The emergence of biomass based energy warrants the evaluation of syngas from biomass gasification as a fuel for personal power systems. The objectives of this study were to determine the performance and exhaust emissions of a commercial 5.5 kW generator modified for operation with 100% syngas at different syngas flows and to compare the results with those obtained for gasoline operation at same electrical power. The maximum electrical power output for syngas operation was 1392 W and that for gasoline operation was 2451 W. However, the overall efficiency of the generator at maximum electrical power output for both the fuels were found to be the same. The concentrations of CO and NO(x) in the generator exhaust were lower for the syngas operation, respectively by 30-96% and 54-84% compared to the gasoline operation. However, the concentrations of CO(2) in the generator exhaust were significantly higher by 33-167% for the syngas operation.
生物质能源的出现使得将生物质气化产生的合成气评估为个人动力系统的燃料成为可能。本研究的目的是确定经过改装以 100%合成气运行的商用 5.5kW 发电机在不同合成气流下的性能和废气排放，并将结果与相同电功率下汽油运行的结果进行比较。合成气运行的最大功率输出为 1392W，而汽油运行的最大功率输出为 2451W。然而，发现两种燃料在最大功率输出时的发电机整体效率相同。与汽油运行相比，合成气运行时发电机废气中的 CO 和 NO(x)浓度分别降低了 30-96%和 54-84%。然而，合成气运行时发电机废气中的 CO(2)浓度却显著升高了 33-167%。
