Perhaps this question has come to your attention, how hot does wood burn? Is there a specific temperature in which the wood starts burning? Basically, what is the temperature of the fire flame caused by burning wood?
It’s not easy to answer these questions. But in this article, we have tried to give a complete answer to questions like these.
What Is Burning of Wood?
Burning or combustion is a chemical process.
For many years, it was believed that the firing process should be described by the concept called the “fire triangle“.
This concept indicated that three elements were needed to create and continue the fire: oxygen, heat and a source of fuel.
In recent years, the fire triangle has been replaced by a fire pyramid. In this concept, another element added to the elements known as the Chemical Chain Reaction.
Oxygen In The Fire Pyramid:
In the case of oxygen, the air is the most common source of oxygen and has 21 percent oxygen content. It should be noted that oxygen sources can also include oxidizing agents.
Fuel In The Fire Pyramid:
The fuel intended for the fire must be flammable. As you know, wood is one of the most famous natural fuels.
Fire Caused By Burning Wood
To answer the question of how hot does wood burn, We first need to know what is fire?
Now we know that the fire is made of a large number of elements and certainly there is no fundamental definition!
In most cases, the fire is a hot mixture of gases; and the flame is the result of a chemical reaction, which is mainly carried out between air oxygen and fuel like wood. See what is wood made of?
The result of this reaction is carbon dioxide, steam, light and heat.
Wood Combustion Products:
- Carbon monoxide
- Carbon dioxide
But what happens when wood burns? Let’s examine the stages of combustion of wood together.
Stages of combustion of wood
1- Warm up to 120 Celsius degrees (248 Fahrenheit degrees)
Wood does not burn at 120 ° C, but gradually turns into charcoal.
2- Increased heat to 260 to 450 Celsius degrees (500 to 842 Fahrenheit degrees).
As the temperature increases, the wood starts to smoke and burn. At this point, the fire turns on with yellow light.
3- Heat from 450 to 620 Celsius degrees (842 to 1148 Fahrenheit degrees).
At this temperature most wood kinds comes in full combustion.
4- Charcoal burning
When the wood turns to charcoal, its temperature can be around 1100 Celsius degrees (2012 Fahrenheit degrees).
The Maximum Wood Burning Temperature In The Stove
Various factors affect the temperature of a stove.
Factors that determine the temperature of a stove are as follows:
- Wood type
- Wood moisture
- Amount of air entering the furnace
Wood kinds are also different: density, structure, as well as the composition of the resin and its amount. All of these factors directly affect the amount of heat, the nature of the flame and the combustion temperature.
For example, spruce wood burns with a very light flame, but its maximum burning temperature is only 500 ° C (932 Fahrenheit degrees), and this is not enough for heating.

But when burning such species as ash wood or hornbeam wood, the temperature is over 1000 Celsius degrees (1832 Fahrenheit degrees) that helps to warm up.
On the other hand, the moisture content of the wood affects its amount of heat. As far as the firewood dry burns hotter.
If the humidity of firewoods increases by at least 15%, their heat emission will be reduced by an average of 3,660 calories, and this is an important difference.

Also, more air will make the stove hotter. The temperature varies in different places of the stove.
The upper part of the stove is usually hotter. The temperature can be up to 850 Celsius degrees (1562 Fahrenheit degrees) in the center of a stove. Compare this temperature with iron melting temperature at 1538 ° C.
In this article, we saw that at 260 to 450 Celsius degrees (500 to 842 Fahrenheit degrees), almost every kind of wood burns and fire flames can reach to 620 Celsius degrees (842 to 1148 Fahrenheit degrees). To answer the question of how hot does wood burn, it must be said that it depends on several factors such as:
- Amount of oxygen
- Amount of moisture of wood
- Kind of wood
But generally, it can be said the temperature can be up to 850 Celsius degrees (1562 Fahrenheit degrees) in the center of a stove.
