Method for the treatment of pit-wet, rough-crushed crude lignite for pneumatic conveyance into a fluidised-bed furnace

In this method, the production of a free-flowing lignite stream is to be directy integrated into the existing comminution and/or conveying process. This is achieved by feeding a gaseous heat carrier and quicklime to the crude lignite in a comminution and/or conveying process, pre-drying the crude li...

Summary:In this method, the production of a free-flowing lignite stream is to be directy integrated into the existing comminution and/or conveying process. This is achieved by feeding a gaseous heat carrier and quicklime to the crude lignite in a comminution and/or conveying process, pre-drying the crude lignite stepwise, further comminuting it stepwise, thermally and mechanically, and covering it with the quicklime stepwise.
