TEMPERATURE CONTROL OF DELIVERED COKE.

In analyzing known methods for determining the heat engineering conditions of coke batteries the authors concluded that an installation with a photoelectric pyrometer should be adopted. However, to avoid various drawbacks, the readings of the pyrometers must be continuously connected for dust and smoke emissions. Techniques for accomplishing this are presented. The authors obtain a formula to calculate the tube temperature of the coke when radiation pyrometers are used. It is emphasized that installations similar to the authors' that permit continuous measurement of coke temperature from the working chambers throughout the mass of coke cake are absolutely essential for control of the heating of the coke batteries.
