Sep 03, 2016 · 1 Introduction Pulpmills are among the largest users of woody biomass and typically store and process huge volumes of wood chips prior to the pulping process. Storage volumes of 120,000 BDt (750,000 m³) are not uncommon. The value of these chips is in the tens of millions of dollars, so mills have very specific requirements

For this reason, when raw biomass is fed through the coal feeder for pulverization in a mill designed for coal, the output of the mill reduces accordingly. If the plant has spare mill capacity, it can maintain the thermal input in the furnace but at the expense of additional energy consumption by the mills.
