Reports of 26 coal pulverizer fires and explosions are reviewed in order to elucidate causes and preventive measures. Most of the explosions occurred during pulverizer shutdowns or restarts. The most common ignition scenario involved coal dust accumulations in the mill spontaneously igniting and coming in contact with a flammable coal dustair suspension during a mill shutdown or restart.

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
