While Wood Fire Temperature may not appear to be an essential factor, the temperature at which your wood stove works is crucial concerning its efficiency. When the furnace is at optimum Wood Fire Temperature, wood combustion is better. In other words, burning wood will mainly produce heat, water vapor, and carbon dioxide. With incomplete burning of wood, you get unwanted by-products, such as smoke, excess carbon dioxide and creosote whip-clogging. Learning this process will help you keep your stove efficiently.
The study of burning materials is not entirely straightforward. In addition to heat, there are many factors to consider, like kinetics. Kinetics is how fast is the reaction.
When the fire burns as a source of heat, we need the energy to start the combustion process. When the process begins, there needs to be a constant source of energy that allows increasing the activation energy.
The combustion process requires wood. When wood burns as fuel, small molecules and gases liberate from wood surfaces when there is a heating wood. The gases react with oxygen in the air to produce combustion products and heat.

What is the Best Wood Fire Temperature?
The energy content or Wood Fire Temperature comes in BTU (British thermal units). The standard method to estimate the Wood Fire Temperature is to state the BTU and compare it with your needs.
The wood releases a certain amount of heat. Trees with high Wood Fire Temperature are elm, maple, and red oak. Softwoods, like white pine, basswood, green ash, and white spruce are very dense and burn more time with the same heat capacity.
Wood Fire Temperature and Color
Fire is the result of the chemical reaction between fuel and oxygen. When the reaction produces enough heat, flames form. Flames change color over time and often have multiple colors in different parts.
The two most distinctive properties of fire are heat and color. The color of a flame relates to the temperature. You can estimate the temperature of fire by identifying the intensity of the light.
It is frequent to use of blue as a cold color, and red as a hot color. Nonetheless, the reality is the opposite for fire flames. Red is generally on the outer edge of the blaze. On the exterior, the Wood Fire Temperature is lower than the inside. Contrarily, blue is the hottest temperature.
The warmest part of the flame is the center. This reason is why the center usually burns with a color different from the outer edges. The blue flames are the hottest, followed by the white ones. Then, yellow, orange and red are the primary colors you can see in fires.
Wood combustion is a complex chemical reaction. When it begins initially, all that happens is that the water in the wood dissipates or vaporizes. This method uses the initial energy. When the wood equals 500 degrees Fahrenheit, it decomposes chemically. At this point, you get volatile gases, and you can feel the heat of the reaction.
When the temperature approaches 1,100 degrees Fahrenheit, gases and smoke burn reacting if they have enough oxygen. The remaining coal of the reaction burns at temperatures above 1,100 degrees Fahrenheit.
There are ways to burn smoke and volatile gases without raising the wood temperature to 1,100 degrees. For example, some stoves have a catalyst inside that causes the smoke to burn at only 600 degrees Fahrenheit.
Non-catalytic stoves use circulating air to burn more efficiently smoke and gases and are easier to use and maintain than catalytic stoves. However, catalytic stoves can burn wood more slowly. Also, those stoves can cook at a lower temperature than a non-catalytic stove, and still work correctly. This makes catalytic stoves more efficient.
The theoretical maximum for a fire-based carbon in the air at the standard atmospheric pressure is around 4500°F / 2500°C if you use pure oxygen instead of air. Also, if you increase the air pressure, it can become even hotter.
Standard firewood limits to a maximum of about 1600°F / 900°C. However, you can do it in stages. First, the conversion of wood into charcoal by burning in an environment with limited oxygen, and forging, which blows air onto the coals that burn. Then it can get much hotter, at least 2500°F / 1400°C. This state is close to the melting point of iron.
How To Control Temperature
You can adjust Wood Fire Temperature in a stove with adjustable vents that allow oxygen to reach the fire. You can open the vents to increase the oxygen inside the grill allowing more fire, which provides a hotter burning. Also, holes can reduce oxygen around a radiator, which reduces the temperature.
For such a small flame, a domestic match burns at about 600-800°C.
An exceptional Bunsen burner is adjustable, with safety flames measuring about 300 °C. Bunsen burner fully open can reach 1500°C, with visible blue and white penetrating flames.
Hardwood vs. Softwood
Different woods produce different levels of heat. For example, dry wood emits more heat than wet wood. This fact is because, in the initial chemical reaction, all the heat evaporates or vaporizes the water. Therefore, the less water there is, the more heat you can feel.
Different wood species emit different amounts of heat. In general, hardwoods burn more than softwoods and emit more heat. Some species with a high caloric value include walnut, red and white oak, yellow birch and sugar maple. Species with a low caloric value include redwood, cotton, hemlock, and Alamo.
Hardwood has a higher score in thermal energy for a volume of wood. Therefore, they are a better stick for heat and Wood Fire Temperature. However, they are more challenging to do the ignition first.
Coniferous trees have low density and tend to be more resinous. This fact means they ignite much faster. Therefore it may be better to start with trees that the fire is burning. However, they generally produce less heat and burn more quickly.

Best firewood – Ash, red oak, white oak, beech, birch, walnut, maple, walnut, cherry, dogwood, almond, Apple (incense-a nice perfume)
Nowadays, there can be different temperatures in different parts of the fireplace. The highest temperature in the majority of the fires come after the fire has been going for a while. These temperatures are between 1200 degrees to 1500 degrees Fahrenheit. However, since so much air circulates the fire, grids and other nearby objects unusually exceed 1000 degrees.
Nonetheless, gas fire burns at a lower temperature, with the grill also being the hottest part in about 1000 degrees. This fact is evident because the grids sometimes shine. Also, the iron shines at approximately 1000 to 1100 degrees Fahrenheit.
Keeping a stove warm to avoid fires may seem counter-intuitive, but it is logical at the chemical level. Creosote is a tarred substance that prides itself on the chimney as part of the smoke. The sticky creosote obstructs the shot and prevents good circulation. Moreover, it is highly flammable.
The typical cause of a fire in the chimney is the burning of creosote inside the fireplace. There are many methods to combat or prevent this. One of the ways is to keep the shot hotter than 250 degrees Fahrenheit. The temperatures above this point are too high for the creosote to condense on the surface of the chimney.
