How to switch a power station off coal - Drax

Aug 22, 2018 · When converting a generating unit, the steam turbine and generator itself remain the same. The difference is all in the material being delivered, stored, crushed and blown into the boiler and burned to heat up water and create steam. And because biomass can be a volatile substance much more so than coal this process must be a careful one.
