In this paper, some preliminary measurements and observations were conducted to investigate the interaction of water mist with pool fires. The fire source is a small-scale circular stainless steel pan with heptane, ethanol and kerosene as fuel. Water mist was generated by a downward-directed pressure nozzle that was positioned on a square steel plate 300 mm over the fuel sample and was operated at pressures of 0.5 MPa. The water mist characteristics were determined by a LDV/APV system. The radiation spectra of the flames were measured by a monochromator and the radiant heat flux was obtained by a thermogage before and after application of water mist. Thermography was used to visualize the thermal field of the flame. The experimental results show that the interaction mechanisms of kerosene flame are different from those of ethanol and heptane.
