DDWT coal-refinement Schwarze Pumpe
At the coal-refinement location Schwarze Pumpe VATTENFALL Europe Generation has etablished a pilot plant for dying raw lignite. The plant works as charged -steam fluidized-bed – drying (DDWT). The objective is the use of this technology in power-plant-units with CCS-technology, for which pre-dried lignite is used. The raw lignite which is already mechanically processed (chrushed and screened), is dying in a fluidized-bed driert, for the most part the deposition of the dry coal takes place through a bag filter.
The vapor is passed in a closed circuit and provides the inerting. The pilot plant at Schwarze Pumpe supplies the local CCS pilot plant with dry coal.
