Abstract

본 발명은 강제급배기식 보일러의 배기 연도의 이상을 감지하기 위한 방법에 관한 것으로서, 더욱 구체적으로는 보일러의버너에서 연소된 배기 가스를 배기팬을 사용하여 강제적으로 배기하는 통로인 배기 연통이 배기 가스에 의한 부식등에 의하여 막히는 경우에 이것을 감지하기 위한 보일러의 배기연통 막힘 감지방법에 관한 것이다.The present invention relates to a method for detecting an abnormality of the exhaust flue of a forced exhaust type boiler, more specifically, the exhaust communication which is a passage for forcibly exhausting the exhaust gas combusted in the burner of the boiler using an exhaust fan is exhausted The present invention relates to a method for detecting a blockage of exhaust communication of a boiler for detecting this when blocked by corrosion by gas.

본 발명의 보일러의 배기연통 막힘 감지방법은, 보일러 작동시 배기 연통에 설치된 배기팬의 회전수를 측정하고 이것을정상 상태시의 회전수와 비교하여 보일러 배기 연통의 이상 유무를 판단하는 것을 특징으로 한다.The exhaust gas clogging detection method of the boiler of the present invention is characterized by measuring the rotational speed of the exhaust fan installed in the exhaust communication during boiler operation and comparing this with the rotational speed in the normal state to determine the abnormality of the boiler exhaust communication. .
