System for the safe handling of pulverized coal

Abstract. 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.

EP0132974A2 Safety systems for coal pulverizers

A safety control system for a coal pulverizer utilizes signals (20,22) representing net oxygen and carbon monoxide measurements of the pulverizer atmosphere. A signal (50) representing the rate of carbon monoxide change is derived form the signal (22) by a derivative controller (48). The signals (20,50) representing the net oxygen measurement and rate of carbon monoxide change are compared in
