸브(1)의 비례뱐을 조절하여 열검지소자(7)의 전류치가 최적과잉공기비(m=1.2)가 되도록 하므로써 강제 급,배기식 가스보일러의 최적연소조건을 실현할수 있다.The present invention relates to an air-fuel ratio control technology of the combustor, and compares the temperature of the air supply unit detected through the temperature sensing element (7) for detecting the temperature of the preheated air with the reference temperature when the difference between them of the gas valve (1) By adjusting the proportional power so that the current value of the heat detection element 7 becomes the optimum excess air ratio (m = 1.2), the optimum combustion condition of the forced gas supply / exhaust gas boiler can be realized.

Claims (1)

마이콤(8-3)의 버너(2)의 화염을 검출하는 감온소자(7)를 통해 예열공기의 온도를 감지하여 공연비(m)를 제하되, 예열공기의 온도가 설정온도의 범위에 있는 것으로 판단되면, 입력된 팬의 회전수와 가스밸브의 구동전압에 대응되게 모터(4) 및 가스밸브(1)를 구동시키고, 공연비(m)의 값이 작아지면, 분출 가스량을 기준 가스량의 레벨보다 1레벨 낮추고 그래도 화염이 불안정한 경우 분출 가스량을 1레벨을 더 낮추며, 과잉공기비가 커지면 가스량을 1레벨씩 올려 정상 연소가 이루어지게 제어하는 것을 특징으로 하는 연소기의 자동공연비 제어방법.Detecting the temperature of the preheated air through the temperature sensing element (7) for detecting the flame of the burner (2) of the microcomputer (8-3) to reduce the air-fuel ratio (m), the temperature of the preheated air is within the set temperature range If it is determined, the motor 4 and the gas valve 1 are driven in correspondence with the input rotational speed of the fan and the driving voltage of the gas valve, and when the value of the air-fuel ratio m becomes smaller, the amount of blown gas is higher than the level of the reference gas amount. If the flame is unstable even if the level is lowered by one level, the blowdown gas amount is further lowered by one level, and when the excess air ratio is increased, the gas amount is increased by one level to control normal combustion. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
