Abstract

Abstract

Experiments were conducted to investigate the effect of conveying airflow characteristics on flame structure for the electric spark ignition in air flow of lycopodium dust.Hot wire anemometers were used to measure the distributions of velocity and turbulent intensity along the diameter in a 6 cm diameter and 4 m length horizontal acrylic tube of a blow-type pneumatic conveying system.The measured dust-air mixtures flowing velocities ranged between 10 and 30 m/s.A high-speed video camera was utilized to record the flame propagation process and to obtain the direct light emission photographs.Two apparently different types of flames appeared in the flame propagation process under different airflow conditions.Type A flame was characterized by a regular and continuous structure with the yellow light-emitting zone in the center surrounding by the red luminous zone.Type B flame was discrete in the space and the structure of the luminous zone was irregular.Furthermore, the flame propagation velocities, vortex structures, formation conditions and relative burning velocities of the two types flames under different airflow velocities were discussed in detail.
