Burning behavior of a fuel droplet in a quiescent high‐pressure atmosphere has been studied experimentally to explore the effects of the ambient pressure just around the critical pressure of fuel. Since the natural convection changes the transport field around the burning droplet, microgravity field made by a falling apparatus were used to suppress the natural convection generated by the droplet burning. Experiments showed that spherical flames were obtained for ambient pressures both below and above the critical pressure of fuel. As the ambient pressure is increased, the burning life time decreases and reaches the minimum at the critical pressure of fuel, beyond which the burning life time increase. Flame diameter increases during the burning time to a maximum and then decreases to burnout. This behavior is the same both below and above the critical pressure of the fuel. The maximum flame diameter attained during burning is a function of pressure and decreases with ambient pressure throughout the range investigated. There is no change in slope or minimum at the critical pressure.
