Abstract
【解決手段】内部で燃料が燃焼される燃焼容器10と、上記燃焼容器10内に燃料を噴射し火炎を形成するバーナ11とを備える燃焼器1であって、上記燃焼容器10に対して外側から接続されると共に、上記燃焼容器10内部に定在波を形成する音響波が入り込む音波管12を備える。
【選択図】図1
Description
燃焼容器10の内部の定在音響波は、長さがλ/2の奇数倍の管に入り込みやすい特性があると考えられる。音波管12に入り込んだ定在音響波は、音波管12内部のλ/2の奇数倍の距離を通過し、燃焼容器10内に戻される。このとき、音波管12に入り込んだ定在音響波は、燃焼容器10内の定在音響波と位相がずれた状態で燃焼容器10へと戻されることとなる。これにより、音波管12に入り込んだ定在音響波は、燃焼容器10内の定在波を弱め、燃焼容器10内の定在音響波を相殺し、振動を小さくすると考えられる。
