摘要:
An adjustable chargehole closure for adjusting the closure cover of a charging hole in a coking oven chamber. The adjustable chargehole closure has as an inner frame for a closure cover, and the frame can be rotated both with respect to the closure cover and with respect to an outer frame, designed asymmetrically with respect to a vertical plane, so that the closure cover is displaced along a longitudinal axis when the inner frame is rotated in the horizontal plane. The position of the charging hole opening and the closure cover present therein on the ceiling of a coking oven chamber can thereby be changed without requiring construction measures on the ceiling of a coking oven chamber. The capability is in particular advantageous in order to match the position of the charging hole cover to the precise charging position of the charging machine.

A wagon for charging coal into a coke oven is provided with a horizontally displaceable traverse on which a vertically displaceable pickup head is mounted. This head is engageable with a cover on an opening in a coke oven to lift off this cover, then displace it laterally out of the way so as to permit filling of the oven through the opening. A T-shaped lever has one arm pivoted to the lower end of a vertically displaceable rod slidingly guided on the traverse. The T-let of this lever carries a feeler rod extending parallel to the displacement direction of the traverse and engageable with a cover when it is seized by the pickup head. A switch coacting with the upper end of this rod is operated only when the feeler engages a cover on the pickup head, in the raised position of this pickup head, so as to indicate to the discharge mechanism of the filling wagon that the cover is indeed removed from the filling opening.

A larry car carrying a vertically movable lid lifting device is positionable over a row of charging lids on a coke oven. Fluid actuated cylinders actuate the pivoting cooperative lifting arms that grasp and raise a lid so that coal, moving by means of a screw feeder, flows through a closed conduit into the coking chamber. The apparatus is actuated then to replace and seat the lid.

A seat system for a coke drum deheading valve can include a groove in the surface of the seat for supplying a lubricant to the surface of the seat. Various channels can be formed in the body of the seat that connect to the groove. In this way, lubricant can be flowed through the channels and into the groove to provide lubrication between the surface of the seat and the blind. The seat system can also include a split ring packing gland to facilitate the formation of a seal within the deheading valve. The split ring packing gland can be used to retain and compress packing positioned between a retaining ring and a dynamic seat such that when the packing is compressed, an improved seal is formed. By improving the seal, less steam can be required during the delayed coking process thereby increasing the efficiency of the system.
摘要:
A controlled kiln and manufacturing system for biochar production, including control systems and subsystems. An example controlled kiln (100) includes a drum (200), a lid (120) and a floor (250) together forming a combustion chamber configured to contain feedstock for conversion into biochar. A catalytic converter (700) may be operatively coupled with an outlet of the kiln (100). A conversion process completion detection subsystem may be operative to issue notifications. An example biochar manufacturing system includes at least one of the controlled kilns (100), a feedstock filling station (1010, 1020, 1030) for providing feedstock to kiln 100, a firing line (1040) for receiving the kiln containing feedstock, a tipping station (1050) for receiving biochar from the kiln, a biochar sizing station, and an automated handler (800) configured to move the kiln between the feedstock filling station (1010, 1020, 1030), the firing line (1040) and the tipping station (1050).

摘要:
An apparatus and method for raising, moving and lowering a massive coker chute cover are provided. One embodiment of the invention comprises engaging the cover with a lift plate, raising the lift plate, and, moving the lift plate, the course of the movement being in the arc of a circle, lowering the lift plate, and releasing the cover from the plate.
摘要:
A first lever is pivotally secured to the larry car above the coal discharge chute. A second lever is pivotally connected adjacent one end to an arm potion of the first lever. The second lever depends downwardly from the first lever adjacent the coal discharge chute and has an arcuate intermediate portion that positions the second lever other end portion beneath the discharge chute. An electromagnet is secured to the depending end of the second lever and is arranged to magnetically engage the charging hole cover. The pair of levers are so arranged that pivoting of the first lever first moves the second lever depending end portion with the electromagnet secured thereto in a vertical direction to lift the charging hole cover from the charging hole and thereafter in a lateral direction to move the charging hole cover from beneath the coal discharge chute.
