    Coal Pulverizers - an overview | ScienceDirect Topics

    The main boiler was built as coal-fired, which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire. Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for 100% wood pellets [76]

    APPLICATION PROFILE - Fire Protection Technologies

    The potential for explosions in pulverized coal processes is well known. Equipment such as crushers, pulverizers, and conveyors all contribute to the creation of dust. When this coal dust is suspended in air (in the pulverizer, conveying lines, bag filters, cyclones, and storage bins) and an ignition occurs, there is the potential for explosion
