- バーナの燃焼排ガス中の顕熱を回収する主熱交換器と、主熱交換器を通過した燃焼排ガス中の潜熱を回収する副熱交換器と、副熱交換器の下流側の燃焼排ガス中のCO濃度を検出するCOセンサとを備えるCOセンサ付き燃焼装置であって、
COセンサは、COの検出部を内蔵する筒状のセンサ本体と、燃焼排ガスを検出部に導く多孔材料で形成したガス導入部とを備えるものにおいて、
検出部から軸方向に離れたセンサ本体の部分に、燃焼排ガスが流入するガス流入口が形成されると共に、センサ本体のガス流入口を除く部分が閉塞され、
センサ本体内に、センサ本体の内部空間を検出部を収納する内室とガス流入口に連通する外室とに区画するようにガス導入部が設けられ、
副熱交換器の下流側の排気通路に、ガス流入口が下方または斜め下方を向く姿勢でCOセンサが配置されることを特徴とするCOセンサ付き燃焼装置。 - 前記センサ本体の軸方向一端面に前記ガス流入口が形成され、前記副熱交換器の下流側の排気通路に、ガス流入口を下側にした鉛直姿勢または傾斜姿勢で前記COセンサが配置されることを特徴とする請求項1記載のCOセンサ付き燃焼装置。
- 前記センサ本体の軸方向一端寄りの周面部分の周方向一側部に前記ガス流入口が形成され、前記副熱交換器の下流側の排気通路に、ガス流入口を下方に向けた水平姿勢で前記COセンサが配置されることを特徴とする請求項1記載のCOセンサ付き燃焼装置。
