A series of experiments were conducted on quartz sand beds wetted with transformer oil under initial temperatures 80–140 °C and fuel–sand mass ratios 1:4–1:8. The flame spreading process over the fine bed limited liquid fuel can be divided into development quasi-steady stages. Experimental results reveal that spread rate in stage increases temperature ratio. effect width depends temperature. is insensitive to at low temperatures; however, it an close flash point fuel. This discrepancy mainly from enhanced capillary due decreased viscosity high temperatures. dominant factor determining vaporization and, thus, rate, radiation plays increasing role maximum height sensitive ratio but changes little dimensionless model was proposed predict normalized height.
