摘要： This valve is integrated into a fluid distribution network and enables selective interruption or authorization of the circulation of a fluid. The valve includes a fluid blocking member driven in rotation by an actuator device of the valve and at least one journal, a hollow body inside which the blocking member is mobile and which defines at least one bore for receiving the journal, and a bearing disposed around each journal and inside the bore of the body enabling support of the journal and guidance thereof in rotation relative to the bore, thereby centering the journal. The valve further includes a device for immobilizing and sealing for maintenance the journal relative to the body of the valve. This immobilization device is disposed on the same side of the bearing as the internal volume of the hollow body and is maneuverable via the bearing to go from a non-clamped first configuration to a clamped second configuration in which it immobilizes the journal in the bore and vice versa.

摘要： The invention refers to a forced flow steam generator (10) and to a method for its operation. The forced flow steam generator (10) has a combustion chamber (11) with a burner arrangement (20). A fuel (B) and a mixture (G) consisting of pure oxygen and flue gas (R) are fed into the combustion chamber (11) or to the burner arrangement (20) for combusting. A flue gas duct (27) is connected to the combustion chamber (11) in the flow direction (S) of the flue gas (R), and a flue gas passage (26) is connected to the flue gas duct. The flue gas (R) for the oxygen-flue gas mixture (G) is fed back from the flue gas passage (26) via a flue gas recirculation line (28). The forced flow steam generator (10) is operated in the so-called oxyfuel process. A plurality of auxiliary heating surfaces (35) are arranged in the flue gas duct (27) downstream of the burner arrangement (20). Between the burner arrangement (20) and the auxiliary heating surfaces (35), provision is made for a wall heating surface arrangement (36) which at least partially covers a combustion chamber wall section (38) of the combustion chamber wall (12) which delimits the combustion chamber (11). For this purpose, the wall heating surface arrangement (36) has a plurality of wall heating surfaces (37) which butt against the respectively associated segment of the combustion chamber wall section (38). The operating medium (A) flows through the wall heating surface arrangement (36) and in this way thermal energy is dissipated from the flue gas (R) in order to limit the heating of the operating medium (A) in the combustion chamber wall tubes (13) and therefore to limit wall tube temperatures in the upper section of the boiler.

摘要： A method for operating a steam power plant at low load is suggested comprising the extraction of live steam LS before the last superheater SH3 and/or resuperheated steam before the last resuperheater RSH2 and using the thermal energy of this steam in other heat sinks. Thus, nearly constant steam parameters of the live steam LS are achieved and the overall efficiency of the steam power plant remains at a high level.

摘要： A fuel cell system comprises a fuel cell main body containing a fuel cell having an anode side at which fuel is reacted, exhaust products arising at the anode side of the fuel cell as a result of the reaction at the anode side. A recirculation passage is located inside the fuel cell main body and recirculates a proportion of the exhaust products directly to the anode side of the fuel cell for reaction at the anode side. The recirculation passage may include an ejector arrangement for mixing fresh fuel with the recirculated exhaust products and may also include a reforming catalyst for partially reforming the mixture in the recirculation passage.
