Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion. RECENT INDUSTRY TRENDS
Fire protection systems for reducing the hazards of fires and explosions of coal pulverizers and bunkers and experience in operating these systems with a variety of pulverizing equipment using mainly Midwest coal are discussed. The fire protection systems used involve the
Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious.
Fire Detection Methods For Coal Pulverizer Systems-2-1the attrition mill is a high speed mill with little capability for retaining coal. therefore, fuel pockets cannot form and create a smoldering fire. if fire enters the mill from storage, detection could be made only by in- frared detectors at the inlet. because the product moves through the pulverizer in approximately 30.
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
