    Abstract: Vane type mist eliminator segments are arranged in a plurality of tiers at separate vertically spaced locations in a tower, typically of the upright, cylindrical type, with the eliminator at each tier covering only a portion of the cross section of the tower. The eliminator segment(s) in each tier are laterally displaced in the tower from the adjacent vertically spaced eliminator segments to form a staggered configuration for the segments. Each mist eliminator preferably extends over 50-70% of the cross-sectional area of the tower to leave an open flow passage in the tier; the staggering of the segments and the associated flow passages defines an upward tortuous or zig-zag open flow path for vapors ascending the tower through the open flow passages when the eliminator segment(s) become fouled in use.

  • Patent number: 8097051
    Abstract: A separator for liquids, in particular condensate, from liquid-loaded compressed gases-generally serves, by coarse separation of condensate from the compressed gases, to protect downstream prefilters of cold dryers or adsorption dryers against overload due to condensate. In the separator of the invention, in a pot-shaped housing, a separator element in the form of a hollow cylinder is arranged, which consists of a multiplicity of flow chicanes formed from guiding bodies and impact bodies. The moisture-loaded gases are passed from the interior of the hollow cylinder to the exterior via these flow chicanes, condensate separating off on the chicanes and collecting in the collecting space.

  • Patent number: 8048211
    Abstract: A tank arrangement includes a tank for storing a liquid such as fuel or oxidizer for operation of a spacecraft and a pressurized driving gas for conveying the liquid out of the tank, and a gas supply and extraction device. The device includes a housing shell and plural outwardly expanding passage bodies providing openings that communicate the interior space of the tank to the inner reservoir space of the device. A baffle plate shields the outer opening of each passage body. Deflector plates are arranged in each passage body. Capillary plates extend longitudinally along the inner wall of the housing shell. By a capillary effect, the plates separate liquid from gas entering the device, so that the gas can be extracted while the liquid is stored in a reservoir of the device until it is drained back into the tank during an accelerated operation phase of the spacecraft.

  • Patent number: 8048184
    Abstract: A baffle tool operative to manually install and remove commercial grill baffles and filters has a longitudinally extensive handle. First and second filter plates pivotally attach to the handle and are operative to couple through a set of prongs with a commercial grill filter. An actuating handle is moveable relative to the longitudinally extensive handle. First and second linking rods extend between the filter plates and actuating handle, and transmit motion of the actuating handle to the first and second filter plates. Movement of the actuating handle thereby causes the filter plates to move relative to the longitudinally extensive handle. A lock is also provided for selectively locking the actuating handle to the longitudinally extensive handle and preventing motion therebetween, which facilitates the securement of a baffle to the tool.

  • Patent number: 8047162
    Abstract: A system and method for quickly cooling and de-pressurizing a boiler arrangement in the event of a plant power loss, a.k.a. a black plant condition. A steam discharge system injects steam from the steam/water circuit into the furnace, thereby both cooling components of the boiler arrangement and reducing pressure in the steam/water circuit. This reduces or eliminates the additional cost associated with providing extra capacity in a steam drum and/or an independently powered boiler water pump. The system and method is particularly useful for quickly cooling the U-beams of a circulating fluidized bed (CFB) boiler during a black plant condition. In application to boiler arrangements with a selective non-catalytic reduction (SNCR) system employing steam as a carrier for a NOx reducing agent, the steam discharge system advantageously uses the discharge nozzles of the SNCR system to inject the steam into the furnace.

  • Patent number: 8025721
    Abstract: A gas supply and extraction device is arranged preferably on a tank lid or a tank wall in a tank for storing a pressurized driving gas and a liquid such as fuel or oxidizer for operation of a spacecraft. A device housing defines an interior reservoir space. Upper trumpet-shaped passage bodies and a lower trumpet-shaped passage body communicate from the interior reservoir space into the interior space of the tank. By capillary effects, baffle plates, deflector plates, capillary plates, a separation chamber and other components separate liquid from gas entering the device, so that the gas can be extracted while the liquid is stored in the reservoir space of the device until it is drained back into the tank during an accelerated operation phase of the spacecraft.

  • Patent number: 7981182
    Abstract: A labyrinth box can include a housing that has an open end, a closed end, and defines two cavities. A cover is configured to cover the opening and can include a divider that extends into one of the two cavities of the housing to define first and second chamber passageways in that cavity. An inlet port is located in the bottom closed end of one of the cavities and an outlet port is located in the other of the cavities. The surfaces that define the chambers can be configured such that the box can be oriented in different positions and still work, namely, in horizontal and vertical positions. When in the vertical position, the divider can include surfaces that are angled off of the horizontal plane and towards the inlet port such that water and debris will return to the inlet port via gravity.

  • Patent number: 7955408
    Abstract: This Invention relates to a kind of devices with no emission resulted for treatment of exhaust gas. The Device comprises a vessel having openings that serve only as inlet. At least two exchange sections are provided inside the vessel after inlet of exhaust gas. There is a gas chamber at each connection part between two sequential sections. The gas exchange chamber at the first gas exchange section has a through opening leading to outside atmosphere area, and at each one from the second to the last exchange section, there is a feedback pipe to connect to the inlet of the first stage of exchange section. With this configuration, on entering into the exchange section, exhaust gas will be ejected inwards and causes very strong entrainment, which makes the gas chamber become vacuum and sucks air with oxygen from atmosphere into gas chamber via the through opening to atmosphere.
