Abstract

The invention provides an abrasion device (300) for continuously removing coke from the inner wall of a cylindrical part (114) of a rotating reactor (110), wherein the abrasion device comprises a base frame (310) with suspensions (311) for mounting auger scrapers (320), wherein said suspensions (311) are mounted at the base frame (310) and connect an upper part (312) and a lower part (313) of the base frame (310); said lower part (313) of the base frame (310) comprises at least one auger scraper (320), wherein said at least one auger scraper (320) comprises a central roller (321) with an outer auger helix (322), said at least one auger scraper (320) being rotatably mounted at cross members (314) at the lower part (313) of the base frame (310) at the ends of the suspensions (311), wherein the lower part (313) comprises weights (330); and wherein the abrasion device is configured to generate a contact pressure >70 N/mm2 to the inner wall of a rotating reactor (110). The invention provides a reactor comprising the abrasion device. The invention further provides a system (100) for continuous processing of heavy fuel oil from recycling waste oil and the processing residues of crude oil into useful products comprising means for feeding waste oil; at least one hot-gas filter, at least one condenser, at least one rotating kiln comprising an outer stationary jacket (120) which forms a heating channel (121), and an inner rotating reactor (110), and the abrasion device (300) for removing solid coke from the rotating reactor (110). The invention further relates to a process for continuous processing of heavy fuel oil from recycling waste oil and the processing residues of crude oil into useful products, preferably with the system of the invention.
