Explosion supression systems are installations which detect a dust explosion at the very beginning and interrupt its propagation through the rapid dispersion of an extinguishing medium. The bild-up of an unacceptably high pressure is thereby prevented and the explosion limited to the inside of the protected vessels and apparatus. The prerequisite for this measure is a pressure-resistant design for the anticipated reduced explosion pressure.
