Abstract
Description
一次空気数(化学量論的量)は、僅かなダスト放出を達成させるために、1.0未満、特に0.7〜0.9に調節される。
この試験例の試験は、最適な燃焼パラメーターの測定に使用された。
第1の試験例と同様に、試験装置TAMARA中で燃焼を行なった。燃料の供給量を固体の燃焼含分が一定であるように調節し、それによって排ガス焼却帯域からの流出後に排ガス中の一定の酸素含分は、乾式で11〜11.5体積%を生じた。
ハウスダスト(Hausmuell)は、前記の試験装置TAMARA中で燃焼される。
前記の試験例の範囲内で、試験装置TAMARA中で約0.65の一次空気数および乾式で一定の約10体積%の排ガス(ボイラーの後方)中の酸素含量でハウスダスト燃焼(Hu=7MJ/kg)を行なった。個々の火格子領域内での火格子速度は、前記の試験例とは異なり同一でなく;この火格子速度は、燃焼床領域P1およびP2(前方の火格子の半分)内で22cm/分で一定であり、それぞれ燃焼床領域を有する後方の火格子の半分内でさらに減少する(P3:11cm/分、P:5cm/分)。その結果、前記の燃焼床領域P1〜P4内での固体燃料の相対滞留時間の分布は、12対12対24対52%であった。前記の運転パラメーターによって、前記の一般の関係に基づいて既に、排ガス焼却帯域の後方で測定された約150mg/Nm3の低い窒素酸化物形成値および良好に焼却されたスラグが達成された。
