Abstract
A method for the thermal treatment of dispersible raw material may inovlve introducing raw material into a riser tube that is perfused by hot gases and thermally treating the raw material with the hot gases. Furthermore, the method may inovle feeding a fuel to the riser tube. The fuel may initially dwell in a fuel-conditioning region on a bearing face, where the fuel comes into contact with a part of the hot gas that is mixed with the raw material. Consequently, the fuel is dried and/or at least partially de-gassed and/or at least partially reacted and subsequently transferred into the riser tube.

A method for thermal treatment of dispersible raw material, the method comprising:
- introducing raw material into a riser tube that is perfused by hot gases;
- thermally treating the raw material in the riser tube with the hot gases;
- feeding a fuel into a fuel-conditioning region and onto a bearing face disposed in a conditioning chamber that leads into the riser tube, wherein at least 50% of the hot gases that come into contact with the fuel is formed by a part of the hot gases that is mixed with the raw material and deflected into the conditioning chamber, whereby as a result the fuel is at least one of
- dried,
- partially or completely de-gassed, or
- partially or completely reacted;
- and
- transferring the fuel into the riser tube.
A system for thermal treatment of dispersible raw material, the system comprising:
- a riser tube that is perfusable by hot gases;
- means for introducing raw material into the riser tube;
- and
- a fuel-conditioning region that comprises means for adding fuel, a bearing face for the fuel, and means for conveying the fuel along the bearing face and transferring the fuel into the riser tube, wherein the fuel-conditioning region is connected to the riser tube such that a part of the hot gases that is mixed with the raw material reaches the fuel-conditioning region and comes into contact with the fuel, whereby the fuel is at least one of
- dried,
- partially or completely de-gassed, or
- partially or completely reacted.
