A dust explosion apparatus suitable for use in lecture demonstrations

摘要

Classroom demonstrations enhance the sensing learning style that many engineering students use.This simple apparatus,which can be constructed with components found at a local discount store for under us20,effectively demonstrates the nature of dust explosions.The demonstration can be used to complement a lecture in thermodynamics (combustion,heating,and rapid expansion of gases),process design (hazards involved with solids handling),or process safety (dust explosions and vent sizing).
