Abstract:
A plant for producing char and fuel gas includes a fluidized bed reactor having a first inlet in a lower region of the fluidized bed reactor configured to supply a primary fluidizing gas, a second inlet disposed above the first inlet and configured to supply a secondary gas, and a third inlet configured to supply dried and crushed coal. A further reactor is configured to perform a further process, the further reactor being directly connected to the fluidized bed reactor via a first conduit. A pneumatic injection and/or transportation system is disposed between the fluidized bed reactor and the further reactor. The first inlet is connected to a first supply of a first gas having an oxygen content which is smaller than a second supply of an oxygen enriched second gas connected to the second inlet.
