A method and a plant for capturing CO2 from an incoming flue gas. The flue gas can be exhaust gas from coal and gas fired power plants, cement factories or refineries. The incoming exhaust gas is cooled, mixed with air and compressed, and thereafter introduced into a combustion chamber together with gas and/or liquid fuel. Part of the combustion is achieved by separate burners with cooling/combustion air feed with a volume equal to the volume of CO2 captured. Said burners will elevate the temperature in the combustion chamber allowing combustion of exhaust gas with low oxygen content. CO2 is captured at high partial pressure before expansion by the gas turbine to produce power and generate steam in the heat recovery unit. The gas turbine will operate with high efficiency close to design parameters with respect to inlet temperature, pressure and flow.

Embodiments of the present disclosure are directed to systems and methods of removing carbon dioxide from a gaseous stream using magnesium hydroxide and then regenerating the magnesium hydroxide. In some embodiments, the systems and methods can further comprise using the waste heat from one or more gas streams to provide some or all of the heat needed to drive the reactions. In some embodiments, magnesium chloride is primarily in the form of magnesium chloride dihydrate and is fed to a decomposition reactor to generate magnesium hydroxychloride, which is in turn fed to a second decomposition reactor to generate magnesium hydroxide.

A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.

A method and device heat an object to be heated by a flame which is produced by supplying a fuel fluid and a combustion supporting gas to a burner as a heat, source. A temperature rising rate is increased by gradually increasing an oxygen concentration in the combustion supporting gas supplied to the burner and a device for heating an object to be heated including a burner for heating the object to be heated. A flow rate control unit controls a flow rate of a fuel fluid and a combustion supporting gas. A calculation unit transmits combustion information of the burner to the flow rate control unit, and the flow rate control unit increases a temperature rising rate of the object to be heated by increasing the oxygen concentration in the combustion supporting gas supplied to the burner.

The present invention relates to a high pressure process for Pre-Combustion and Post-Combustion CO.sub.2 capture (HP/MP/LP gasification) from a CO.sub.2 gas stream (CO2-Stream) by way of CO.sub.2 total subcritical condensation (CO2-CC), separation of liquid CO.sub.2, higher pressure elevation of obtained liquid CO.sub.2 via HP pump, superheating of CO.sub.2 up to high temperature for driving of a set of CO.sub.2 expander turbines for additional power generation (CO2-PG), EOR or sequestration (First new Thermodynamic Cycle). The obtained liquid CO.sub.2 above, will be pressurized at a higher pressure and blended with HP water obtaining high concentrated electrolyte, that is fed into HP low temperature electrochemical reactor (HPLTE-Syngas Generator) wherefrom the cathodic syngas and anodic oxygen will be performed. In particular the generated HP oxygen/syngas will be utilized for sequential combustion (“H.sub.2/O.sub.2-torches”) for super-efficient hydrogen based fossil power generation (Second new Thermodynamic Cycle).
