Description
1はU字状の加熱ヒータ2を埋設した有底筒状のアルミダイキャスト製の気化器で、改質器(図示せず)が内蔵された筒体3の上部に下向きに取り付けられているものであり、この気化器1の側壁内で、加熱ヒータ2近傍の上部一側内には燃料噴霧用のノズル4と、燃焼用の一次空気供給路5とが上部に連通した小容積の気化室6を有し、この気化室6で前記一次空気と燃料噴霧用のノズル4からの液体燃料の噴霧とを受けて気化ガスを含む予混合気を生成し、気化室6からの予混合気の気化及び混合を促進する大容積の気化混合室7を気化室6の横に備え、この気化室6と気化混合室7を噴出部8で連通している。
本燃料電池システムの起動時では、加熱ヒータ2に通電し、気化器1が加熱されて液体燃料の気化に適する所定の温度に達したことを温度センサ27が検知すると、ノズル4からの液体燃料及び一次空気供給路5から供給される一次空気が共に気化室6内に噴霧される。

Claims (1)
- 改質器に改質反応用の熱を供給する燃料改質用バーナにおいて、前記バーナは加熱ヒータを備え液体燃料を気化し一次空気と予混合する予混合方式で、前記一次空気と燃料噴霧用のノズルからの液体燃料の噴霧とを受けて気化ガスを含む予混合気を生成する気化室と、前記気化室からの予混合気の気化及び混合を促進する気化混合室と、前記気化室と前記気化混合室とを連通し前記気化室で生成された予混合気を前記気化混合室の内側壁に向けて噴出させる噴出部を設け、前記噴出部は気化室底部をV字状として内方側に気化室側壁を形成し、この気化室側壁と一次空気及びノズルを備えた接続継ぎ手の先端部とで形成した事を特徴とする燃料改質用バーナ。
