In general, firewood burns at a higher temperature than natural gas.
Firewood, such as logs made from wood, typically burns at temperatures ranging from about 700 to 900 degrees Celsius (1292 to 1652 degrees Fahrenheit) when it is fully ignited and burning efficiently. The exact temperature can vary depending on the type of wood, its moisture content, and other factors.
On the other hand, natural gas, which primarily consists of methane, has a lower combustion temperature. When natural gas burns in a controlled environment, it typically reaches temperatures of around 500 to 600 degrees Celsius (932 to 1112 degrees Fahrenheit). Again, the exact temperature can vary depending on factors like the air-to-gas ratio and burner design.
It's worth noting that the temperature of the flames can also be influenced by factors like air supply, ventilation, and burner design. Additionally, different types of firewood and variations in gas compositions can lead to some variations in temperature. However, as a general rule, firewood tends to burn at higher temperatures than natural gas.
