method for uniform heating of coke ovens (a horizontal chamber and installation for the practice of

摘要

The coke oven battery has heating walls with pairs of heating flues separated from each other by a wall with an upper opening therein to permit combustion gases flowing upwardly in one flue to flow through the opening and downwardly through the adjacent flue. An opening is also provided in the separating wall adjacent the bottom of the flues to permit recirculation of a portion of the downwardly flowing waste gas. Each of the flues have inlet openings adjacent the base of the flues for combustion gas and air. There are also provided jet nozzles adjacent the base of each flue and jet nozzles adjacent the top portion of each flue to supply through one or more of the nozzles streams of high velocity propellant gas into the preselected flues in the same direction as the flow of gases therein. The streams of high velocity gas control and intensify the recirculation of gases within the adjacent flues to thus provide a more uniform vertical distribution of temperature in the flues and the adjacent coke charge.
