Abstract
With this rotating cylinder driven on the outer periphery and running on rollers with pipes or connections that are provided in the area of the rotating cylinder heads connected to the rotating cylinder ends for product intake, product gas removal, and solid matter discharge for thermal treatment, low-temperature carbonization or pyrolysis of liquid or solid substances or mixed phases by indirect heating, to improve the sealing function and increase the service life of the sealing packings there is provided between the driven and the stationary parts of the rotating cylinder on both the intake and the discharge side a floating slide ring sealing system. A nonpositive frame structure for each makes possible a revolving joint between the rotating cylinder and the two stationary rotating cylinder heads connected with the pipes or connections.
