ABSTRACT:
A flue-stream reactor for gasifying fossil fuels which contain ballast. The reactor comprises two cylindrical, cooled, and insulated reaction chambers which are disposed one after the other in the axial direction. The first reaction chamber is provided with an axial inlet for accommodating a gasification burner. The second reaction chamber is provided with an opening for the addition of gasification material. A cooled, coaxial channel provides communication between the two reaction chambers. The reactor further includes a radial discharge and a device for removing liquid and solid ash and slag. As viewed in the axial direction of flow, the first reaction chamber includes a cooled deflection hood ahead of the inlet of the connecting channel, thereafter a cooled, annular, trough-like device which is intended for collecting liquid ash and slag, is disposed on the wall of the chamber, and is provided with a discharge, and thereunder a water bath which is disposed between the connecting channel and the wall of the chamber; the second reaction chamber is provided ahead of the outlet with a cooled deflection hood which is furthermore disposed above the funnel-shaped discharge for the solid ash and slag.
