Abstract (en)
[origin: EP0347519A2] To eliminate waste and residual products resulting from the recycling of waste paper in the paper and cardboard industry, the waste products are predehydrated. Storage problems are avoided virtually completely if the predehydrated waste materials are dried in a drier (6) to a residual water content of 25 % by weight in relation to the solid quantity and are subsequently stratified continuously on a vibrating grid (2), overlaid with the residual products and burnt with underblast, to form slag, in an associated combustion furnace (1) with a slag collector (8). The combustion gases are used especially in a convential steam generator (9) for steam generation. <IMAGE>
