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

explosion. Explosions in coal mill systems are confined explosions, which means that the pressure effects must be dealt with by protective techniques to prevent the pressure rise from exceeding the strength of the plant, either by venting the expanded air into the atmosphere or by suppressing the combustion. Smaller sections of the plant, such as intermediate hoppers, can
Modernisation of the coal mill in terms of explosion safety was necessitated the hazards posed by the coal dust/air mixture at the time of contact with e.g. hot surface, mechanical and electrostatic sparks, open fire source as a source of ignition. The risk was related mainly to the equipment involved in storage, grinding and pneumatic transport processes. The task of our
PULVERIZED COAL EXPLOSIONS IN THE U.S. UTILITY INDUSTRY by RICHARD C. CARINI Manager, Engineering Administration and K.R.

Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant. Explosions have occurred when the flow drops and flames in the burning chamber pass back along the ductwork delivering fuel.

01/06/1993 In the early 1980s there were indications that not only were pulverized coal (p.c.) mill fires and explosions a major cause of electric utility down time, but that the incidence of foreign p.c. mill explosions was lower than in the US. This study was established to survey foreign utility experience with p.c. fires and explosions and to relate this to US experience.
