Abstract (en)

[origin: EP0271642A2] The device, for burning in particular unreactive coal dust, has an axial feed for the coal dust and a swirling device for the combustion air on the front end of a combustion and acceleration chamber, on the inner wall of which the coal dust/air mixture undergoes a helical motion, and also has an ash-discharge opening in the wall of the combustion and acceleration chamber. The invention is characterised in that the wall of the combustion and acceleration chamber (11) has axially or substantially axially directed narrow longitudinal slits (20) following successively in the circumferential direction of the chamber. <IMAGE>
