System for the safe handling of pulverized coal
A system for the safe handling of pulverized coal includes conventional coal pulverizing and drying equipment, with cyclones and bag filters added, the latter serving to separate the fine coal from the conveying gas (usually air); and explosion suppression and fire suppression systems, both of which include conventional components. All three of these systems are so combined as to effect the grinding of raw coal whereby to dry and collect the pulverized coal in an oxygen containing atmosphere without property loss due to explosion or fire. Fire detectors, explosion detectors, and associated extinguishers are also strategically located throughout the system. Preferably the fire suppression system will go into actuation prior to the explosion suppression system and when this happens, the explosion suppression system may be shut down manually if the operator decides it will not be needed, whereby to avoid the expense of having to reload the explosion suppression system.
