US Patent:

20090208397, Aug 20, 2009
Filed:

Feb 16, 2009
Appl. No.:

12/371705

George D. Mylchreest - Simsbury CT, US
Assignee:

ALSTOM Technology Ltd - Baden
International Classification:

B01D 53/50
B01D 53/06
US Classification:

42324407, 96138, 96 55, 422169, 95107
Abstract:

A system for removing sulfur dioxide (SO) from SOladen flue gas resulting from the burning of fossil fuel, includes an absorber and first and second separators. The absorber captures SOfrom a flow of the SOladen flue gas with a sorbent. The first separator separates a first portion of the sorbent with captured SOboth from a second portion of the sorbent with captured SOand from the flue gas. The second separator separates the second portion of sorbent from the flue gas.

US Patent:

20120145052, Jun 14, 2012
Filed:

Nov 16, 2011
Appl. No.:

13/298147
Inventors:

Armand A. Levasseur - Windsor Locks CT, US
Shin G. Kang - Simsbury CT, US
James R. Kenney - Windsor CT, US
Carl D. Edberg - Stafford Springs CT, US
David G. Turek - South Windsor CT, US
Assignee:

ALSTOM TECHNOLOGY LTD. - Baden
International Classification:

F23B 80/02
F23C 9/00
F23L 7/00
US Classification:

110341, 110234, 110205
Abstract:

Disclosed herein is a method of controlling the operation of an oxy-fired boiler; the method comprising combusting a fuel in a boiler; producing a heat absorption pattern in the boiler; discharging flue gases from the boiler; recycling a portion of the flue gases to the boiler; combining a first oxidant stream with the recycled flue gases to form a combined stream; splitting the combined stream into several fractions; and introducing each fraction of the combined stream to the boiler at different points of entry to the boiler.

US Patent:

20120178030, Jul 12, 2012
Filed:

Dec 20, 2011
Appl. No.:

13/331234
Inventors:

Shin G. Kang - Simsbury CT, US
Armand A. Levasseur - Windsor Locks CT, US
Robert A. Schrecengost - Avon CT, US
Assignee:

ALSTOM TECHNOLOGY LTD - Baden
International Classification:

F24H 9/00
F24H 1/00
US Classification:

431 2, 431192
Abstract:

A system and method for reducing emissions from a boiler. A boiler generally has a combustion area. The system further includes a fuel pipe for delivering fuel. The system further includes a conduit. A bore extends through the conduit. The bore of the conduit is in fluid communication with the fuel pipe and the combustion area of the boiler. A pre-ignition source is positioned in the conduit. The pre-ignition source operates to pre-ignite at least a portion of the fuel flowing through the conduit.

Assignee:

ALSTOM TECHNOLOGY LTD - Baden
International Classification:

A23G 9/28
US Classification:

137 1, 137602
Abstract:

A system for treating an effluent stream including a carbon capture system utilizing an amine-containing solution to remove carbon dioxide from a flue gas stream, the carbon capture system generating an effluent stream comprising degradation products generated by the amine-containing solution; storage means for storing at least a portion of the effluent stream, the storage means being fluidly coupled to the carbon capture system. The system also including at least one nozzle connected to a combustion zone of a boiler, the at least one nozzle being fluidly coupled to the storage means for providing at least a portion of the effluent stream present in the storage means to the combustion zone of the boiler through the at least one nozzle, wherein the effluent stream provided to the combustion zone is co-incinerated with a fuel in the combustion zone.

F22B 33/00
F01K 3/24
F01K 7/32
F01K 11/02
F01K 19/00
Abstract:

A system for providing supercritical steam including a first boiler that generates steam via combusting a first fuel, and a second boiler fluidly connected to the first boiler via a conduit which heats the generated steam to supercritical steam temperatures via combusting a second fuel. A first temperature of the conduit may be below a critical corrosion temperature and a second temperature of the conduit is greater than or equal to the critical corrosion temperature. A combined carbon emission rate of the first boiler and the second boiler may be less than a combined carbon emission rate of generating and heating the steam to supercritical steam temperatures using boilers that only combust the first fuel. The first boiler may be fluidly connected to a heat exchanger that heats the generated steam to a supercritical steam temperature via a flue gas produced by a gas turbine.
