摘要： An apparatus (1) for generating oxygen has a reduction reactor (2) fluidly connected to and located at least partially within an oxidation reactor (3), where oxygen-carrier particles (4a, 4b) are transferred between the reduction and oxidation reactors. An outlet conduit (5) transfers an oxygen-enriched mixture from the reduction reactor to an oxygen storage unit (6). A corresponding method provides a chemical looping process using oxygen-carrier particles transferred between reduction and oxidation processes, where oxygen-depleted carrier particles produced in the reduction process are transferred to and regenerated in the oxidation process. Oxygen is separated from an exhaust gas mixture produced in the reduction process. The reduction process is carried out at a higher temperature than the oxidation process. A system (20) uses the apparatus and a condenser (22) for condensing the oxygen-enriched mixture from the outlet conduit (6).

摘要： Various aspects provide for a fluidized bed reactor comprising a container having a bed of bed solids and a splashgenerator configured to impart a directed momentum to a portion of the bed solids. A wall may separate the bed solids into first and second reaction zones, and the directed momentum may be used to transfer bed solids from one zone to the other. A return passage may provide for return of the transferred bed solids, providing for circulation between the zones. A compact circulating bubbling fluidized bed may be integrated with a reactor having first and second stages, each with its own fluidization gas and ambient.

摘要： A nozzle for a circulating fluidized bed (CFB) boiler of the present disclosure relates to the field of mechanical engineering. The nozzle creates resistance to ingress of fine solid particles and maintains uniform air distribution therethrough. The nozzle has a body having a predetermined thickness and at least one passage configured along the thickness of the body such that, the passage extends from an inner surface of the body and terminates at an outer surface of the body. The passage facilitates the flow of a fluid from a lumen formed within the body to the outer surface of the body and vice versa. The passage has at least one bend. The bend restricts the backflow of fine solid particles through the nozzle to avoid the disturbance to the air flow pattern by the fine solid particles within the windbox.
