Description Flame emissivity is an important parameter in the study of pool fires. A series of pool fire experiments are carried out with four different fuels namely diesel, gasoline, hexane and kerosene for pool diameters of 0.10 m, 0.13 m and 0.20 m. Flame emissivity at a height of 0.25 times the pool diameter from the base is measured by observing the flame with reference to a black body using infrared camera. Influence of pool diameter (0.3 m, 0.34 m, 0.5 m, 0.7 m and 1.0 m) on flame emissivity at a height of 0.25 times the pool diameter is studied with diesel as the fuel. Variation of flame emissivity with the height of the flame along the center of diesel pool fire is investigated for diameters of 0.3 m, 0.5 m, 0.7 m and 1.0 m. It is observed that the flame emissivity is less at the tip of the flame in comparison with that at the base of the pool fire. The measurement of flame emissivity by observing flame with reference to a black body using infrared camera is corroborated with the measurements conducted with reference to an electrically heated black body for diesel pool fires with diameters 0.3 m, 0.5 m and 0.7 m. Flame emissivity is also inferred from the mass burning rate measurements for diesel oil pool fires of 0.3 m, 0.5 m, 0.7 m and 1.0 m diameters. Flame emissivities are independent of the measurement method. Temperature and surface emissive power distributions of the diesel pool fires for diameters 0.3 m, 0.5 m, 0.7 m and 1.0 m are computed using infrared thermography.
