Method and apparatus for determining the covering of a coke wharf with quenched coke

摘要

A wharf for receiving glowing coke, comprises an inclined receiving ramp which has a plurality of non-conducting areas and conductive plates interposed in the conductive areas at spaced locations. An electrical circuit control means is connected to each of the plates and provides a potential on the plates which will vary in accordance with the presence of coke over the plates. The electrical circuit also includes a control for effecting a control pulse in accordance with the potential sensed for carrying out a subsequent operation, such as the positioning or withdrawal of a rake element at the bottom of the wharf which supports the coke. With the method, by subjecting the conductive plates to an electrical potential, and by sensing the change in the potential, it is possible to regulate the amount of covering of the coke on the wharf.
