  • CASE HISTORY RETROFIT OF COAL MILL EXHAUST FAN

    RETROFIT OF COAL MILL EXHAUST FANSTUDY OF FAN PERFORMANCE AND EROSION David R. Grupp Director of Research Robinson Industries Inc. 400 Robinson Drive Zelienople PA 16063 Abstract Coal pulverizer mills are utilized in many coal fired power generation facilities across the country and around the world. Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill which therefore needs to be explosion pressure and shock-resistant. NFPA requires coal mills to be good for 50 PSI.

    Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill which therefore needs to be explosion pressure and shock-resistant. NFPA requires coal mills to be good for 50 PSI. The current study is a continuation of the work reported by Wingerden et al. (2011). Dust explosion experiments were performed in a roller mill (capacity 36 metric tonnes coal/hour internal

  • Fire and Explosion Prevention in Coal Pulverizing Systems

    The potential for fires and explosions inherent in air and pulverized coal mixtures has been studied for over 60 years. Design and operating practices have evolved to a state that allows the safe practicable utilization of air-conveyed coal pulverizing systems for direct firing steam generators.
