Moist bulk coal is supplied into a fluidized bed drier into which is introduced a first heat carrier gas to thereby dry the moist coal to form dried coal. The dried coal is discharged from the drier and is transferred to a generally horizontal bulk material conveyor. A second heat carrier gas is injected through the bottom of the bulk material conveyor, thereby transporting the coal generally horizontally and preheating the coal to form preheated coal. The preheated coal is then discharged from the bulk material conveyor and is filled into a selected charging opening of a coke oven battery.

Method of preheating coal and supplying preheated coal to a coke oven

An apparatus for charging coke chambers is disclosed which effectively reduces and controls gas and dust emissions evolved during the coke charging operation. The charging apparatus includes a gas-tight enclosure which seals the immediate area surrounding the cooling chamber or serially arranged chambers in a cooling plant, a lift transport facility located internally to the enclosure for carrying a coke bucket to and from the respective coke cooling chambers, a crane or elevator for placing and removing the coke bucket from the lift transport facility, and an exhaust device for evacuating the gas and dust emissions from the enclosure. Inert gas feedlines are integrated with the charging operation to maintain an inert gas atmosphere within the enclosure.

Charging apparatus for coke cooling chambers

In the process of transferring coke from a coke oven chamber in a battery of coke ovens to a quenching car, the coke is quenched by a water spray from above. The resulting steam is collected in a hood located above and movable with the quenching car and is either exhausted from the hood and conveyed to a condenser or is condensed in the hood with the condensate being collected, cooled and recirculated to provide the water for the quenching and condensing sprays. The apparatus and method of this invention provides for transferring and quenching the coke without emitting harmful gases and dust to the atmosphere.

Apparatus for the transfer and quenching of coke

A method and apparatus for the dry cooling of coke is disclosed wherein a cooling gas is routed through a coke charge by means of a distributor or manifold disposed in the bottom of a vertical cooling chamber. The gas passing upwardly through the coke charge is heated by the hot coke. A temperature sensor is provided in the discharge line for the heated gas from the coke cooling chamber, and the distribution and flow rate of the cooling gas introduced at the bottom of the chamber is controlled thereby to maintain a predetermined temperature of the discharged gas. A further embodiment includes multiple gas discharge lines located at different levels of the coke charge. Since the temperature of the gas discharged varies with the level from which the gas is withdrawn, controlled combination of the various discharge flows provides an additional means for producing and maintaining the predetermined temperature of the combined gas discharge.

Dry cooling of coke

A method and an apparatus are described for preventing the unintentional introduction of coal from a supply into a coke oven which already contains a charge of coal or coke. An obstruction sensor is lowered through a charging hole in the ceiling of the oven; if it encounters an obstruction, such as a charge of coal or coke in the oven, it triggers a signal which blocks any discharge of coal through the charging hole into the oven.

Method of, and apparatus for preventing the unintended charging of coke

An apparatus for the dry cooling of coke is disclosed including a vertical cooling chamber having an open bottom, a gas distribution manifold disposed in the bottom of the cooling chamber and a pair of discharge openings for the continuous withdrawal of the cooled coke from the bottom of the chamber. The cooling gas manifold includes upwardly sloping walls which intersect at an apex located generally centrally of the bottom of the cooling chamber. Gas discharge openings extend through these walls and are so disposed as to make cooling gas available across the entire cross-section of the cooling chamber. Individual, closed gas chambers communicate with groups of the gas discharge openings and the flow of gas to each chamber is individually regulated. Temperature sensing means is provided in the cooling chamber and the flow of cooling gas to the individual gas chambers is controlled in response to the temperatures sensed in the cooling chamber to achieve an even cooling distribution throughout the cooling chamber.
