Effect of ignition delay time on selected explosion parameters of nicotinic acid in a mixture with air

摘要

Four nicotinic acid powder dusts were tested for explosion pressure and for max. rate of explosion pressure increase in air in a 20 L vessel to det. the effect of ignition delay time on the explosion characteristics. The increase in ignition delay time (55-70 ms) resulted in small increasing the explosion pressure and increasing the substantial explosion pressure rise.
