Description
Claims (2)
- 空気に燃料ガスを混合し、混合気をファンを介してバーナに供給する予混合装置であって、燃料ガスを供給する流量調節弁を介設したガス供給路の下流端がファンの上流側の空気供給路に接続され、空気供給路の通気抵抗を大小に切換える空気抵抗切換手段と、流量調節弁よりも下流側のガス供給路の部分の通気抵抗を大小に切換えるガス抵抗切換手段とを備えるものにおいて、
空気抵抗切換手段は、空気供給路内に回動自在に設けられたバタフライ弁で構成され、
バタフライ弁の下流側の空気供給路の部分に、バタフライ弁を配置した空気供給路の部分と同心で、且つ、この部分よりも断面積が小さなベンチュリ部が設けられ、
ガス抵抗切換手段の下流側のガス供給路の部分に、ベンチュリ部を全周に亘り囲うガス室と、ガス室からベンチュリ部の下流側に隣接する空気供給路の部分に燃料ガスを吸引するガス吸引部とが設けられ、ガス吸引部は、ベンチュリ部の下流側に隣接する空気供給路の部分の全周に亘り燃料ガスが吸引されるように形成されることを特徴とする予混合装置。 - 前記バタフライ弁の回転軸線に直交する断面形状はひし形であることを特徴とする請求項1記載の予混合装置。
