Abstract

Calcination of petroleum coke in a rotary kiln is monitored by optical pyrometer inspection, inward from the coke discharge end, at a plurality of places spaced longitudinally inside the kiln, with the improved result of enabling the kiln to be controlled so that desired readings at one of the places, e.g., nearest the coke discharge end, are not impeded or falsified by flame and smoke conditions caused by burning of volatiles. Since pyrometer readings are found to produce a special signal due to flame or smoke, the use of the plural inspections permits detecting the location of such conditions and controlling the kiln to keep the flame and smoke from reaching the place of desired readings.
