A comparative experimental study was conducted for fluff-type solid refuse fuel which was known to be difficult to apply thermal process, using two lab-scale gasifiers; downdraft fixed bed and bubbling fluidized bed reactors, to find out the best available option for gasification of this type of fuel. The experiments were carried out at 900 °C, by changing the air equivalent ratios ranged from 0.2 to 0.6, and analyzing the syngas composition, yield, and contents of C₂–C₆ related with tar content. The results showed that the gasification performance in terms of syngas yield, heating value of syngas, cold gas efficiency, carbon conversion efficiency, and tar content was generally better in the bubbling fluidized bed reactor than the downdraft fixed bed reactor. The best results were obtained at 0.4 of air equivalent ratio in a bubbling fluidized reactor, with producing the highest quality of syngas, having syngas composition with 72.53% of H₂ + CO and 0.483% of C₂–C₆, and showing 14.43 MJ/Nm³ of lower heating value. At this condition, 0.74 m³/kg of gas yield rate, 67.31% of cold gas efficiency, and 63.70% of carbon conversion efficiency were obtained. With the results from this study, the gasification process with bubbling fluidized bed reactor could be suggested that it was more suitable for better efficient application to solid refuse fuel with more stable operation.

使用两个实验室规模的气化炉，对难以进行热处理的绒毛状固体垃圾燃料进行了对比实验研究；向下气流固定床和鼓泡流化床反应器，以寻找最佳的可燃气化此类燃料的选择。实验在900°C下进行，通过将空气当量比从0.2更改为0.6，并分析合成气的组成，收率和C ₂ -C _6的含量与焦油含量有关。结果表明，在鼓泡流化床反应器中，就合成气产率，合成气的热值，冷气效率，碳转化效率和焦油含量而言，气化性能通常优于下流固定床反应器。在鼓泡流化反应器中以空气当量比为0.4可获得最佳结果，产生的合成气质量最高，合成气的组成为72.53％H ₂  + CO和0.483％C ₂ -C ₆，显示14.43 MJ / Nm ³较低的发热量。在此条件下0.74 m ³气体产率/ kg，冷气效率为67.31％，碳转化效率为63.70％。根据这项研究的结果，可以认为鼓泡流化床反应器的气化过程更适合于更有效地应用于固体垃圾燃料，并且运行更稳定。
