Patent number: 9669351Abstract: A method for more efficiently removing pollutant gases from flue gases of a solid-fueled steam generator includes storing a silo a carbonaceous sorbent in a powdered form; extracting a superheated steam from a superheated steam source; and reducing a temperature, pressure and moisture content of the superheated steam to provide a processed steam of a desired pressure, temperature and moisture content. The method further includes providing a sorbent mill receiving the carbonaceous sorbent and the processed steam, wherein the sorbent mill is operable to de-agglomerate and comminute the carbonaceous sorbent using the processed steam to provide a processed sorbent. Further the method includes injecting the processed sorbent into the flue gases at a desired location in the solid-fueled steam generator thereby adsorbing the pollutants therefrom; and collecting and thereby remove the carbonaceous sorbent from the flue gas fluidly downstream from the desired location.Type: GrantFiled: March 24, 2016Date of Patent: June 6, 2017Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Richard C. LaFlesh, John Iovino, Shin G. Kang, Carl D. Edberg, Raymond W. Cournoyer

Patent number: 9321002Abstract: A system for removing gaseous pollutants, such as mercury from flue gases of a solid-fueled furnace (17), includes a sorbent mill (34) that receives superheated steam and a sorbent (28), such as activated carbon, in a partially agglomerated state, that processes the sorbent (28) by de-agglomerating and comminuting the sorbent (28). An educator (35) transports the processed sorbent (28) to a distributor (36) that injects it into the flue gases at a contact location having a temperature between 500° F. and 900° F., whereupon the sorbent (28) adsorbs mercury from the flue gas. A particle collection device (24) removes the processed sorbent (28) having adsorbed mercury, from the flue gas.Type: GrantFiled: July 19, 2012Date of Patent: April 26, 2016Assignee: ALSTOM Technology LtdInventors: Richard C. LaFlesh, John Iovino, Shin Gyoo Kang, Carl D Edberg, Raymond W. Cournoyer

Patent number: 9205430Abstract: A steam mill system for transport of powdered activated carbon (PAC) from a storage silo to a steam powered jet mill to produce milled sorbent for use in a coal-fired power plant flue gas for mercury control. More specifically, the present disclosure relates to a cyclone separator arranged in a PAC transport line prior to a steam powered jet mill for separation of PAC according to particle size for the purpose of achieving reductions in associated compressed air usage, operating costs and capital costs.Type: GrantFiled: June 5, 2013Date of Patent: December 8, 2015Assignee: ALSTOM Technology LtdInventors: Carl David Edberg, Raymond W. Cournoyer, Richard C. Laflesh, Timothy Joseph Braun

Publication number: 20020132203Abstract: A gas pipe ignitor 10 is provided which is operable to ignite a non-premixed air and fuel mixture and includes an air supply conduit 20 which has an axis ASL, a supply end 22, and a flame end 24 axially spaced from the supply end 22. The gas pipe ignitor also includes a fuel supply conduit 26 extending axially interiorly within at least a portion of the air supply conduit 20 and having an entrance end 28 and an exit end 30. The gas pipe ignitor further includes two branch passages 32 each communicated with the fuel supply conduit 26. The gas pipe ignitor also includes a deflector body 38 disposed in the air supply conduit 20 and is configured relative to the air supply conduit 20 such that air flowing in the air supply conduit 20 flows along a pass through passage PTP from upstream of the upstream most surface 40 of the deflector body 38 to downstream of the deflector body 38.Type: ApplicationFiled: March 19, 2001Publication date: September 19, 2002Applicant: ALSTOM (Schweiz) AGInventors: Carl D. Edberg, Raymond D. MacWhinnie, David J. Matteson, Raymond W. Cournoyer

Patent number: 5947110Abstract: The pressure pulsations caused by the flow patterns of flue gases entering a flue gas stack from a horizontal duct are eliminated or reduced by the installation of a partition plate in the stack opposite the inlet duct. This negates the adverse interaction of the two vortices in the stack formed by the entering flue gases and allows the vortices to travel independently up the stack.Type: GrantFiled: October 25, 1996Date of Patent: September 7, 1999Assignee: Combustion Engineering, Inc.Inventors: Mark R. Malo, Raymond W. Cournoyer, James M. Niziolek
