Translation of "Explosionsfähiges gemisch" in English

In certain concentrations may even occur a potentially explosive mixture.

Together with air, organic solvents may form an explosive mixture.

Fumes can combine with air to form an explosive mixture.

The diffuser at the same time forms part of the receiving space for an explosive mixture.

The gas to be added should be oxygen-free to prevent it from forming, together with hydrogen, an explosive mixture.

The term dust cloud describes dust particles that along with air form a potentially explosive mixture.

During the loading process, an explosive mixture of dust and air may occasionally form in the area where the drum is emptied into the loading hopper.

While the dust was being loaded into the mixer, an explosive mixture of solvent vapour and air was formed, and was ignited by electrostatic sparking generated during the filling process.

The vapour of 1,3,5-Triethylbenzene can form an explosive mixture with air (flash point: 76 °C).

Therefore, should an explosive mixture be ignited when a explosion-proof housing 6 is placed on the bus bar duct 1, a breakdown is prevented because the plug connection has already formed a explosion-proof enclosure with a protective gap, and a separation of this plug connection or an opening of the explosion-proof space of the connector is made impossible by the mechanical connection which is already established by the screws 15.

The sequence of the individual steps is to be selected such that at no time in the process can an explosive mixture form in the apparatus, and that, if some components fail, the development of a safety hazard can reliably be prevented. SUMMARY OF THE INVENTION

This constitutes a major safety hazard since the hydrogen gas can form an explosive mixture with the ambient atmosphere, which can easily be ignited by the sources of ignition commonly found in wind turbines.

Since ammonia and nitrous oxide form an explosive mixture, the aforedescribed mode of operation for producing sodium azide has given rise to explosions in case the two gases are in an explosive mixing range.

Otherwise there is a danger of an explosive mixture of air and cleaning agent igniting when switching the instrument on.

This ensures that, even in the event of a simultaneous leak on the anode side and the cathode side of the fuel cell module, it is impossible for an explosive mixture to enter the pressure vessel.

Redox devices having at least one redox unit configured as fuel cell or electrolyzer according to the prior art are flushed with an inert flushing gas, usually nitrogen, after a shutdown in order to prevent residual amounts of gases used, e.g. hydrogen and oxygen, which remain in gas spaces of the redox unit after shutdown, from coming into contact with one another by diffusion and from being induced to form an explosive mixture, for example a hydrogen/oxygen gas mixture, in the redox unit, said mixture being induceable to explode due to energy input, in particular when the redox unit is started up once again, as a result of which the redox unit can be damaged.

The cleaning apparatus, towards the cleaning-side end section can include an outlet device with an additional receiving space for an explosive, gaseous mixture.

This scavenging air can thereby flush out any slight leakages of hydrogen and/or oxygen from the housing and feed these to an area of the fuel cell system in which either adequate dilution takes place so that an explodable mixture no longer exists, or in which the hydrogen is combusted or catalytically combusted in order to thus avoid hydrogen emissions and ignitable mixtures.

At the same time, an adequate volumetric flow of primary air must flow into the undergrate chamber so that, on the one hand, the grate is cooled and, on the other hand, the risk of combustible gases diffusing back from the combustion space into the undergrate chamber at a primary-air volumetric flow which is too low is removed, these gases forming an explosive mixture with the added oxygen in the undergrate chamber.

Over and above the problem of coking, after the shutdown of a gas turbine operated with liquid fuel there is also the risk of the fuel passing from the fuel systems in an uncontrolled fashion into the combustion chamber when the rotor is stationary, or into the boiler possibly connected downstream of the gas turbine and forming an explosive mixture there with air at rest.

The cleaning method according to the present invention is based on bringing an explosive mixture into the proximity of a location to be cleaned, in order to subsequently bring to mixture to explode.

A gaseous, explosive mixture can be produced afresh in the receiving space subsequently to the explosion, by way of renewed opening of the at least one metering fitting.

The gaseous components as a result of this are led as an explosive mixture through the feed pressure channel of the feed pressure conduit, which connects onto both introduction channels, to the cleaning-side end section.

The place of installation is such an environment and/or pipeline, in which an explosive gas/vapour - air mixture may be formed.

Roughly 80% of all dust that accrues during industrial manufacturing is combustible and can, if a potentially explosive dust-air mixture is present, lead to an explosion.

This is because the charge can reach such high energy levels that sparks can develop, for example, when the hose line is connected, and these sparks can ignite an explosive mixture.
