As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the twostage pulverizing sec tion.
Coal. There is no coal mining or coal tar in Finland, and all coal is imported. According to Finnwatch () there are 13 coal power plants in Finland. The companies Pohjolan Voima, Fortum, Helsingin Energia and Rautaruukki are the largest coal consumers. According to the Finnwatch inquiry in 2010 none of the Finnish companies had yet a commitment to coal phase out.

This calls for completely different mill types or significant modifications to the existing mills and classifiers. BioC has experience from conversion of coal mills for biomass operation as well as coal burners. A modern Low NOx coal burner is not well suited for pulverised biomass but can often be converted with moderate changes.
