Pool fire burning characteristics of biodiesel

The characteristics of pool fire burning of methyl esters/biodiesels of palm, soybean, coconut and their blends with diesel were compared against baseline diesel. Pool fires were established and investigated using four different crucible sizes, ranging between 40 mm and 70 mm in diameter to obtain t...
