How do nuclear submarines get air?

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction.

How does air circulate in a submarine?

The ventilation system circulates cooled, heated and dehumidified air throughout all compartments of a submarine. Electrostatic precipitators remove dust and smoker and other particles. Main induction fans circulate the air (heated or cooled by the ocean).

How does a nuclear submarine work?

Reactors in a nuclear-powered submarine are typically fuelled with uranium. In turn, more neutrons are released and the process continues in a so-called “nuclear chain reaction.” The energy is given off as heat, which can be used to drive turbines that generate electricity for the submarine.

How do submarines replenish compressed air?

It is true that air is released from the ballast tanks and water is let into them through special valves to enable a submarine to dive, but the sub does not get air back to surface again. It carries down tanks of compressed air that can be used to empty the ballast tanks of water.

How does a submarine create oxygen?

Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails. Waste CO2 is released into the sea whenever it’s possible.

How do submarines not run out of air?

Submarines don’t run out of air, they take seawater, distill it and then run that through a machine the zaps the water with electricity to separate oxygen and hydrogen atoms. They pump they explosive hydrogen gas out to sea and run the oxygen through a compressor and store in in huge tanks.

How do submarines ventilate?

Breathing space. Ventilation is obviously a vital consideration in any submarine. When submerged, the air in the submarine is continuously recirculated using centralised fans with electrostatic precipitators to filter out particulates and aerosols, and chilled-water coils to cool and remove excess moisture.

How do submarines get breathable air?

How does the crew get breathable air inside a submarine? Oxygen onboard a submarine is released either through compressed tanks, an oxygen generator, or by some form of an ‘oxygen canister’ that works by electrolysis.

How does nuclear power work on a submarine?

Nuclear submarines and aircraft carriers are powered by onboard nuclear reactors. Atoms in the nuclear reactor split, which releases energy as heat. This heat is used to create high-pressured steam. The steam turns propulsion turbines that provide the power to turn the propeller.

What is the percentage of carbon dioxide in air in a submarine?

Exhaled air contains about 4.5 percent carbon dioxide. Our bodies do not do anything with nitrogen or argon. A submarine is a sealed container that contains people and a limited supply of air. There are three things that must happen in order to keep air in a submarine breathable:

What is the difference between oxygen and water in a submarine?

Short answer: oxygen is supplied onboard a submarine through pressurized tanks or an oxygen generator, while drinking water is obtained by desalinating seawater. Interior of the tourist submarine Atlantis whilst submerged (Image Credit: Leonard G. / Wikimedia Commons)
