Abstract: The invention relates to a security device forming a pressurized gas release valve, said device including a body that defines a gas flow channel extending between a first upstream end, to be placed in contact with a source of pressurized gas, and a second downstream end, to be placed in contact with the outer atmosphere, the device including a stopper that is located on the channel so as to prevent the flow of the gas between the upstream end and the downstream end in a normal situation, the stopper being fusible and/or frangible so as to release the gas passage in the event of a dangerous situation when a pressure and/or a temperature exceeds a predetermined threshold. Said device is characterized in that said device includes a tank of an unstable, exothermically decomposable gas that is placed in communication with the pressurized gas released during the melting/breaking of the stopper.

Abstract: The invention relates to a method for the deoxygenation in a chemical loop of smokes resulting from oxidation-combustion reactions, that comprises: a first step during which the smokes are stripped from their oxygen by trapping the same by the oxidation of an oxygen-carrier material, thus producing a main flow of smokes with a reduced oxygen content; and a second step for also producing smokes that can join the main smoke flow and during which the material oxidized during the first step is reduced and regenerated by reaction with the fuel in order to be used again during said step. The invention also relates to an apparatus for implementing said method.

Abstract: The invention relates to a method for producing power from at least one fuel, said method including: a step of oxidizing said fuel by means of placing it in contact with at least one oxygen loaded solid compound and of concomitantly reducing said solid compound.
