Abstract: Sulfur dioxide (SO2) is removed from carbon dioxide feed gas comprising SO2 as a contaminant by maintaining the carbon dioxide feed gas at an elevated pressure in contact with an alkaline sorbent for a period of time sufficient to react said alkaline sorbent with SO2. Where NOx, oxygen (O2) and water are also present, not only is the rate of reaction with the sorbent increased, but also additional SO2 is removed by conversion to sulfuric acid, and NOx is removed as nitric acid. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a hydrocarbon or carbonaceous fuel.

Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.

Abstract: Sulfur dioxide (SO2) may be removed from carbon dioxide feed gas by contacting the carbon dioxide at an elevated temperature and an elevated pressure with a catalyst for oxidizing SO2, in the presence of oxygen (O2) to convert SO2 to sulfur trioxide (SO3); contacting SO3 in the resultant SO3-enriched carbon dioxide gas with water to produce sulfuric acid and SO2-depleted carbon dioxide gas; and separating the sulfuric acid from the SO2-depleted carbon dioxide gas. If present, NOx is also removed from the carbon dioxide feed gas as nitric acid to produce SO2-depleted, NOx-lean carbon dioxide gas. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a hydrocarbon fuel or carbonaceous fuel, within or downstream of the CO2 compression train of a CO2 recovery and purification system.

Abstract: Carbon monoxide (CO) may be removed from flue gas generated by oxyfuel combustion of a hydrocarbon or carbonaceous fuel, by contacting the flue gas, or a CO-containing gas derived therefrom, at a first elevated temperature, e.g. at least 80° C., and at a first elevated pressure, e.g. at least 2 bar (0.2 MPa), with at least one catalyst bed comprising a CO-oxidation catalyst in the presence of oxygen (O2) to convert CO to carbon dioxide and produce carbon dioxide-enriched gas. The carbon dioxide produced from the CO may be recovered from the carbon dioxide-enriched gas using conventional carbon dioxide recovery techniques. NO in the flue gas may also be oxidized to nitrogen dioxide (NO2) and removed using conventional NO2 removal techniques, or may be reduced in the presence of a reducing gas to nitrogen (N2) which does not have to be removed from the gas.

Abstract: A superheater in a power plant that superheats steam to operation conditions exceeding an operating limit of an associated steam-producing boiler. The superheater combusts oxygen and fuel with cooled recycled combustion gas to produce a CO2-rich combustion product gas stream at a fixed temperature. The combustion gas is used as the heat transfer fluid in the superheater's heat exchanger. The CO2-rich flue gas stream allows for efficient capture of substantially pure CO2. The superheater may be retrofitted to an existing power plant as a separate component, external to the boiler. The plant may thus have its electrical power output increased, while its overall CO2 emissions per nit of generated power is decreased, even when inexpensive, readily-available fossil fuels are used as the primary fuel for filing the boiler and/or the superheater.

Abstract: A locking plate fast fastening ceiling fan blades includes a clamp plate. A first chute is on the clamp plate, where a pushing board is contained. A thru hole and a position limiting unit are provided in the first chute of clamp plate. A wedge unit is provided on the pushing board. When a set of blades is installed on a blade rack of a ceiling fan, only the blade is set around several pillars on the blade rack, the clamp plate of locking plate is set to locate on the pillar, and a pillar passes through the thru hole. The pushing board of locking plate is shifted toward the pillar to make the front end of pushing board stay close to the side of pillar and make the wedge unit wedge to the position limiting of clap plate for fast and exactly fixing the blade onto the blade rack.

Abstract: The present invention uses a DNA-based biopolymer material as a host for phosphor guest materials that are used for solid state lighting. The DNA-biopolymer replaces the epoxies, which are typically used as the hosts for these phosphors. The resulting DNA-biopolymer phosphor can either be deposited directly on the light emitting diode die by casting or onto the inside of the lens or dome placed on top of the LED by casting, spin depositing, electro-spinning or vapor deposition. The purpose of the invention is to enhance the light output and efficiency of solid state lighting and to red shift the light emission or shift the emission to longer wavelength. This would render brighter solid state lighting that operates at lower input power, generate less heat and have longer lifetimes. It would also reduce or eliminate the cold or blue tinted color of solid state lighting by warming or red shifting the emission of these devices.
