摘要：A heat carrier gas is passed through a coke dry cooling plant in direct contactwith hot coke therein to form dry cooled coke while simultaneously increasing thetemperature of the heat carrier gas. The heat carrier gas is then passed through a coalpreheating plant to directly contact and dry and preheat moist coking coal containedtherein. The entire system is open, such that a given quantity of the heat carrier gaspasses only once through the dry cooling plant and the coal drying and preheating plant.The heat carrier gas may be a flue gas which is passed directly to the coke dry coolingplant without any preliminary pretreatment, and preferably is a flue gas which is supplieddirectly from a regenerator or recuperator of a coke oven battery. Alternatively, the heatcarrier gas may be in the form of a fuel gas which is inert with respect to the hot coke, forexample a waste gas or stack gas supplied from an adjacent metallurgical installation,such as a steel mill.
