Abstract:
A mill (5) for milling a solid fuel, which comprises: feed rate-adjusting means (3a, 3b) for adjusting the feed rate of the solid fuel; a concentration-measuring means (7) for measuring the carbon monoxide and/or carbon dioxide concentration(s) at the outlet of the mill (5); and a memory means (11) for storing, as an analytical value, the ratio of the oxygen content and/or hydrogen content of the solid fuel to the carbon content thereof, wherein the feed rate-adjusting means (3a, 3b) are controlled by a controlling means (11), based on the result of the measurement by the concentration-measuring means (7) and the analytical value, so as to vary the ratio of the oxygen content and/or hydrogen content of the solid fuel fed to the mill (5) to the carbon content thereof, said ratio being in the same type as the analytical value. According to the aforesaid structure, ignition in the mill (5) can be prevented.
