Abstract
Description
Claims (2)
- 보일러 내부의 튜브누설로 인해 발생하는 파를 음향감지수단에서 감지하여 증폭기에서 증폭하여 제어유니트에 입력하여 분석함에 의해 보일러 내부의 튜브 누설위치 및 누설량을 감지하는 보일러 튜브감지장치에 있어서,상기 음향감지수단(21)은 보일러의 벽튜브에 용착된 전달봉(41)과, 상기 전달봉(41)의 단부에 결합된 음향센서(43)를 포함하고 있고, 보일러의 벽 다수위치에 결합되어, 보일러 내부의 튜브누설로 발생하는 고주파 및 저주파 대역의 신호를 동시에 감지할 수 있게 된 것을 특징으로 하는 보일러 튜브누설 감지장치.
- 제1항에 있어서,상기 음향감지수단(21)과 증폭기사이에는 이 음향감지수단에서 감지된 신호가 노이즈의 영향을 받지 않도록 이 신호를 반파정류하는 전치증폭기(Preamplier)(23)가 연결되어 있는 것을 특징으로 하는 보일러 튜브누설 감지장치.
