Likely not.
On first thought, it appears to make sense, because pure nitrogen is not flammable and thus reduces the risk of the hot flame igniting the balloons fabric hull.
But this is not easily feasible, because the flame, if directly heating the balloon filling, needs the airs oxygen content to burn completely.
You could use a premixed-flame burner that mixes air and a combustible gas prior to entering the combustion zone and heating the balloon filling gas. But still, this would require a gas tight balloon hull. And that is not desired in a hot-air type balloon, because thermal expansion and contraction of the balloon gas (air) during each burn/burn-pause cycle causes enormous differences in gas volume and requires a means of pressure-relief (i.e. an opening).
Improved Answer.
Interesting theories but the brief answer is that nitrogen is not used in hot air balloons, although it is sometimes used when it is extremely cold to boost the pressure in the fuel tanks, since the power output of the burners is dependent on the pressure. The burners draw liquid propane so the nitrogen is not drawn into the flame
What else can I help you with?
Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
Is a hot air balloon filled with helium?
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
How were hot air balloons used when first invented?
When hot air balloons were first invented, they were mainly used for recreational purposes and entertainment. They were also used for scientific experiments, such as studying the atmosphere and meteorology. Additionally, military forces used hot air balloons for reconnaissance during wars.
What are hot air balloons used for now a days?
Hot air balloons are now mostly used for leisure
Is helium used in hot air balloons?
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
How were hot air balloons used by the military?
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Which gas do you use for hot air balloons?
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
Why is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
How were hot air balloons used during World War 1?
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.
What source is used to fly hot air balloons?
Wind !... The balloons are filled with hot air, which causes them to rise. They are then at the mercy f the wind direction.
Is a hot air balloon filled with helium?
No, hot air balloons are typically filled with hot air to become buoyant and rise. Helium is an alternative gas used in some balloons, like party balloons or weather balloons, due to its lighter weight than air.
What gas do hot air balloons contain?
Hot air balloons are typically filled with heated air, which is lighter than the surrounding air and provides lift. Some balloons may also use helium or hydrogen gas for buoyancy, but hot air is the most commonly used lifting gas for traditional hot air balloons.
Which gas is in hot air balloons?
Mostly nitrogen, since a hot air balloon uses air & air is mostly nitrogen.Let your ears hear what your lips are saying !The hot-air balloon rises because it is inflated with . . . . . . . . wait for it . . . . . . . . hot air !
