The fill-level inside the mill can be controlled and kept constant with SMARTFILL coal. The result is a more constant particle size of the coal dust which ends up in a more steady flame and stabile combustion with less carbon in ash content. The ignition of the flames becomes more stable which is a direct effect of a continuous coal mass flow.
