Why Does Propane Burn Blue?

Written on: June 26, 2023

A Blue Flame Lets You Know Your Propane Is Burning Safely and Efficiently.

fire flame colors Chatham county, nc People often ask why the flame is blue when they burn propane. After all, when you burn logs in a fireplace, the flames are usually red and yellow. While it might seem unusual, it’s actually a good thing. When you see a blue flame on your cooktop burners or the pilots for propane appliances, it means your propane is burning at maximum efficiency, and more importantly, safely.

Why Are Blue Flames Better?

When propane gas burns with the correct ratio of fuel to air, there is enough oxygen for complete combustion of propane. The gas molecules in the flame are ionized and the propane flame is blue—as it should be. The blue flame means that your propane is burning at its full heat so you aren’t wasting any fuel!

What Do Orange Flames Mean?

If you see orange or yellow flames on a propane burner, it’s a sign of a problem that can become a serious safety issue if you ignore it. It means the propane on those parts of the flame is not being completely burned. The incomplete combustion that causes these off-color flames can lead to a carbon monoxide buildup in your home—which can be deadly if not corrected promptly.

If you see orange flames on your cooktop, the cause is often simply spilled or burned food blocking parts of the burner on your range and causing incomplete combustion. If cleaning your cooktop doesn’t solve the issue—or the orange flames are in another appliance or a gas fireplace, contact us immediately.

In addition to potential for carbon monoxide buildup, orange flames mean that you’re only getting about half the heat from the flame. In complete combustion with a blue flame, the temperature of a propane flame is 3,596˚ Fahrenheit. With a yellow flame, the flame’s temperature is 1,832˚ Fahrenheit. When it comes to home heating or water heating, that drop in efficiency will show up in your bills. It will also affect your cooking—timing will be off, and you won’t get a good sear on that steak, or a nice crust on those hash browns.
