Abstract
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.
Claims5
A method of determining the devolatilization endpoint during a coking cycle comprising:
- (a) providing a probe adapted to measure the effective thickness of a layer of carbon deposited by gas released from coal during a coking cycle,
- (b) positioning said probe such that it is exposed to said gas, and
- (c) determining endpoint of devolatilization by providing means electrically connected to said probe to indicate effective thickness of carbon having a maximum value.
