For example, to grind a ton of coal to a d 50 around 500 µm, about 7–36 kWh of grinding energy is required, while that for raw poplar and pine, the energy requirement would be 130 and 170 kWh, respectively (Esteban and Carrasco, 2006). There is thus nearly an order of magnitude increase in energy consumption for biomass grinding.
Different energy sources are measured in different units: litres, therms, BTU, kWh, units, cubic metres and many more. This makes it very difficult to compare the actual costs for powering a heating system between different energy sources. For this reason, standardised units and costs are needed. We have done these calculations for the main fuel.
