摘要： Provided is a boiler plant including a carbon dioxide capture system. The carbon dioxide capture system has an absorbing-liquid regeneration device and an absorber. The absorbing-liquid regeneration device includes a regenerator, a first circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, and a second circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, a heat exchanger, a heater, and a switcher. The heat exchanger heats the absorbing liquid by exchanging heat between the absorbing liquid flowing through the first circulation line and steam from the boiler. The heater heats the absorbing liquid flowing in the second circulation line. The switcher switches between a first heating state in which the absorbing liquid flows in the first circulation line and a second heating state in which the absorbing liquid flows in the second circulation line.

摘要： The invention comprises: a) first comburent supplying means (18) connected to the lower part of the oxidation chamber, for introducing pressurized oxygenated gas in the oxidation chamber at a speed that comprises a tangential component; b) a particle recirculation system, which comprises: a particle separator (24) on the upper part of the oxidation chamber for trapping hot particles of ash and unburned material, and a transportation system (25) for transferring trapped particles from the particle separator (24) to the base of the oxidation chamber; and c) a gas recirculation system comprising: a sucker (26) for suctioning combustion gases from the upper part of the oxidation chamber, and pipes (27) for transferring the suctioned gases to the base of the oxidation chamber. It provides an optimized thermal transfer that reduces the emission of pollutants in waste recovery.

摘要： The inventive technology includes methods and apparatus for the generation and application of segregated catalytic additives for the pre-combustion treatment of carbonaceous fuel and/or feedstocks. The application of such segregated additives results in the reduction of environmentally harmful emissions during combustion as well as gasification processes. Specifically, pre-combustion treatment of carbonaceous materials with the inventive additives results in the reduction of NOx and/or mercury emissions by least 20% and 40% respectively.

摘要： The Smoke Chamber Sealing Device is a non-solely-cement method and system of sealing Smoke Chambers. Material such as metal, plastic, glass, composite, and/or any other material suitable for smoke chambers can be formed into the layers that seal smoke from going to where it is not supposed to go. One of many designs can involve installing metal walls on the inner walls of a smoke chamber, these metal walls would last much longer than cement and would be easier to work with considering the difficulties of parging a smoke chamber.

摘要： A cooling system is configured to cool exhaust gases exiting a furnace of a steel production system through an exhaust hood, a dropout box, and a hot gas duct of the steel production system. The cooling system includes an inlet configured to receive water from a water pump for cooling the exhaust gases, and an outlet configured to exhaust the water from the cooling system. The cooling system further includes a first water line configured to supply the water to the exhaust hood of the steel production system for cooling the exhaust gas received therein, and a second water line configured to supply the water to the dropout box of the steel production system for cooling the exhaust gas received therein. The cooling system also includes a third water line configured to supply the water to the hot gas duct of the steel production system for cooling the exhaust gas received therein, and each of the first water line, the second water line, and the third water line are operably coupled between the inlet and the outlet of the cooling system. The cooling system also includes a controller configured to control and maintain a defined temperature of the water circulating within the cooling system.

摘要： A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000° C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; the classifying step that introduces the heat-treated fly ash containing the unburned carbon in decreased amounts obtained through the heating step into a classifying apparatus in the state of being heated at a high temperature so as to separate the fly ash into a coarse powder and a fine powder; the fine powder recovering step that recovers the fine powder of the heat-treated fly ash obtained through the classifying step by using a dust-collecting apparatus; and the milling step that mills the coarse powder of the heat-treated fly ash obtained through the classifying step until a 45 μm sieve residue becomes not more than 34% by mass, and then recovers the milled powder.

摘要： A method is provided for producing carbon dioxide by combusting a carbonaceous fuel with oxygen or with a gas mixture containing more than 25 mol % of oxygen obtaining a flue gas mixture, wherein the flue gas mixture is processed obtaining a secondary gas mixture containing carbon dioxide and oxygen, and wherein a part of the oxygen contained in the secondary gas mixture is catalytically reacted with a first auxiliary fuel in a reactor system comprising a series of multiple reactors, obtaining further carbon dioxide and water. A further part of the oxygen contained in the secondary gas mixture is catalytically reacted with a second auxiliary fuel in the reactor system. A corresponding apparatus is also described herein.
