Study of the structure of vapor-gas flows in the arch space of a ring oven with direct heating

The production of special types of coke for electrochemical processes, ore agglomeration, production of phosphorus and other fields of industry is an important economic problem. The use of ring coking ovens for this purpose permits use of poorly-caking and gas coal, unsuitable or suited, in a limited manner, for coking in chamber ovens, in the metallurgical and chemical industries, producing reducing agents and fuel with the assigned group of properties according to the user specifications, and eliminating the use of scarce metallurgical coke in non-blast furnace processes with a simultaneous improvement in efficiency. It is also promising to use ring ovens as equipment for thermal processing of plastic coal molds within the framework of the molded coke technology. The advantages of using ring ovens are discussed.
