Lying device for combustion of sulphur-containing, reactively inert coal dust

摘要

The invention relates to a lying device for combustion of reactively inert coal dust with an acceleration and combustion chamber, in the longitudinal axis of which the flame and a coal dust jacket surrounding it are set in swirling motion, which extend into the downstream boiler, characterised in that the acceleration and combustion chamber (11) is connected, via an opening in the rear chamber end wall (18) which is smaller in the cross-section of the acceleration and combustion chamber, to a second chamber (30), the cross-section of the second chamber is greater than the cross-section of the connection openings to the acceleration and combustion chamber (11) and to the boiler (49), and there are arranged in the second chamber pipelines which spray dust quantities which neutralise sulphur compounds into or onto the rotating flame and the coal dust jacket surrounding it. <IMAGE>
