Heat through time or the principle of the operation of wood-burning stoves
Whatever changes are undergoing, butThe oven remains an unchanged attribute of a country house. Furnaces are made of bricks, iron or cast iron. They can be of different designs and appearance. But behind the oven in the house there is always a basic function - heating the room. Also these heat sources can be used as:
- Devices for cooking;
- Devices for water heating and steam production.
Fuel can be very diverse. But perhaps, ordinary firewood will never lose its relevance. have a long service life, good efficiency. The use of wood as a fuel, allows them to be considered the most environmentally friendly among their fellow humans.
No matter how modern furnaces that work on firewood differ from each other, from the same devices from past centuries, the principle of their work remains the same.
Principle of operation
In the design of a wood-burning stove of any kind, there are necessarily several compulsory parts that determine its operation.
First of all, it's the combustion chamber. The volumetric furnace serves to load solid fuel, in this case - firewood. In addition to it, the stove has an ash box, an ash-pit and a pipe. Depending on the purpose, the heat distribution occurs in different ways.
The main principle of work is laid in obtaininghigh temperature due to the combustion of fuel. The resulting heat heats the walls of the furnace. The thicker the walls of the oven and, depending on the material from which they are made, the heaters can hold the heat longer and therefore have a higher efficiency. In addition to heating the walls, the heat can be directed to the heating of stones (stoves-stoves), water (bath options), systems from the tubes to produce steam and plates for the kitchen.
The combustion of wood can be regulated with the help ofthe door of the door. By changing its position, it is possible to obtain the necessary flow of oxygen into the combustion chamber (furnace), thereby controlling the combustion rate of firewood and the amount of heat released over a certain period of time.
Good stoves-heaters with a single loading of firewood can work from three to five hours.
The exhaust gases (smoke) escape through the chimney. Passing through the house to the roof, the chimney itself is a heating system. Smoke enters the pipe and leaves in the surrounding space. Using wood, you do not have to worry about environmental pollution.
Burnt wood turns into ash and ash. To collect it serves as an ash box, which can be quickly cleaned of residues of combustion. Ash can also be used in the household as a fertilizer for the garden.
The device of modern wood-burning stoves allowscompletely avoid the unpleasant consequences, which are usually associated with the use of open fire in the room. Furnaces do not smoke and do not pollute the surrounding air. They exclude the occurrence of fire in the house.
And, importantly, furnaces that work on firewood are very economical means for heating.
