Hallo Mark, I think biodiesel can be used easily in wick type stoves and lamps.
SVO on the other hand cannot be used with wicks, because its viscosity is too high, it does not get transported by the capillary forces, like kerosene. I tried to explain this facts in a small drawing, which you can visit at: http://jatropha.org/lamps/princ-burning.htm Since SVO is not vaporizing like kerosene, and is not replaced by new material by capillary forces in the wick, the wick itself burns and has to be replaced quite often. The SVO molekules are cracked by the heat of the flame, and a carbon deposit is formed. After some hours the flame fades, because the supply of SVO via the carbon layer is diminishing.
