Abstract: 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.

Abstract: 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 Since the temperature of the gas discharged varies with the level from which the gas is withdrawn, controlled combination of the various discharge flows provides an additional means for producing and maintaining the predetermined temperature of the combined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.

Abstract: 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.
