These plates are spacedone foot apart and are placed longitudinally with thetreater. The discharge electrodes are in turn placedbetween these plates and are also spaced one footapart, thus giving a series of discharge points to everyfoot square of the Section Through Treater. Some dust adheres to the discharge is shaken off each hour by means of a few lightblows with an insulated hammer on the suspensionframe. The gases enter the chamber without any previouscooling at a temperature of about 550 degrees C. Inpassing through the chamber the velocity is reducedto about ten feet per second and the gases lose aboutone-half of their heat, the exit gases having a tempera-ture of about 250 degrees C.
