    摘要： A process for recovering the byproducts of a process that burns coal and for reusing the byproducts is disclosed. The process includes the steps of identifying a disposal site that contains the byproducts (typically fly ash and bottom ash), removing at least a portion of the byproducts from the disposal site, analyzing a sample of the portion of the byproducts to determine the loss on ignition of the portion of the byproducts, introducing the portion of the byproducts along with pulverized coal into a pulverized coal furnace if the portion of byproducts have a loss on ignition greater than or equal to a predetermined loss on ignition value (typically greater than or equal to 1 to 5 %), and burning the portion of the byproducts in the furnace with the pulverized coal to render the byproducts into a commercially valuable fly ash and bottom ash having very low loss on ignition, typically lower than 3 %.

    摘要： Compositions are provided for increasing the electrical conductivity of concrete or controlled low-strength materials (flowable fill). One composition sets to produce a concrete and includes portland cement, water, aggregate, and particulate matter including a sorbent and a contaminant absorbed, adsorbed or entrapped by the sorbent. The sorbent may be activated carbon, and the contaminant may be mercury or a compound containing mercury. Another composition is a self-compacting, cementitious flowable fill composition that includes portland cement, water, and particulate matter including a sorbent and a contaminant absorbed, adsorbed or entrapped by the sorbent. The sorbent may activated carbon, and the contaminant may be mercury or a compound containing mercury. The compositions may also include carbon fibers.

    摘要： A method and apparatus for the application of heat to remove ammonia compounds from fly ash, thereby making the fly ash a marketable product is disclosed. The method includes the steps of providing an amount of fly ash wherein at least a portion of the amount of fly ash comprises particulates having ammonia compounds affixed to the particulates, and exposing the fly ash to flowing air having a temperature of at least 1,500 °F (815 °C) such that the fly ash is maintained in the flowing air until the fly ash reaches a temperature of at least 900 °F (482 °C). The apparatus (8, 9) includes a source of fly ash (10) comprising particulates having ammonia compounds affixed to at least some of the fly ash particulates, a heating chamber (17) including a treatment bed comprising a floor (20) having openings, a fly ash supply conduit (16) in communication with the heating chamber (17) and the source of fly ash (10) for transferring fly ash from the source of fly ash to the treatment bed of the heating chamber, a source of heated air (45), an air supply conduit (55) in communication with the source of heated of heated air (45) and the heating chamber (17) for providing a flow of heated air to the treatment bed of the heating chamber for contacting the fly ash on the treatment bed with the flow of heated air, a heated air conduit (27) in communication with the heating chamber (17) for transferring the flow of heated air form the heating chamber, and an ash removal conduit (31) in communication with the heating chamber (17) for transferring heated fly ash from the heating chamber.

    摘要： Compositions for producing electrically conductive controlled low-strength material and electrically conductive concrete are provided, comprising conventional components, but utilizing a non-standard, high carbon content, fly ash. One settable controlled low-strength material composition includes 1%-20% by weight of portland cement, 18%-85% by weight of fly ash having a carbon content of greater than 12%, and water such that the composition sets to a material having a compressive strength of 8.3 MPa or less. One settable concrete composition includes 1%-30% by weight of portland cement, 1%-20% by weight of fly ash having a carbon content of greater than 12%, 40%-90% by weight of an aggregate, and water such that the composition sets to a concrete having a compressive strength of at least 13.8 MPa.
