    Pulverizer failure cause analysis. Final report

    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

    All coal pipes (and flows to all of the burners from each respective pulverizer) should be balanced and within +/- 2% of the mean flow. Perform a seal air check. Begin the normal pulverizer start sequence. Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty

    Solid fuel that spills over the bowl and into the area below the bowl can cause a fire since it is exposed to the hot drying air entering the coal mill. The coal mill scrapers will usually sweep the fuel pieces around to the debris chute and discharge them; however, a fire is likely to occur if a coal buildup occurs at the hot air inlet to the mill. Hot surfaces. Hot surfaces such as hot bearings, cutting, or welding can start a coal dust fire
