Publication number: 20100083834Abstract: Fine, solid particles in a gas stream, especially fly ash particles in the hot gas stream from a coal/coke-utilizing synthesis gas unit, are agglomerated by passage through a gas flow matrix element having a body with confined gas flow channels which bring the particles into close proximity to one another in an environment of low turbulence; a rough surface on the gas flow passages provides surface induction to promote agglomeration of the particles. The larger, agglomerated particles may then be removed from the gas stream by inertial separators such as cyclones.Type: ApplicationFiled: September 29, 2009Publication date: April 8, 2010Inventor: Ramesh Varadaraj

Patent number: 7678165Abstract: A particle separator which broadly includes: an inner wall, an outer wall and a splitter, wherein the inner and outer walls define an air intake passageway, and wherein the splitter is positioned between the inner and outer walls so as to define a scavenge air flow passageway connected to the intake passageway and a main air flow passageway connected to the intake passageway; the inner wall having a humped-shaped portion between the intake passageway and the main air flow passageway; the humped-shaped portion having a peak and a radius of curvature at any point on the hump-shaped portion of the inner wall after the peak corresponding to a degree of curvature of from about 30 to about 60 degrees; and a boundary layer control mechanism for providing active boundary layer control along the inner wall after the peak and within the main air flow passageway. Also provided is a method for providing active boundary layer flow control along the inner wall after the peak and within the main air flow passageway.Type: GrantFiled: December 28, 2006Date of Patent: March 16, 2010Assignee: General Electric CompanyInventors: Walter Jackson Tingle, Wayne R.

Publication number: 20100000409Abstract: A method and apparatus for practicing the method are provided for separating droplets of finely aerosolized elemental mercury from a gaseous stream in which the droplets are dispersed. In the method a gold plated metallic capillary surface is contacted with the gaseous stream, causing the aerosolized droplets to deposit on the capillary surface and by capillary action to coalesce with other of such droplets to form increasingly large drops of mercury. The surface is oriented to allow the mercury to flow by gravitational forces and capillary action to the lowermost portions of the surface, at which it accumulates, and is then collected at a suitable vessel.Type: ApplicationFiled: June 30, 2009Publication date: January 7, 2010Inventor: Hal Alper

Patent number: 7575616Abstract: Embodiments of the present invention provide low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity.Type: GrantFiled: February 10, 2006Date of Patent: August 18, 2009Assignee: Entegris, Inc.Inventors: Anthony DiPrizio, Nathan Abbott, Christopher Vroman, Rajnikant B.

Patent number: 7556674Abstract: A device (16) for separating particles (MP) from a flue gas flow (F) has a horizontal flue gas duct (18), through which the flue gas flow (F) is passed substantially horizontally from a first position (P1) to a second position (P2). In the first position (P1), the device (16) has a baffle arrangement (32), which comprises at least one plate (34, 36, 38) which is arranged in the flue gas duct (18) and which is inclined so as to deflect particles (MP) down to the lower portion (42) of the horizontal flue gas duct (18). In the second position (P2), the device (16) has a collecting means (40), which is arranged in the lower portion (42) of the flue gas duct (18) to collect the particles (MP) which have been deflected downwards by the plate (34, 36, 38) to the lower portion (42) of the flue gas duct (18).Type: GrantFiled: May 20, 2005Date of Patent: July 7, 2009Assignee: ALSTOM Technology LtdInventor: Rune Andersson
