    Another oxygen generator is the OBA, oxygen breathing apparatus, used to fight fires along with the FFE, firefighter ensemble. They are also sodium chlorate candles, but on a smaller and more mobile design. Last an hour but for safety reasons timers are set to 30 minutes to allow the canisters to be swapped out.

    The preheating process is likely to streamline the process so the amount of time it takes to scrub the CO2 is reduced in the primary boiler scrubber. Think of it like boiling hot water vs. starting with cold water. I could be wrong but that could be one reason.

    One thing that has always had me wondering is how do they replenish the "nitrogen" in the atmosphere of the ship? Sure, you can make oxygen by electrolysis and scrub out some of the carbon dioxide but nitrogen is the biggest fraction of our atmosphere at around 78%. You can't stay down constantly and just replenish oxygen. I assume there is some outgassing somewhere in the system and the nitrogen content would go down and the oxygen content would go up until you have flash-fires. You would also build up some other more rare components of the metabolic processes of people (methane, ethane and a dozen or so others that I have forgotten). Periodically you need to snorkel and do an air exchange to purge those out.

    I like Destin's channel, but the submarine thing I can't really appreciate, as to me it keeps showing us how much money we're willing to invest in warfare and armaments as opposed to making the world better (I do realize some may say that it would be far worse if the"good guys" wouldn't defend us from the"bad guys", but that again demonstrates the stupidity of mankind)

    Forgive my ignorance, i'm normally quite astute. For one, i understand a nuclear sub can work below as long as the food lasts. These candles are new to me, and they are burned at regular intervals, my question is, how many do they go to sea with, and how are they stored? Food storage/candle storage, what is the ratio. Did i miss something? It seems these are essential, as is food.

    A clinker is an artificial stone created by some chemical process. Initailly used for bricks, later for the material ground into cement. Makes sense here. But why is the chemical reaction regarded safer than having pressurized oxygen on board? Yes, and for long-term use, the MEA cycle is better than the LiOH cannisters.

    I bet those oxygen candles contain the same thing as the emergency oxygen generators on aircraft, just on a much larger scale (the aircraft ones run for about 9-12 minutes, enough time for the pilot to get down to an altitude where the oxygen concentration is high enough that supllemental oxygen is no longer needed). It still defies logic when you hear the officer say "were going to make oxygen by burning this candle". In this case chemistry > logic ;)
