| 摘 要： | 利用农林废弃物可控热裂解产生的生物质气,经除尘、除焦油及冷却处理后作为火花点火生物质气发动机的燃料,对发动机的性能进行试验研究.通过测试发动机的转速波动、燃气消耗率和有害排放物,分析发动机的动力性、经济性、运转稳定性和排放性.试验数据表明:发动机怠速运转稳定;较大的功率范围内具有较低且平坦的气耗率曲线;全负荷范围内的转速波动率满足并网发电的需要;发动机的HC、CO和NOx的排放水平较低;燃烧过程中无焦油沉积现象.因此,农林废弃物可控热裂解产生的生物质气,可以作为火花点火发动机的代用燃料.

| Abstract: | The performances of spark-ignition biogas engine were studied by using the biogas as the fuel, which was produced from the controllable thermal cracking of agricultural and forestry residues with the procedures of removing dust and tar as well as cooling. The speed fluctuation, biogas consumption rate and harmful exhaust of the spark-ignition biogas engine were tested, and the output power, economic performance, running stability and exhaust characteristics were analyzed. The experimental data showed that the engine could run stably at the idle speed, the biogas consumption rate was low and flat in a large range of power, the speed fluctuation within the full load could meet the demands of national electric network, the exhaust amounts of HC, CO and NOx were low, and no tar deposition arose in the process of combustion. So the conclusion was drawn that the biogas produced from the controllable thermal cracking of the agricultural and forestry residues could be used as the alternative fuel of the spark-ignition engine. |
