In the early 1980's there were indications that not only were p.c. mill fires and explosions a major cause of electric utility down time, but that foreign experience with p.c. mill study was established to survey foreign utility experience with pulverized coal (p.c.) fires and explosions and to relate this to U.S. experience. Sources of foreign p.c. technology were located and visits made to Japan, Australia, England, France, Germany and Switzerland to gather foreign knowledge and experience with p.c. fires and explosions. Pulverized coal mill manufacturers, operators, researchers and regulators were visited. Research on p.c. explosions is reviewed along with implications of the research into operating procedures. Recommendations are made to increase operator efforts to identify and fight undiscovered p.c. fires.
