摘要： A device for trapping flammable gases such as hydrogen comprises active means (3) inside a casing (1) which is closed except for openings which are plugged by filters (2) that normally allow only the gases that are to be trapped to pass through them. The trapping maintains a reduced pressure inside the casing, which continually draws in the gases produced outside. The trap can operate without any maintenance and for long periods of time, even in a completely enclosed environment.

摘要： A hydrogen venting device for separating and releasing hydrogen gas from a gaseous mixture comprising hydrogen and steam generated in nuclear power plants is disclosed. The method includes providing a chamber at a high point in the cooling water circuit, allowing the collection chamber to cool below a gaseous mixture inlet temperature thereby allowing the hydrogen to collect at a first elevation within the collection chamber and condensate of the steam to collect at a second elevation within the collection chamber below the first elevation, and releasing substantially only hydrogen from the collection chamber at or proximal the first elevation when a threshold temperature, less than the first temperature, is reached.

摘要： A hydrogen treatment facility for treating hydrogen without using a power source is disposed outside a reactor containment vessel and in an upper portion of a reactor building. A hydrogen detector detecting hydrogen in the reactor building is connected to a control apparatus operated by an independent power source activated at the time of a station black-out. A circulation passage for air circulation generated in the reactor building is disposed in the reactor building and outside the reactor containment vessel. A hydrogen treatment duct connects to the circulation passage and a gangway and a room with equipment. During a severe accident and station black-out and when hydrogen concentration detected by the hydrogen detection apparatus exceeds a set concentration, the hydrogen treatment duct is put in use by the control apparatus. Air containing the hydrogen is introduced into the hydrogen treatment facilities through the hydrogen treatment duct and the circulation passage.

摘要： Example embodiments relate to methods of controlling hydrogen concentrations in an offgas system of a nuclear reactor by passive air injection. A method according to a non-limiting embodiment may include passively injecting ambient air through the hydrogen water chemistry system into an existing offgas line of the offgas system. The offgas line is configured to transport non-condensable gases, including hydrogen, from a condenser to a recombiner. As a result of the passive air injection, the combined flow of hydrogen and oxygen react in the recombiner to form water vapor, thereby reducing the hydrogen concentration of the offgas exiting the recombiner.

摘要： An apparatus for removing flammable gas is started only when a concentration change in the flammable gas in a primary containment vessel is detected, so that the decrease in activity of a catalyst due to a catalyst poison is prevented. This apparatus has a catalytic recombining apparatus equipped with a catalyst 1 for reacting the flammable gas, a case 2 that houses the catalyst, and lids 4a and 4b installed at openings 3a and 3b of the case 2. Adhesive parts 5a and 5b which adhere the lids 4a and 4b and the case 2 is melted at high temperatures, and heating elements 6a and 6b composed of an oxidizing catalyst of hydrogen is installed in contact with the adhesive parts 5a and 5b. Thus, the lids are not only closed under normal conditions but opened when the adhesive parts 5a and 5b being melted along with the temperature increase in the surrounding atmosphere.

摘要： An ignition system has a plurality of spark igniters for the recombination of hydrogen in a gas mixture. The ignition system provides and ensures reliable early ignition of an ignitable gas mixture, even in the case of comparatively fast gas displacement. Each spark igniter is, according to the invention, configured as a high-speed igniter with an operating frequency in excess of about 10 Hz. In order to ensure reliable ignition of the ignitable gas mixture both in the event of a temporary failure of external units, and when the ignition system has a particularly long operating time, the spark igniters are advantageously connected together in groups for supplying them with energy. Each group of spark igniters is connected to an intermediate energy store common to them, and the intermediate energy stores are connected to a central energy supply unit.

摘要： An igniter apparatus which generates a high speed buoyancy induced vortex to funnel hydrogen and air from the surrounding onto the “igniter core” where an “igniter core” heats up to the auto ignition temperature by the exothermic catalytic oxidation of hydrogen on its surface. Water (vapor) is formed as the product, which inhibits the oxidation reaction, if not stripped away from the catalyst surface. The high velocity of the vortex ensures the stripping of the boundary layer of steam that is formed by the reaction, thus ensuring more active sites are available for hydrogen oxidation. The vortex is formed by channeling an upward draft into a vortex by guided fins. The upward draft is formed by a plate, which is also coated with a hydrogen recombination catalyst. The plate becomes hot by the same catalytic oxidation reaction in the presence of air containing hydrogen.
