A Hartmann Tube is used to investigate which explosions?

Explanation:
Assessing explosibility of combustible dust in air using a Hartmann Tube involves igniting a dust cloud in a small, confined tube to observe the resulting pressure rise and determine if an explosion can propagate. This setup is specifically used to screen and study dust explosions, giving insight into how easily a dust-air mixture can ignite and propagate a flame in confinement. It’s not about metal fires or BLEVE, which involve different mechanisms and test methods, and while dust explosions are a form of deflagration, the Hartmann Tube’s purpose is to characterize the explosibility of powders in air. Hence, the Hartmann Tube is used to investigate dust explosions.
