Wood is used in many areas of everyday life. The most popular and economical type of fuel is used for heating residential premises and baths. The burning temperature depends on the wood species, the moisture content of the raw materials. The higher the temperature, the more efficient the heating of the living space.
What is the temperature in the furnace when burning wood
Firewood burning is an isothermal reaction in which thermal energy is released. Heat transfer directly depends on the height of the fuel combustion temperature. Well-dried firewood burns much better than oversaturated moisture. Before harvesting environmentally friendly fuel for the winter, you should study the characteristics of each tree species.
Depending on the type of firewood
Various types of trees suitable for harvesting firewood differ in density, wood structure and chemical composition. A more efficient heating of the room is possible using well-dried raw materials with a dense texture. Such firewood burns completely, do not leave a lot of ash. The combustion temperature in the furnace varies from 800 to 1000 degrees. Deciduous tree species have long-lasting burning properties: birch, linden, oak, ash. Firewood with a looser density burn faster, but have low heat dissipation. Therefore, it is disadvantageous to use such firewood for heating. Fir rocks produce little heat and emit a large amount of soot and smoke. They are good to use for open areas, for example, when frying kebabs.
Attention! The completeness of burning of logs does not always depend on the type of wood, the internal structure of the furnace is of great importance. Quality stoves are equipped with elements to increase the heat transfer of fuel.
Oak wood has a dense texture and flames up to 900 degrees in the kiln. Birch firewood gives heat at a temperature of 800 degrees. Poplar has porous wood, and can only give a low burning rate of 500 degrees. When firing in a bathhouse or in the open air, it is not cost-effective to use raw materials with a dense structure; it is better to fire with cheaper tree species with the addition of a small amount of birch or oak logs for heat. In an open fireplace, it is better not to use alder raw materials. When burning, they tend to shoot with coals, which can lead to a fire hazard.
Additional factors affecting furnace temperature
The moisture level of firewood plays a huge role in kindling and transferring heat to heat a room. If the wood is raw or poorly dried, during combustion part of the heat will be spent on removing excess moisture by evaporation. The temperature in the furnace will not reach the maximum percentage of heat transfer.
To completely burn wood and achieve a high temperature, it is necessary to regularly supply air to the furnace. Without the right amount of oxygen, the logs begin to smolder and do not emit the full amount of heat into the room. If you supply too much oxygen through an open blower, irrational loss of heat transfer will occur through the chimney. Therefore, it is necessary to install furnaces with good equipment of important elements. Blower, grate, flaps must be in good condition.
The maximum output of heat and heat during combustion is affected by the design of a home stove. What material is it made of, how are the dampers and the blower working - everything can affect the generation of heat transfer. Steel furnaces cool quickly, not having time to heat the room to the desired rate. Equipment made of more massive material keeps heat longer, and logs flare up as much as possible. But, such stove devices require constant monitoring. Due to the high heat output, an explosion may occur.
The combination of all factors directly affects the combustion process. To generate the maximum amount of heat, it is necessary to use well-dried fuel and provide the combustion process with the right amount of air. Do not heat the furnace with rocks with a porous texture. This will be a rather expensive undertaking.
How to measure the burning temperature of firewood
At home, it is quite difficult to measure the temperature yourself. It is necessary to purchase a special measuring device - a pyrometer. Specialists conducted the necessary studies, and derived data on the maximum burning of various tree species. It remains to rely on the measurements taken, and take care of high-quality furnace equipment. Modern furnaces are equipped with convenient regulation of the timely supply of oxygen, so that the output of maximum heat during combustion can be controlled.
You can determine the approximate combustion temperature by the color of the flame of combustible wood in a Russian wood-burning stove. When burning rocks with low heat dissipation, the color of the flame will be dark red. If a birch or oak burns, you can admire the light yellow fire.
Important! The process of burning wood in stoves must be constantly monitored. Any flooded stove is a place of increased danger.
Based on the measurements of the combustion temperature in laboratory conditions, it is possible to make the choice of the most suitable type of fuel. High heat output is characterized by ash, hornbeam and beech wood. Oak and birch have a lower indicator, but are great for high-quality heating of residential premises.
