摘要： A method and apparatus for reducing and removing mercury in industrial gases, such as a flue gas, produced by the combustion of fossil fuels, such as coal, adds sulfide ions to the flue gas as it passes through a scrubber. Ideally, the source of these sulfide ions may include at least one of: sulfidic waste water, kraft caustic liquor, kraft carbonate liquor, potassium sulfide, sodium sulfide, and thioacetamide. The sulfide ion source is introduced into the scrubbing liquor as an aqueous sulfide species. The scrubber may be either a wet or dry scrubber for flue gas desulfurization systems.

摘要： An annular heat-exchange reactor vessel allows for selectively controlled heat transfer between a first fluid and second fluid flowing through the vessel. Optionally, catalyst means may be added to further convert either fluid into a desired end product. In this regard, it is envisioned that the present invention will have particular utility in fuel processing systems. Additional, in-line upstream or downstream annular modules may also be incorporated to create a more complete, efficient and/or compact system. Various methods for constructing this reactor system are also disclosed.

摘要： An EMAT arrangement utilizes separate transmitter and receiver EMATs which may each be connected to a tuning capacitor by a stripline cable. An electrostatic shield may also be provided between the coils and the coils can be offset from each other by 1/2 the pitch distance of sections in the coil. This reduces the duration of main bang, thus making it possible for the EMAT arrangement to detect structures which are very close to the coils.

摘要： An improved Cyclone furnace particularly suitable for retrofit applications to an existing boiler incorporates a Cyclone furnace and an integrated de-slagging chamber as a single manufactured piece. The Cyclone furnace and the de-slagging chamber are provided with a water cooling circuit which is separate from a water cooling circuit of the existing boiler to which it may be coupled, permitting the improved Cyclone furnace to be easily retrofitted to existing boilers or furnaces, even those not originally designed for Cyclone firing.

摘要： A wire cleaner having a chamber and containing an arc ring for passing a wire therethrough, such that when the wire and arc ring are provided with opposite electrical potentials, an electric arc discharge occurs from the wire to the arc ring which carries off impurities from the surface of the wire. An inert gas is used to purge the chamber to prevent oxidation of the wire during and following the discharge from the wire. A pair of annular permanent magnets are positioned around the wire on each side of the arc ring to produce a magnetic field parallel to the wire which interacts with the electrical arc discharge and causes the arc to rotate around the circumferences of the wire and arc ring, thereby cleaning the entire wire. A second embodiment is provided in which the pair of permanent annular magnets is replaced by a variable strength electromagnet surrounding the arc ring and wire path. Other embodiments employ a pair of arc rings to carry the electric current so that two arcs are created in tandem. Alternating current (AC) with a superimposed high frequency (HF) current can be used to stabilize the arcs, which then rapidly alternate between the wire and each of the two arc rings. The pair of arc rings share a more powerful permanent magnet between them, with second and third permanent magnets located outboard of each arc ring. An internal wire guide can be used to prevent the wire from contacting the arc rings.

摘要： An air sparger assembly for a flue gas desulfurization wet scrubber agitation tank that eliminates the need for a mixer and reduces the amount of piping required. The air sparge pipes are arranged to be concentric with the agitation tank. A single main header provides air to the air sparge pipes. The discrete location of the air discharge holes in the sparge pipes utilizes the buoyant energy of the oxidation air to mix the slurry in the agitation tank.

摘要： An integrated reburn system for a cyclone-fired boiler has a reburn fuel feed nozzle through a cyclone burner into the cyclone barrel, or furnace, at a region of low-velocity fuel and air movement. The reburn fuel is injected at high velocity and mostly does not mix with the combustion fuels and gases within the cyclone barrel. The reburn fuel passes through the re-entrant throat of the cyclone into the main furnace, where it forms a reburn zone having a reducing atmosphere in which the reburn fuel reacts with combustion gases from the main combustion zone to convert NO.sub.x to N.sub.2, thereby reducing the amount of NO.sub.x emissions produced by the furnace.
