You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion. When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
What does it mean when a flame burns blue?
A blue flame colour means complete combustion. This indicates that the gas is being burned efficiently without any unburned and wasted gas.

What does a green flame mean in a fire?
A green flame, for instance, indicates the presence of copper. As copper heats up, it absorbs energy that’s manifested in the form of a green flame. A pink flame, on the other hand, indicates the presence of lithium chloride. And burning strontium chloride will create a red flame.
Why is blue fire the hottest?
Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.

How do I know if my gas fire is leaking carbon monoxide?
- You see black, sooty marks on the front covers of gas fires.
- There is heavy condensation built up at the windowpane where the appliance is installed.
- Sooty or yellow/brown stains on or around boilers, stoves, or fires.
- Smoke building up in rooms.
Is blue flame better than yellow?
Combustion is incomplete and less energy is transferred. A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. … This is because a yellow flame produces a lot of soot. Carbon monoxide, soot and water vapour are produced as well as carbon dioxide.
Are blue flames toxic?

What causes purple flame?
