METHOD OF OPERATING A BATTERY OF COKE OVENS WITH A REGENERATIVE CHANGE OF DRAUGHT

摘要

A method of operating a battery of coke ovens with a regenerative change of draught, heating walls which are divided into heating flue rows alternating with ovens in which adjustment of the combustion in the heating flues is used to ensure uniform heating of the oven contents vertically. Control elements, such as oven curtains dampers or the like, are used to control the operation of the discrete heating flues of each heating wall to ensure uniform heating of the oven contents lengthwise of the oven and of the discrete heating walls along the battery to ensure uniform heating of all the ovens. The gas quantity supplied per unit of time and adjusted for a carbonization time corresponds to a high battery throughput. The nature of the heating of the heating flues, and the position of the control elements are maintained for a relatively long carbonization time, and interruptions or pauses are introduced within each regenerative half-period as a means of dealing with reduced heat consumption.
