Applications of Fuel Gas

Applications of Fuel Gas

Fuel gases have many practical applications in industrial settings. This specialized type of gas produces heat energy that is transmitted to perform specific functions. 

Most fuel gases are comprised of combustible hydrogen, carbon monoxide, and hydrocarbons like methane or propane, and oil vapors. It can also be a mixture of those gases.

Let’s take a look at how it’s used across different industries.

Applications of Fuel Gas

From transportation, to welding and cutting, to heating, fuel gas is vital for a variety of applications. 


Fuel gas powers transportation, from cars to motorcycles, trucks, boats, and airplanes. The fuel gas is mixed with air to create a vaporous substance that will compress and explode. The force from the explosion propels the pistons and gets vehicles moving. 


In welding, the fuel gas acetylene is used. It is mixed with oxygen to reach a high enough temperature that can melt metal. 


When cutting metals, propane is heated by a flame until it reaches the right temperature for ignition. A jet of pure oxygen will then be directed towards a heated surface so the metal burns with oxide debris from the cut.  

General Heating

Propane is also used for general heating. For brazing and soldering, other fuel gases can be used since they don’t need exceedingly high flame temperatures. 

Fuel gases are also used in burners, heaters, and camping stoves. 

Fuel Gases by nexAir

Do you need specialized fuel gases for your operations? nexAir supplies a wide range of fuel gases to help you Forge Forward and achieve success. Our gases can be made to suit many applications. Here are some of nexAir’s fuel gases:

Acetylene (C2H2)

Acetylene is a colorless gas and hydrocarbon. It is lighter than atmospheric air but is one of the hottest and most efficient fuel gases. It’s used in many industries and is often involved in heating processes. 

Hydrogen (H2)

Hydrogen is an odorless, colorless, tasteless, non-toxic, yet highly combustible gas. It is abundant in the environment, representing around 75% of normal matter. Hydrogen is the only fuel gas without carbon and offers the highest thermal conductivity among all gases. It’s ideal for many industrial activities. 

Propane (C3H8)

Propane is a colorless and highly flammable liquified gas at standard temperature and pressure. It is obtained by processing and refining natural gas. Propane is heavier than air and is one of the key components of liquid petroleum gas. 

Alternative Fuel Gases

nexAir also carries the following:


Starflame is a cutting fuel that burns hotter than other fuel gases, making it more economical and environment friendly. 

Propylene (C3H6)

Propylene is a colorless, flammable, liquified gas with a distinct odor. It burns hotter than propane but offers better safety as it can withstand full-tank pressure. 

Other Gases

nexAir also carries the following gases:

  • Anhydrous Ammonia
  • Argon
