Abstract

본 발명은 연소되는 불꽃의 상태로부터 연소 상태를 파악하기 위한 방법에 관한 것으로, 불완전 연소되는 불꽃으로부터 방사되는 적외선을 감지하여 이상 연소 및 역풍의 유입을 감지하기 위한 적외선 센서를 이용한 역풍감지방법에 관한 것이다.The present invention relates to a method for determining the combustion state from the state of the flame to be burned, and relates to a reverse wind detection method using an infrared sensor for detecting the influx of abnormal combustion and the reverse wind by detecting the infrared radiation emitted from the incomplete combustion of the flame will be.

본 발명의 적외선 센서를 이용한 역풍감지방법은, 연소되는 불꽃에 인접하게 적외선 센서를 설치하고, 불꽃의 연소 상태를 따라서 발생되는 신호를 증폭하여 주제어부에 입력시켜 이상 연소나 역풍을 감지하는 것을 특징으로 한다.The reverse wind detection method using the infrared sensor of the present invention is characterized by providing an infrared sensor adjacent to the flame to be burned, amplifying the signal generated according to the combustion state of the flame to be input to the main control unit to detect abnormal combustion or backwind. It is done.
