Fire and Explosion Prevention in Coal Pulverizing Systems
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will
Fire and Explosion Prevention in Coal Pulverizing Systems
Fires are generally caused by accumulations of powdered coal brought to temperatures above their ignition temperature, either by hot air flowing over the deposit or by the deposit laying out on a hot surface. In addition, active fires are sometimes fed into the system from the bunker. TIME - INITIAL VOLUME OF REACTANTS IGNITION '.13 -
