| Abstract: | Experimental studies were conducted to investigate the behaviors of non-spread diffusion flames of different liquid fuels soaked in porous beds with different materials. Sand, steel bead and zeolite of the mean size of 2 mm were chosen as the porous beds with depth of 80 mm. The effects of the properties of the fuel on combustion behaviors, including flame phenomena, flame temperature profiles, vapor region moving speed and fuel consumption in the porous beds with different materials, were studied in the experiments. The results show the special combustion characteristics for the liquid fuel soaked in porous beds. |
