The vapor pressure of a mixture of liquids is the weighted average, by mole fraction, of the vapor pressures of the contributing liquids. (the vapor pressure is the tendency of a liquid to turn in to a gas- the boiling point of a liquid is defined as the point when the vapor pressure of a liquid equals atmospheric pressure) Hence one would want to mix the most volatile, flammable liquid you can that is miscible with the biodiesel. If I were doing it I would start my mixing small amounts of white gas or gasoline with the biodiesel until I got the minimum proportion which supported combustion under the desired conditions. Isopropyl alcohol would work, but I think it has a higher vapor pressure and lower heat of combustion than gasoline so it would take a higher proportion to achieve the same effect. > -Mike > > Zeke Yewdall wrote: > >> What about the type of burners that are designed to use a liquid fuel >> directly rather than volatilize a liquid fuel?
