Abstract

Herein, the explosion characteristics such as the peak explosion pressure, maximum pressure rise rate and deflagration index of 2-methylfuran (MF)/air mixture have been investigated at high pressures and temperatures. Knowledge of these parameters can be used in the safety assessment of MF explosions. The explosion experiments were performed at the initial pressure of 1, 2, 3, and 4 bar, the initial temperature of 333, 363, 393, and 423 K and the equivalence ratio of 0.7–1.4 using a constant volume combustion bomb. The pressure data obtained from the experiment were carefully processed to examine MF peak explosion pressure, maximum pressure rise rate, explosion time as well as the deflagration index. Explosion characteristics of MF were sensitive to the initial pressure and temperature conditions and the mixture concentration. An increment in the initial pressure triggered a dramatic growth in the peak explosion pressure, maximum rate of pressure rise and the deflagration index. Alternatively, an increment in the initial temperature decreased the peak explosion pressure, maximum pressure rise rate and the deflagration index. By and large, MF explosion parameters obtained in this investigation can offer firsthand information on MF explosion hazard assessment at high pressures and temperatures.
