摘要： A method of operating an oxycombustion circulating fluidized bed (CFB) boiler that includes a furnace having a grid at its bottom section, a solid material separator connected to an upper part of the furnace, and an external solid material handling system. Oxidant gas is introduced into the CFB boiler through the grid as fluidizing gas, the fluidizing gas including recirculating flue gas. Fuel material is introduced into the circulating fluidized bed. A sulfur reducing agent including CaCO3 is introduced into the circulating fluidized bed. Solid material is circulated out of the furnace and provides an external circulation of solid material via the external solid material handling system. The solid material is fluidized in the external solid material handling system by introducing a fluidizing medium including recirculating flue gas into the handling system. A predetermined amount of steam is introduced into the handling system as a component of the fluidizing medium.

摘要： A gasification furnace (110) of a circulation fluidized bed-type gasification furnace (100) forms a fluid medium into a fluid bed, and produces gasified gas by gasifying an input gasification raw material using heat from the fluid medium. A combustion furnace (102) heats the fluid medium output from the gasification furnace. A flow rate adjuster (106) distributes the fluid medium heated in the combustion furnace to the gasification furnace and a buffer section (112). In this manner, irrespective of the flow rate of the fluid medium in the entire circulation fluidized bed-type gasification furnace (100), the buffer section (112) enables the fluid medium to bypass to the combustion furnace. As a result, the flow rate of the fluid medium in the gasification furnace (110) can be maintained at a desired flow rate.

摘要： Exemplary chemical looping systems include at least one type of active solid particles and inert solid particles that may be provided between various reactors in exemplary systems. Certain chemical looping systems may include a reducer reactor in fluid communication with a combustor reactor. Some chemical looping systems may additionally include an oxidizer reactor in fluid communication with the combustor reactor and the reducer reactor. Generally, active solid particles are capable of cycling between a reduction reaction and an oxidation reaction. Generally, inert solid particles are not reactants in either the reduction reaction or the oxidation reaction.

摘要： A chemical looping combustion (CLC) based power generation, particularly using liquid fuel, ensures substantially complete fuel combustion and provides electrical efficiency without exposing metal oxide based oxygen carrier to high temperature redox process. An integrated fuel gasification (reforming)-CLC-followed by power generation model is provided involving (i) a gasification island, (ii) CLC island, (iii) heat recovery unit, and (iv) power generation system. To improve electrical efficiency, a fraction of the gasified fuel may be directly fed, or bypass the CLC, to a combustor upstream of one or more gas turbines. This splitting approach ensures higher temperature (efficiency) in the gas turbine inlet. The inert mass ratio, air flow rate to the oxidation reactor, and pressure of the system may be tailored to affect the performance of the integrated CLC system and process.

摘要： The invention relates to a plant and to a method for chemical looping oxidation-reduction combustion of a gaseous hydrocarbon feed, for example natural gas essentially containing methane. According to the invention, catalytic pre-reforming of the feed is performed in a pre-reforming zone comprising a fixed reforming catalyst, while benefiting from a heat transfer between the reduction or oxidation zone of the chemical loop and the pre-reforming zone adjoining the reduction or oxidation zone. Pre-reforming zone (130) and oxidation zone (110) or pre-reforming zone (130) and reduction zone (120) are thus thermally integrated within the same reactor (100) while being separated by at least one thermally conductive separation wall (140).
