Under the optimal combustion condition (a 29% hydrogen … WebNov 10, 2024 · Make sure that the final hydrogen-to-air ratio is between 8-12%, The default gas flows for an FID are: 30 ml/min for hydrogen/fuel . 25 ml/min for makeup (check that the correct makeup gas is configured) 400 ml/min for air/oxidizer. If required, these flow rates can be adjusted (in some cases, you need a higher hydrogen flow to get ignition).
WebNov 22, 2024 · Hydrogen is less dense than oxygen so it should rise to the top of the container, though you would not be able to see it. With this in mind, theoretically if you used a bottle rather than a cup and had a small tube to run the hydrogen off with you could potentially store the hydrogen separately. WebMar 8, 2013 · They measured the pressure developed in various gas mixtures, the greatest pressure of 7.6 atm being developed for a stoichiometric mixture of hydrogen and oxygen. The flammability limits of hydrogen in air are very wide, from 4% to 75%, and the detonation limits narrower, from 18.3% to 59% at atmospheric pressure.
WebApr 29, 2013 · Hydrogen is quick to burn in the presence of oxygen (O2) and can be very explosive. Used as the primary fuel for combustion when launching space shuttles, this is seriously powerful stuff. When …
