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] .
