  • Patent number: 4667731
    Abstract: A bulk hot coke cooler with a vessel for holding the coolant material and a drum rotatably supported within the vessel so that when the drum rotates, it moves through the coolant, the drum having a plurality of hollow cooling pockets going from one side of the drum to the other which directly contact the hot coke in the drum through which pockets coolant can flow as the drum rotates to enhance the cooling effect of the coolant on the hot coke inside the drum, the pockets having end walls which close off the pockets forming an inlet and an outlet for the coolant, the drum wall not overlapping the pocket end wall. Transfer bars formed integrally of the pockets can be used to facilitate coke movement.

  • Patent number: 4627890
    Abstract: In a centrifugal mass transfer device comprising a rotary annular permeable element, annular plates are mounted adjacent the radially inner or outer face of the permeable element and gaseous or liquid material flowing from the permeable element across one surface of the annular plates is cooled or heated by a heat exchange fluid on the opposite surface of the plates. In this way condensed or vaporized material is returned to the permeable element.

  • Patent number: 4588429
    Abstract: Apparatus and method for the heat processing of granular materials by the counterflow of the granular material and preheated particulate heat exchange media through a processing drum rotatable about an inclined axis. The hot media is intimately mixed with the granular material internally of the drum to heat the material and to cool the media. Various arrangements are disclosed to recover the heat imparted to the material, or to utilize the media for successive heating operations, or to recover waste heat from other related heat processing operations or to utilize the material as preheated by the media.

  • Patent number: 4482096
    Abstract: A cementitious product is produced from a combination of two groups of materials: the first group consisting of lime of Portland cement or Linfan (which is defined as a thermally cracked shell of calcium sulfate surrounding a core of lime) or Linvein (a lime particle coated with cracked calcium carbonate); and a second material consisting of thermally cracked fly ash which is cracked by thermally quenching such finely divided particulate material from an elevated temperature at least above 300.degree. C. and preferably higher than 450.degree. C. to ambient or below ambient temperatures.The two materials are blended together. They are mixed with water, placed in a form, and then allowed to cure. Filler materials can also be used in the form of sand, gravel, and other aggregates, depending upon the strength and compositional characteristics desired in the final product.
