    • 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 Since the temperature of the gas discharged varies with the level from which the gas is withdrawn, controlled combination of the various discharge flows provides an additional means for producing and maintaining the predetermined temperature of the combined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.
    • 公开了一种用于干燥冷却焦炭的方法和装置,其中冷却气体通过设置在垂直冷却室底部的分配器或歧管通过焦炭装置。 向上通过焦炭装料的气体被热焦炭加热。 在来自焦炭冷却室的加热气体的排出管路中设置有温度传感器,并且控制在室底部引入的冷却气体的分布和流量,从而保持排出气体的预定温度。 另一实施例包括位于焦炭装料的不同水平的多个气体排放管线。 由于排出的气体的温度随着气体的排出水平而变化,所以各种排放流的控制组合提供了用于产生和保持组合气体排放的预定温度的附加装置。

    • Coal is passed in a two-stage process through a drying and heating zone. The coal coming from the drying zone is separated from the heat carrier gas which is then passed into the atmosphere after going through an electrodust separator. The dried coal is delivered into the heating zone. The hot gas for the heating zone is furnished by a combustion device. The exhaust gas from the heating zone is separated from the heated coal which is recovered while the exhaust gas is passed back into the drying zone. Part of the hot combustion gas coming from the combustion chamber is branched off and passed into the exhaust gas coming out of the drying zone either directly behind the drying zone or behind the separator for separating the dried coal from the exhaust gas. The temperature of the exhaust gas from the drying zone is thus prevented from sinking below the sulfuric acid dewpoint or water vapor dewpoint which might result in corrosive damage to the apparatus, particularly to the electrodust separator.
    • 煤通过干燥和加热区在两阶段过程中通过。 来自干燥区的煤与热载体分离,然后通过电极分离器后将其通入大气中。 干燥的煤被输送到加热区。 加热区的热气由燃烧装置提供。 来自加热区域的废气与废气再次返回到干燥区域中被回收的加热煤分离。 来自燃烧室的热燃烧气体的一部分被分支并且从干燥区域直接排出干燥区域的废气或分离器之后的废气中,从而将干燥的煤与废气分离。 因此,防止来自干燥区域的废气的温度低于硫酸露点或水蒸气露点,这可能导致对设备,特别是电极分离器的腐蚀性损坏。
