As a result of the growing trend to move production enterprises from cities to industrial parks, many newly constructed coke plants are in remote locations. That poses difficulties for the associated coke dry quenching (CDQ) systems: geographical dispersion of the systems; the challenges of maintenance and operation; and scarcity of qualified production and service personnel. In the present study, to address these concerns, a smart system for remote maintenance and operation of dry quenching systems is proposed, on the basis of the industrial internet. This system, based on three level cloud–interface–device architecture, integrates digital twins, analysis of data from numerous sources, and hybrid intellectual diagnostics. That permits the creation of a new model for remote servicing of dry quenching systems on the 1 + N principle and the development of an integrated approach to remote smart servicing and operation that covers the whole quenching cycle. This approach has been successfully introduced at several production enterprises and is performing well.
