ABSTRACT

The ovens in a slot-type byproduct coke oven battery are separated by the heating

walls. The heating walls consist of a series of vertical and separate chambers

called flues. A single heating wall can have from 24 to 34 flues. A mixture of pre-

heated air and a fuel gas is introduced into the bottom of these flues. The combus-

tion of this mixture inside the flue heats the wall from the inside, thereby heating

the ovens separated by the walls. Each flue on each wall is equipped with an

observation port or inspection hole on the battery top. Through these inspection

holes, the conditions inside the flue can be observed and/or measured, for example, flue temperature. A battery can have nearly any number of ovens,

from as few as 30 or 40, to as many as 70 or 80. There is always one more heating

wall in a battery than there are ovens in a battery.
