Abstract

A device for separating gases and solids, particularly coal dust, during the carbonization of coal, particularly predried and preheated fine coal in coke ovens arranged in a battery which includes a standpipe extending upwardly from the top of the battery having a bend extending from the top of the standpipe downwardly into a collecting main, comprises, a vertically extending standpipe which extends upwardly from the top of the battery and has a bend at the top thereof extending outwardly and downwardly from the top and which includes a longitudinally extending collecting main connected into the lower end of the bend with a solids discharge line overlying the bend and extending substantially parallel to the collecting main. The solids matter discharge line includes a connection extending downwardly into the bend. Means are provided for spraying a liquid into the bend over the collecting line and the solids matter discharge line includes a shutoff control in the connection to the bend. Exhauster means are connected to the solids matter discharge line for exhausting the gases enriched with the solids to a combustion furnace where they are burned. The combustion furnace may be one whi…
