Liquefied Petroleum Gas (LPG) is widely used for cooking and heating purposes in many households around the world. With this, knowing what the color of the flame produced by an LPG burner is important, as it can indicate whether the burner is operating efficiently or if there might be a problem that needs attention.

1. Blue Flame
The ideal LPG flame color is blue. A steady, predominantly blue flame indicates that the gas is burning efficiently with the right air to fuel ratio. This results in complete combustion, where LPG is fully consumed without leaving soot or carbon monoxide. A clean blue flame means your burner is operating optimally and efficiently.

2. Yellow Flame
A yellow flame often indicates incomplete combustion. This occurs when there is not enough air mixing with the gas before ignition. Reasons for a yellow flame can include a clogged burner, incorrect air shutter adjustments, or low gas pressure. A yellow flame may produce carbon monoxide, which is hazardous and inefficient as it wastes fuel.

3. Orange Flame
An orange flame is another indicator of incomplete combustion. It can be caused by similar issues as a yellow flame, such as inadequate air supply or a burner that needs cleaning. An orange flame may also produce soot, which can accumulate on pots and pans, and potentially release carbon monoxide into the air.

The difference between blue and yellow flames depends on how well something burns. Blue flames mean complete burning. Both propane and methane burn blue. Red or yellow flames mean something might not burn properly. This can waste gas and be dangerous. Blue flames are good.

When gas burns blue, it's safe. If it burns red or yellow, it might not be safe. Flame color shows how hot and how well something burns. Blue flames are hottest, then yellow, orange, and red. Gases like propane burn blue. Wood and candles burn yellow, orange, or red.
