Question:
Our school is considering switching from propane to natural gas in our science department. What is the flame temperature of propane versus natural gas?


Replies:
Smaranda,

If you burn a sufficient amount of each with the proper amount of oxygen, both gases will produce a flame that is sufficiently hot for lab use. However, mole for mole, propane is a more energetic fuel than methane (natural gas) because, of the two, propane molecules are larger. Most Bunsen burners used in science labs are designed to be used with natural gas. Assuming your lab is equipped with burners set up for propane, the orifice in your lab burners will likely have to be changed because those for propane are smaller than those to be used with methane.
