METHOD AND APPARATUS FOR COKING COAL BLENDS HIGH PERFORMANCE WITH SWELLING PRESSURE IN COKE OVENS 'NO RECOVERY' OR 'HEAT RECOVERY'

摘要

The invention relates to a method for coking coals having high driving pressure properties in a "non-recovery" or "heal-recovery" coking oven, wherein a coking oven buttery which is composed of coking oven chambers arranged side by side is used for cyclic coking of coal, and wherein an amount of coal preheated to a high temperature is admitted into the coking chamber that is to be filled at such a level that the driving pressure resulting from the coking can escape over the coke cake into the gas chamber, in such a manner that the coking oxen chamber wall surrounding the coking oven chamber is relieved by the driving pressure resulting from the coking. The invention also relates to a device with which this method can be carried out.
