These beater wheel mills are used to pulverise the crude lignite needed to generate steam. Hot flue gas is sucked into the beater wheel mill to dry the coal. While the coal is being pulverised, the coal dust is mixed with the flue gas, resulting in a high drying efficiency. The lignite/flue gas mixture is blown to the pulverised coal burner

stable flames. In conventional lignite-fired units, this is generally achieved through simultaneous milling and drying in beater wheel mills in which hot furnace gas of ~1000°C drawn from the upper part of the boiler furnace is circulated. In this method, the energy used for drying lignite is the high grade heat in the

In conventional lignite stations, the fuel is dried using hot flue gases, which are sucked from the steam generator furnace at a tem-perature of 900 to 1,000°C and conducted to the beater wheel mills: there, they withdraw much of the lignite's moisture from the lignite while it is being pulverized. If this combined process is decou-

In mills of this type, as commonly practiced, the conveying gas and material mixture is conducted from the mill into ya reverse flow separator, cyclone classifier or sifting screen, in which the oversized or coarseparticles are separated from the mixture and are returned to the mill for further grinding -by being passed again through the beater wheel.

Beater wheel mills in lignite power stations usually have a flue gas recirculation duct which allows the use of hot flue gas to dry the lignite during the grinding process. The beater wheel itself is grinding element as well as mill fan at the same time.
