Description
図4Aおよび図4Bは、従来型ランス(これは、テーパ付き部分34を省いている)からの燃料ガス流(この場合、プロパン)を示す流線図である。これら流線図は、入口構造体10を通る流量が毎分50標準リットルの窒素、毎分18標準リットルの酸素であり、ランス30を通る燃料ガスの流量が毎分3.2標準リットルであることを前提としている。具体的に説明すると、図4Aは、燃料ガス流量の流線を示しており、この場合、螺旋ばね50は、ノズル構造体12内でランスを越えて軸方向に延び、図4Bは、螺旋ばね50がランスを越えて軸方向に延びることがない場合の燃料ガス流量の流線を示している。理解できるように、燃料ガスは、全体としてノズル構造体12の中央の軸方向の領域内に留まり、かかる燃料ガスは、流出ガス流の外側シースによって同軸に包囲されている。燃料ガスのモル分率は、流出ガス流の希釈に起因して低下する。
