Abstract
【解決手段】淡火炎(F1)を生成する複数の淡炎孔(46)と、前記淡炎孔(46)の周囲に配置されて濃火炎(F2)を生成する複数の濃炎孔(48−1、48−2)とを備えることにより、前記濃炎孔(48−1、48−2)で生成される前記濃火炎(F2)が連結されて前記淡火炎(46)を囲い込むことにより、前記濃火炎(F2)で前記淡火炎(F1)を保炎する。

Description
→ CO2 +2H2 O+2* 79/21* N2 ・・・(1)
→ CO2 +2H2 O+λ(2* 79/21* N2 )+(λ−1)* 2O2
・・・(2)
式(1) は、メタンを理論空気量で燃焼させた場合の反応式、式(2) は、空気比(λ)を考慮した場合の反応式である。メタンの高位発熱量を39.8〔MJ/m3〕とすれば、メタンのガス流量は、
58.1〔kW〕/39.8〔MJ/m3〕
=5.26〔m3 /h〕 ・・・(3)
であり、理論空気量(λ=1)は、式(1) より、
2+2* 79/21=9.52〔m3 /m3 〕 ・・・(4)
となる。そこで、58.1〔kW〕時の理論空気量は、
5.26〔m3 /h〕* 9.52〔m3 /m3 )=50.3〔m3 /h〕
・・・(5)
となる。
となる。58.1〔kW〕時のλ=1.3の空気量は、
5.26〔m3 /h〕* 12.4〔m3 /m3 〕=65.4〔m3 /h〕
・・・(7)
となる。式(5) および式(7) からも明らかなように、空気比を増やせば、燃焼空気量はその比に比例して増加する。その結果、炎孔部38におけるガスおよび空気の混合気の流出速度も同様に増加するが、燃焼速度とのバランスにより火炎の安定度が決定される。
