Abstract: A system for calcination of oil green coke has a rotating furnace and a rotating cooler, the furnace being serviced by boiler, a combustion chamber and a chimney. There is a feeding system defined by a first mat carrying the green coke into a silo and another mat transporter to feed the furnace. At the end of the silo there are two discharge breadths for the oil green coke, where each breadth has two drawer-like feeders for feeding the green coke onto the mat transporter and, from this to the inside of the rotating furnace through a fall set.

Abstract: A sealing device for a rotating furnace and cooler for calcination of oil coke has lead plates mounted in sliding form on individual supports attached to a flange which constitutes the fixed part of the furnace or cooler. The plates are aligned side by side, forming a collar of coplanar plates encircling the external diameter of the furnace or cooler, forming a self-adjustable sealing curtain between the joint point of its rotating and fixed parts, while the cylindrical body presents a track against which all plates are handled and held with a certain pressure, maintaining the sealing between the rotating and fixed part of the set, both in the furnace and in the cooler.
