Understanding Why Your Firewood Produces A Blue Or Green Flame

Whether you want to use firewood in Perth for camping or you want to use it in your wood burning fireplace at home, it is important to know the best types of woods to use and those to avoid. Read on as we detail the problems with flame colour when firewood is burning. Flames can be in different colours and the variation in colours can be caused by a lot of things. Some colours are fine while others can indicate that something has gone wrong and you may be in danger.


If your wood burns with a blue flame then it means that it produces 2300 degrees or more while green flames may indicate that there is something else burning with the wood such as pesticides or chemicals.


A blue flame

Maybe the easiest change in colour to notice is a flame that burns with a blue colour. This is mainly because it is different from the traditional fire and perhaps the expected orange flame. In your science class, a blue flame indicates the intensity of the heat produced by the flame. The hottest part of a flame burns in a shade of blue while the rest of the flame burns with the normal orange colour.


You need to remember that if the entire flame is hot, the whole flame will burn blue. E.g., a Bunsen burner will be predominantly blue when the volume of the gas is turned up. So, what is the meaning of a blue flame when burning firewood? Blue simply means that the flame is burning carbon. This means that all the material being burned is carbon leaving no matter for the flame to light up and this is the cause of the orange colour.

If you notice a blue flame when your wood is burning then this could be caused by different reasons. One simple thing that may cause this is that there are a number of rusted nails in the wood. The oxidation of the iron nails can cause a blue flame and this means that the colour of the flame is not as a result of the wood.


However, if you know that your wood was free from iron nails or pins then the issue may be how your wood was treated. Pressure treated lumber contain copper compounds that may cause a blue colour when your wood is burning. If your wood is not pressure-treated then it may be just the type of wood you are burning that is causing the blue flame.


Is blue flame dangerous?

If you are burning firewood in Perth that is producing a blue flame, the good news is that, a blue flame is not dangerous. It means that no fuel is being wasted during the burning process. However, if you are using wood with an appliance, it is important to use a carbon monoxide detector to ensure that the appliance will not malfunction and that the colour of the flame doesn’t result from excessive carbon monoxide. If there is no toxic gas then your fire is safe.
