Filed:

Feb 16, 2009

Appl. No.:

12/371705

Inventors:

Armand A. Levasseur - Windsor Locks CT, US
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.

International Classification:

F23B 80/02
F24H 3/12

US Classification:

110207, 126117

Abstract:

A furnace system including a combustion vessel having an outlet end and at least one aperture extending into an interior area defined by the combustion vessel. The furnace system includes a flue duct coupled to the outlet end and in fluid communication with the interior area. A recirculation duct extends from the flue duct to one or more of the apertures and provides fluid communication between the flue duct and the interior area

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.

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.

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.

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.
