論文名稱: 甲醇/生質碳漿燃料及燃燒特性分析 / Analysis of methanol/bioslurry fuel and combustion characteristics
中文摘要:
本研究配製由焙燒椰子殼與甲醇組成的生質漿料燃料，並以實驗室規模旋流穩焰燃燒器，測試生質量最高15 wt%的混合物，與純甲醇比較著火特性、火焰穩定性、熱釋放率與NOx、CO排放。漿料展現迅速著火，火焰穩定性與純甲醇相當，旋流燃燒器即使在高生質含量下仍能穩定錨定火焰；能量轉換有效、熱輸出充足，僅峰值火焰溫度略降。NOx在中等生質比例時下降逾20%，15 wt%時幾乎測不到，主要歸因於火焰溫度降低與氮轉化路徑改變；CO則隨生質含量增加持續下降，顯示燃燒更完全。
英文摘要:
This thesis prepares a biomass slurry fuel of torrefied coconut shell and methanol and studies its combustion in a laboratory-scale swirl-stabilized burner with up to 15 wt% biomass, comparing it with pure methanol on ignition, flame stability, heat release, and NOx and CO emissions. The slurry ignites rapidly and keeps flame stability comparable to pure methanol, and the swirl burner anchors the flame even at high biomass loading. Energy conversion is efficient and heat output sufficient, with a slight drop in peak flame temperature. NOx falls by over 20% at moderate biomass ratios and is nearly undetectable at 15 wt%, mainly due to lower flame temperature and altered nitrogen conversion, while CO decreases continuously with biomass content, indicating more complete combustion.
