Coal to Biomass Conversion

Coal Milling • 43t/hr processing –coal is ground to fine powder (75% thro' 75micron) • Coal CV ~24MJ/kg • Brittle material • Mill inlet temp ~ 260-300°C • Outlet temp target 90°C Biomass Milling • 50t/hr target throughput (giving similar heat input to coal) • Wood pellets are broken back to constituent particles

Advances in pulverised fuel technology: understanding coal ...

Extensive investigations were carried out in the mills and modifications were made to accommodate the low HGI coal. The OEM data for the 'E' mills does not give consideration to HGI values below 45, but estimated output at HGI 45 is 90% of mill rated capacity. This issue can be overcome by either increasing power or reducing particle fineness.
