    Abstract: The gas from combustion or gasification of fossil fuel contains flyash and other particulate. The flyash is separated from the gas in a plurality of standleg moving granular-bed filter modules. Each module includes a dipleg through which the bed media flows into the standleg. The bed media forms a first filter bed having an upper mass having a first frusto-conical surface in a frusto-conical member at the entrance to the standleg and a lower mass having a second frusto-conical surface of substantially greater area than the first surface after it passes through the standleg. A second filter media bed may be formed above the first filter media bed. The gas is fed tangentially into the module above the first surface. The flyash is captured on the first frusto-conical surface and within the bed mass. The processed gas flows out through the second frusto-conical surface and then through the second filter bed, if present. The bed media is cleaned of the captured flyash and recirculated to the moving granular bed filter. Alternatively, the bed media may be composed of the ash from the combustion which is pelletized to form agglomerates. The ash flows through the bed only once; it is not recycled.

    Abstract: The present invention provides an improved design for the hindered settling bed within a mineral jig. The hindered settling bed contains relatively low density materials that can be used in conjunction with high density materials to aid in the separation of particulate materials within the mineral jig. The presence of the relatively low density barrier materials in the settling bed allow for the separation to occur with less channelling of the separated material through the bed area.

    Abstract: A fluidized bed reactor (10) for chemically transforming reactants to generate a desired product, having a hollow, elongated, vertically oriented reactor housing (12) for confining the reaction and an unobstructed collection path (18) below the reaction zone for funneling the residue of the process to an exit port (32). A central gas inlet (22) proximate the bottom of the reaction zone within the housing directs gas parallel to the vertical axis of the housing to maintain the raw materials in suspension. A plurality of individually controlled peripheral gas jets (24) positioned at least two elevations along the elongated dimension of the reaction housing (12), and located circumferentially around the housing (12) at each elevation, introduce gas at an angle to promote mixing of the entrained materials in suspension. The clog-free collection path (18) below the reaction zone funnels the residue of the process to an exit port (32) where it is continuously removed by a screw feeder (34). A gas sparger (30) below the reaction zone diverts fine agglomerates of the residue back into the reaction stream to increase the efficiency of the process and minimize the residue.

    Abstract: A moving granular bed filter for removing contaminants from a gas or vapor stream employs a quantity of granular media that is passed through a vessel while the contaminant-laden gas stream is passed through the granular media to remove at least a portion of the contaminants from the gas stream and into the granular media. The vessel includes a media inlet that extends between a pair of opposite regions of the vessel and delivers the granular media into the interior of the vessel such that the granular media forms a freely-formed filtration pile within the interior of the vessel to define first and second chambers above the upper surface of the pile and on opposite sides of the media inlet. In one embodiment, the media inlet is disposed at the lower end of a media delivery channel that extends downwardly into the interior of the vessel and which supplies the granular media to the media inlet. In the same embodiment, the vessel additionally includes a gas flow direction plate disposed within the media and extending between the pair of opposite regions of the vessel to direct the flow of the gas stream both concurrent and then counter-current with the flow of the granular media through the vessel. In another embodiment, the vessel does not include the gas flow direction plate. In still another embodiment, the media delivery channel may include a flared skirt that forms the media inlet. The abstract shall not be used for interpreting the scope of the claims.

    Abstract: The high temperature particle velocity meter is comprised of a pair of spaced apart conducting portions having disposed on each of their upstream edges a first and second non-conducting portion. The bombardment of the particles on the conducting and non-conducting portions creates charged particles in the pneumatically transported material. These particles discharge an electric current through the conducting portions to respective conductors and then to respective signal generating means. The signal generating means convert the electric discharges to an electronic signal. The electronic signals from each of the signal generating means are fed into a calculating means which calculate the particle velocity of the material based on the respective electronic signals. In another embodiment, the device can be used in a ceramic pipeline or a metal pipeline having its inner surface ceramically lined. In this embodiment, the device does not include the non-conducting portions as the pipe is already non-conducting. An associated method is also disclosed for each type of pipeline.
