No matter what changes progress has undergone, the stove remains the same attribute of a country house. The stoves are made of brick, iron or cast iron. They can be of different designs and appearance. But behind the stove in the house always remains the main function - heating the room. Also, these heat sources can be used as:
- Cooking appliances;
- Fireplaces
- Devices for heating water and steam.
Fuel can be the most diverse. But perhaps ordinary firewood will never lose its relevance. have a long service life, good efficiency. Using wood as a fuel allows them to be considered the most environmentally friendly among their counterparts.
No matter how modern wood-burning stoves differ from each other from the same devices from past centuries, the principle of their operation remains the same.
Principle of operation
In the design of a wood stove of any kind, there are necessarily several mandatory parts that determine its operation.
First of all, this is a combustion chamber. The volumetric firebox is used to load solid fuel, in this case, firewood. In addition to it, the stove has an ash box, a blower and a pipe. Depending on the purpose, the distribution of heat occurs in different ways.
The main principle of operation lies in obtaining high temperature due to the combustion of fuel. The resulting heat heats the walls of the furnace. The thicker the walls of the furnace and depending on the material from which they are made, heating devices can longer hold high temperatures and, therefore, have greater efficiency. In addition to heating the walls, heat can be directed to heating stones (stove-heaters), water (bath options), systems from tubes to produce steam and stoves for the kitchen.
You can control the combustion of firewood with the help of the blower door. By changing its position, it is possible to obtain the necessary oxygen supply to the combustion chamber (furnace), thereby controlling the rate of combustion of firewood and the amount of heat generated over a certain period of time.
Good stoves with one load of firewood can work from three to five hours.
Exhaust gases (smoke) go through the chimney. Passing through the whole house to the roof, the chimney itself is a heating system. Smoke enters the chimney and enters the surrounding area. Using firewood, you can not worry about environmental pollution.
Burned wood turns into ash and ash. An ash box is used to collect it, which can be quickly cleaned of combustion residues. Ash can also be used in the household as fertilizer for the garden.
Safety first
The device of modern wood-burning stoves allows you to completely avoid the unpleasant consequences that are usually associated with the use of open fire indoors. Ovens do not fade and do not pollute the surrounding air. They exclude the occurrence of a fire in the house.
And, importantly, wood-burning stoves are very economical means for heating.
