  1. Combustion and Emission Characteristics of Engine Fueled with DDCL (Diesel of Direct Coal Liquefaction) 煤直接液化柴油的燃烧及排放性能 04 DEC 2009 Morgantown WV USA

  2. 内 容/Content • Brief introduction of Shenhua demonstration factory with capacity of 1.0Mt/a • Condition of the engine test • Combustion • Regulated emissions • Unregulated emissions • 神华100万吨/年示范装置简介 • 发动机台架试验情况 • 燃烧性能结果 • 常规排放结果 • 非常规排放结果

  3. 神华100万吨/年装置Shenhua demonstration factory • 2008年建成并试运行 • 稳定运行300多小时,生产了合格的石脑油、柴油等产品 • 正常停工改造 • Finished Construction in 2008 • Trial operation over 300hrs • Qualified naphtha, diesel • Normal shutdown and transformation

  4. 试验柴油性质Properties of test Diesel *DDCL-1 added cetane number additive known as DDCL-2

  5. 发动机参数Parameters of test engines measured in load characteristic mode, full load characteristic mode and ESC 13-mode.

  7. 欧II发动机Euro II engine 发动机扭矩Engine torque

  8. 欧II发动机Euro II engine 燃油消耗率比较Fuel consumption

  9. 欧III发动机Euro III engine 燃油消耗率比较Fuel consumption

  10. 欧II发动机Euro II engine NOx排放比较NOx Emission

  11. 欧II发动机Euro II engine 低碳烃排放Hydrocarbon emission

  12. 欧II发动机Euro II engine CO排放CO emission

  13. 欧II发动机Euro II engine 烟度排放Smoke emission

  14. 欧II发动机Euro II engine 十三工况常规排放对比Emissions in ESC 13-mode

  15. 欧III发动机Euro III engine CO、NOx排放比较CO and NOx emissions

  16. 欧III发动机Euro III engine 碳氢和颗粒排放比较Hydrocarbon and PM emissions

  17. 欧II发动机Euro II engine SO2排放对比SO2 Emission

  18. 欧II发动机Euro II engine 多环芳烃排放对比PAHs emissions

  19. 欧II发动机Euro II engine 烃类物质排放比较 Hydrocarbon emissions

  20. 总结Conclusions • 直接液化柴油硫、氮含量低，芳烃含量低，是优质的柴油组分。DDCL is good component of Clean Diesel due to almost no S、N, and lower aromatics • 采用DDCL能够提高发动机的动力性，功率提高2.4%～4.1%(欧II)。Engine power increase while fueled with DDCL. • 在欧II发动机上，常规排放有所改善，PM明显降低，CO排放降低。PM and CO emissions is lower while Euro II engine fuelled with DDCL. • 在欧III发动机上， NOx和PM排放与基准油相当，但CO和碳氢物质排放增加。 In Euro III engine: NOx and PM emissions almost not changed while CO and HC • 适当提高DDCL十六烷值，有利于改善排放.To increase the cetane number of DDCL appropriately is benefit to the reduction of the pollutants
