Description
Claims (1)
- 燃焼室に配置した複数のバーナと、バーナに燃焼用空気を供給する燃焼ファンとを備え、燃料ガスを供給するバーナの組み合わせを変更して、バーナ全体の燃焼能力を最低段たる第1段の燃焼能力と中間段たる第2段の燃焼能力と最高段たる第3段の燃焼能力とに切換えるようにした燃焼装置であって、バーナ点火後の燃焼初期段階に第3段の燃焼能力で燃焼量が所定の共鳴音発生領域に入っているときに共鳴音が発生するものにおいて、
共鳴音発生領域の下限燃焼量より低く、バーナ点火時の燃焼量である点火燃焼量より高い所定の燃焼量であって、第2段の燃焼能力の上限燃焼量以下で第3段の燃焼能力の下限燃焼量以上の範囲に含まれる燃焼量を起点燃焼量として記憶しておき、バーナ点火後、要求燃焼量が起点燃焼量以上であるか否かを判別して、要求燃焼量が起点燃焼量以上であって、且つ、第2段の燃焼能力の上限燃焼量以下である場合は、バーナ点火後所定時間経過するまで第2段の燃焼能力で燃焼量を起点燃焼量に維持し、その後、第2段の燃焼能力で燃焼量を要求燃焼量まで増加し、要求燃焼量が第2段の燃焼能力の上限燃焼量を上回る場合は、バーナ点火後所定時間経過するまで第3段の燃焼能力で燃焼量を起点燃焼量に維持し、その後、第3段の燃焼能力で燃焼量を要求燃焼量まで増加することを特徴とする燃焼装置。
