- 燃焼室内に設けられたバーナと、給気口から燃焼用空気を取り入れて該バーナに供給するファンと、該ファンを所定時間回転させて燃焼室内の排気を行うプリパージを実行した後に該バーナに点火する燃焼制御手段とを備える燃焼装置において、
前記給気口と前記ファンとの間に設けられて、可燃性ガスの濃度を検出するガス検出手段を備え、
前記燃焼制御手段は、前記プリパージを開始する前に、前記ガス検出手段により予め設定された上限濃度以上の可燃性ガスが検出されるか否かを確認し、該上限濃度以上の可燃性ガスが検出された場合は、前記プリパージを禁止することを特徴とする燃焼装置。 - 燃焼室内に設けられたバーナと、給気口から燃焼用空気を取り入れて該バーナに供給するファンと、該ファンを所定時間回転させて燃焼室内の排気を行うプリパージを実行した後に該バーナに点火する燃焼制御手段とを備える燃焼装置において、
前記給気口と前記ファンとの間に設けられて、可燃性ガスの濃度を検出するガス検出手段を備え、
前記燃焼制御手段は、
前記プリパージの実行中に、前記ガス検出手段により予め設定された上限濃度以上の可燃性ガスが検出されるか否かを確認し、該上限濃度以上の可燃性ガスが検出された場合には、前記バーナへの点火を禁止し、
前記プリパージの実行中に、前記ガス検出手段により、前記上限濃度よりも低く設定された下限濃度より高く、前記上限濃度よりも低い範囲内の濃度の可燃性ガスが検出されるか否かを確認し、該範囲内の濃度の可燃性ガスが検出された場合には、前記所定時間を延長して前記プリパージを実行することを特徴とする燃焼装置。 - 前記範囲内の濃度の可燃性ガスが検出された場合に注意を促す注意手段を備えることを特徴とする請求項2に記載の燃焼装置。
