Control system and method for removal of coke from a coke oven

In a control system for providing incremental position regulation between the movement of a coke transfer car along a track in relation to the coke discharge side of a given coke oven chamber and the movement of a coke pusher advancing through that coke oven chamber from the opposite side thereof the push the coke into said car for providing a substantially uniform layer of coke in said car, said control system comprising:

• first means for generating first signal pulses at a predetermined pulse rate in accordance with the desired position of said ram,
• second means responsive to said first signal pulses for producing second signal pulses in accordance with the desired position of said coke transfer car along said track,
• third means responsive to said second signal pulses for moving said coke transfer car along said track,
• fourth means for generating third signal pulses in accordance with the actual position of said coke transfer car along said track, and
• with said third means being responsive to said third signal pulses for modifying the position of said coke transfer car along said track.

The method of controlling the incremental position regulation of a first apparatus in relation to the positional movement of a second apparatus, including the steps of:

• providing first control signal pulses at a rate in accordance with the desired positional movement for said first apparatus,
• controlling the actual movement of said first apparatus in response to said first control signal pulses,
• providing second control signal pulses in response to said first control signal pulses and in accordance with the desired positional movement of said second apparatus,
• providing third control signal pulses in response to the actual positional movement of said second apparatus, and
• controlling the actual movement of said second apparatus in response to at least one of said second control signal pulses and said third control signal pulses.

The method of controlling the movement of a coke transfer car along a track at the coke discharge side of a coke oven chamber in a synchronous relation with the movement of a pusher ram to advance through that coke oven chamber from the opposite side thereof to push coke into said car and form a substantially uniform layer of coke therein, said method including the steps of:

• providing first signal pulses at a predetermined rate for advancing the ram into contact with the coke at one side of the oven chamber and to inhibit the initial movement of said coke transfer car relative to the oven chamber,
• providing second signal pulses in response to said first signal pulses for advancing the coke transfer car along said track in relation to further advancing movement of said ram through said coke oven chamber,
• maintaining movement of the car along the track in a position relationship dependent upon continued forward advancement of said ram through said coke oven chamber, and
• terminating the movement of the car along said track when the ram discontinues said forward advancement through the coke oven chamber.
