Method of controlling a coking cycle.

摘要

The endpoint of devolatilization of a coal mass in a coke oven during a coking cycle is determined by providing a probe which is capable of supplying an electrical signal which indicates the effective thickness of a layer of carbon deposited on the probe by gas released from the coal mass and in addition indicates the rate of devolatilization of the coal mass which is a measure of the heat input to the coal mass and can be used to control heat input to the coke oven.
