    Abstract: There is provided a process for converting wet fly ash into a useful product such as cement replacement or industrial filler. A first amount of wet fly ash is provided. The wet fly ash is fed into a mixing chamber. An amount of aggregate, such as stone, is provided. The aggregate is also fed into the mixing chamber where the wet fly ash is mixed with the aggregate. The mixed wet fly ash and aggregate is fed into a drying chamber where the mixture is heated, thereby drying the fly ash and heating the aggregate. The heated aggregate is separated from the fly ash. The heated aggregate is fed back into the mixing chamber. A second amount of wet fly ash is added to the mixing chamber where is it mixed with the heated aggregate. The heated aggregate assists in drying the second amount of wet fly ash. Once in cycle, the process is continuous. Preferably, after the dried fly ash is segregated from the heated aggregate, it is introduced to a burner where the carbon component is oxidized and the beneficated fly ash exits.

    Abstract: In order to separate a carbon-containing fraction as completely as possible from a residue, for example a pyrolysis residue, a combustible constituent is first separated from a non-combustible constituent. A carbon-containing light fraction is subsequently separated from a small-fragment fraction of the non-combustible constituent. For this purpose, in a preferred embodiment, a combination of a facility for the separation of wire with a heavy-fragment separator following the latter is provided for a continuous separation operation. The carbon-containing fraction thus obtained is preferably supplied for further utilization to a combustion chamber of a pyrolysis plant.

    Abstract: A process for removing ammonia from fly ash during processing on an inclined fluidized bed. The process begins by introducing a mixture of particulates having ammonia adsorbed therein into an inclined fluidized bed. Concurrently, a fluidizing gas is pre-heated and is also introduced into the fluidized bed. The mixture is then processed along the fluidized bed with the pre-heated fluidizing gas to achieve bubbling fluidization of the particles. This causes segregation by which a dense fraction settles downward and a light fraction rises upward in the bed. Ammonia in the particles is desorbed by the pre-heated fluidizing gas. The fluidizing gas is then scrubbed after the processing step to remove the desorbed ammonia. The process may also include the use of acoustic enhancement whereby an acoustic field is imposed on the fluidized bed to improve fluidization and segregation of the particles and to increase the efficacy of ammonia removal. In addition, a heat exchanger or electric heating elements immersed in the fluidized bed can be used to heat the ash to the temperatures needed to desorb ammonia from the ash. Furthermore, the energy efficiency of the process can be improved by recovering heat from the hot ash discharged from the fluidized bed and/or from the exhaust stream of hot fluidizing gas, for reuse during preheating steps. The improved process removes ammonia in a simple and efficient manner by preheating the fluidizing gas of the inclined bed to temperatures of 300 to 500° F., and using this preheated gas to drive off any adsorbed ammonia.
