In recent years, the possibility of producing coke continuously from poorly caking coal and blends in a moving bed under pressure, using both vertical and horizontal ovens, has been studied. The process is based on periodically adding charge to a charging chamber in specified batches, compacting it with a pusher and advancing it into the coke oven. As it progresses through the oven the charge undergoes all the stages of thermal processing to emerge as coke. Investigations on the interactions between the carbonizing charge and the oven walls have contributed greatly to information on the possible design of continuous bed carbonization equipment and the development of ways and means to attain higher efficiency and prolong the life of the oven brickwork. The continuous carbonization process is essentially a bed process analogous to that carried out in batch-type ovens. The oven in which the charge undergoes its thermochemical transformation is similar in construction to the batch-type coke oven. It follows that the designs for continuous oven should be based on accumulated experience in the design and operation of batch-type coke ovens. Continuous carbonization ovens of the requisite durability and strength can be developed by simultaneous improvements in two complementary directions.The pressures on the heating walls can be reduced primarily by optimizing the shape of the oven and the carbonizing cycle. These possibilities have been explored in experiments using tensometers in the walls of section I. The loads on the linings of continuous carbonization ovens are concentrated within a small section of the caking zone; they can be significantly lowered by increasing the oven taper (flare) and the strength of the charge bed.
