<p>The solids-heating rotary kiln is very suitable for waste (A) pyrolysis. Within (13) the drum (8), parallel tubes (12) are heated by an internal flow of hot gases (h). At the colder end of the tubes, in the last-thirds of their length, turbulators (4), i.e. turbulence inducing rings, are located on the inner tube surfaces. The rings are pref. of stainless steel, rectangular or round in cross section, and offset from each other by given distance; fastened to a pair of locating wires (42) running through, either inside or outside the rings.</p> |
