Abstract

On the basis of experimental and operational data, the basic parameters and Danilin criterion d of systems for the dry quenching of coke are established, and a method is developed for calculating their basic technological and operational characteristics, including the diameter of the quenching chamber, the dust content of the circulating gases beyond the quenching chamber, and the composition and characteristics of the dust-trapping and energy equipment. A classification is proposed for existing and prospective components of the dry-quenching system on the basis of the Danilin system. This system employs the Danilin diagram, which permits the development of dry-quenching systems with low dust content of the circulating gases beyond the quenching chamber. That opens a new level of design, permitting the creation of economical and reliable dry-quenching systems, without the need for a dust-collection bunker ahead of the waste-heat boilers (Danilin dry-quenching system of class C) and without the need for that bunker or dust-trapping cyclones ahead of the blast fan (Danilin dry-quenching system of class D). That improves the economics of dry quenching.
