    Abstract: Apparatus for cleaning high temperature, high pressure gases includes a pressure vessel, and a filtration unit within the pressure vessel. The filtration unit is adapted to communicate with a fluidized bed reactor gas outlet, and includes at least one dirty gas chamber housing a plurality of porous, ceramic filter tubes, and at least one clean gas chamber for receiving clean gas from the ceramic filter tubes. The dirty gas chamber includes a particle outlet for removing particles separated from the gas by the filter tubes. The porous ceramic filter tubes are horizontally oriented within the filtration unit or housing and mounted within water cooled walls of the housing. The fluidized bed reactor and associated cyclone separator may be located within the pressure vessel with the filtration unit, or located outside the pressure vessel and in communication with the filtration unit inside the pressure vessel.

    Abstract: The grid plate is disposed between the fluidized bed reactor chamber and an underlying wind box and includes a plurality of nozzles for feeding fluidizing gas from the wind box into the reaction chamber. The nozzles are configured to afford different pressure drops across the grid such that with increasing pressure, additional nozzles are actuated in response to increasing pressure differences across the plate whereby fluidized bed start-up and steady state operating conditions may be facilitated.

    Abstract: In accordance with the present invention, there is provided a filter housing comprising a plurality of open-ended parallel hollow gas permeable filter elements for separating particulate material from a high-temperature gas. The filter housing comprises at least a pair of cross sectional support plates having apertures therethrough, for dividing the filter housing into at least three sections and for supporting the filter elements. The support plates divide the filter housing into a first end section having an inlet for dirty gas, a second end section in connection with a discharge port for separated particulate material, and an intermediate filtration chamber section therebetween. The filter elements are arranged in the intermediate filtration chamber extending from the first support plate to the second support plate. The end portions of the filter elements are affixed to the apertures through the support plates. Inlet openings of the filter elements are arranged in communication with the first end section of the filter housing, for introducing dirty gas into the filtration elements. Outlet openings of the filter elements are in communication with the second end section, for discharging separated particulate material from the filter elements. A clean gas outlet conduit is in communication with the clean gas space in the intermediate filtration chamber, for discharging clean gas from the filter housing. It is an important feature of the present invention that means are provided inside said filter housing for supplying a reverse flow pressure pulse of high energy gas into said filtration chamber, for cleaning the porous filter medium. The reverse-flow pressure pulse can be supplied through a relatively small pipe connected to a compressor.

    Abstract: Either atmospheric pressure or superatmospheric pressure high temperature gases, as from a gasifier or other circulating fluidized bed reactor, are filtered using monolithic ceramic filter elements mounted in an advantageous manner within a vessel. At least one generally upright hollow chamber element is mounted by a tube plate within the vessel, and has at least one gas impervious side wall having a column of openings in it, an open end, and a closed end. Monolithic ceramic filter elements are mounted in the openings. A number of chamber elements are typically provided, e.g. mounted in a circular pattern, and/or mounted to extend downwardly from a top tube plate and upwardly from a bottom tube plate. Backflushing of the filter elements dislodges separated particles, which fall down to the bottom of the vessel and are removed through a central discharge opening.

    Abstract: A pressurized fluid bed reactor power plant includes a fluidized bed reactor contained within a pressure vessel with a pressurized gas volume between the reactor and the vessel. A first conduit supplies primary gas from the gas volume to the reactor, passing outside the pressure vessel and then returning through the pressure vessel to the reactor, and pressurized gas is supplied from a compressor through a second conduit to the gas volume. A third conduit, comprising a hot gas discharge, carries gases from the reactor, through a filter, and ultimately to a turbine. During normal operation of the plant, pressurized gas is withdrawn from the gas volume through the first conduit and introduced into the reactor at a substantially continuously controlled rate as the primary gas to the reactor. In response to an operational disturbance of the plant, the flow of gas in the first, second, and third conduits is terminated, and thereafter the pressure in the gas volume and in the reactor is substantially simultaneously reduced by opening pressure relief valves in the first and third conduits, and optionally by passing air directly from the second conduit to the turbine.

    Abstract: A filter assembly for high temperature gases, such as from a circulating fluidized bed reactor, mounts monolithic ceramic filter elements within an upright vessel so that as the hot gas flows from the top toward the bottom of the vessel the gas passes through the elements with the clean gas discharged through a side wall of the vessel. The particle discharge is provided at the bottom of the vessel. Filter supporting elements within the vessel are cooled by cooling fluid, and pulse cleaning elements are associated with each of the filter elements. Flow directing elements within the vessel typically define a generally conical or pyramidal shaped flow directing surface. The flow directing elements may be refractory material bodies, or funnel shaped thin elements (e.g. of metal capable of withstanding high temperature), and may be mounted so that small amounts of movement are possible to accommodate thermal contraction or expansion.
