A Study on the Mixed Fuel Characterization

혼합연료의 특성에 관한 연구

  • Published : 1990.09.01


Two pure fuel oils(#1 oil, #6 oil), theree pure alcohols (methanol, ethanol, propanol) were tested for the fuel characteristics such as miscibility (that established which pure fuels and fuel mixtures could be fired in the boiler), flash point, viscosity. Specific target of the study besides the oil/alcohols or oil/alcohol mixture without any modification and with safety. #1 oil could be mixed without any problems at all concentrations with two of the alcohols; these were the ethanol and propanol. However, miscibility of #6 oil with any alcohols and #1 oil with methanol was not possible and very limited in this study. The measurements of flash point and viscosity for the mixtures were done for the comparisons with the pure fuels. There was a marked change of flame shape and flame luminosity as the alcohol content of the mixtures was increased. The mixture flame shortened and became non-luminous compared with a pure fuel oil flame.
