A Hartmann Tube is used to investigate which type of explosion?

• A. Dust explosions
• B. Deflagration
• C. Metal fire
• D. BLEVE

Answer: (A)

The Hartmann tube is a small, simple test setup used to judge whether a dust dispersed in air can propagate a flame and cause an explosion in a confined space. By igniting a dust–air mixture in a vertical tube and observing flame propagation, you assess the explosibility of the dust cloud. This is specifically about dust explosions, not metal fires or BLEVE scenarios. While dust explosions involve rapid flame spread (a form of deflagration) in a confined dust cloud, the key idea the device tests is the potential for a dust explosion in industrially relevant conditions.
