Given the ever-increasing cost of heat carriers, one should not be surprised at the fact that residents of suburban cottages in our country are constantly in search of an alternative way of heating. One of these is a solid fuel boiler for long burning. Customer reviews indicate that under certain conditions it will easily replace even gas equipment.
Principle of operation
It is known that the principle of operation of a conventional stove is based not only on the fact that hot air from burning firewood heats the house, but also on the ability of its bricks to accumulate heat, gradually giving it away. That is why stoves are much better than fireplaces that only give off the energy of burning fuel without accumulating it.
Creating a solid fuel boiler for long burning, reviews of which attract attention, manufacturers remembered that divalent carbon monoxide (ordinary carbon monoxide) can be extracted from firewood. It burns well and gives off a lot of heat. In addition, this equipment does not emit any harmful substances into the atmosphere, which is important for those regions where air pollution has become rampant.
The reviews of satisfied consumers indicate that with this approach there is very little ash and soot left, and the firewood leaves several times less than if they used even a high-quality stove!
How did you manage to achieve this?
Models, which include, for example, solid fuel boilers long burning "Buderus", work according to one scheme. Firewood is laid in the upper chamber. Air does not enter into it, and therefore the tree is converted into coal and the same carbon monoxide by pyrolysis.
It enters the middle chamber, where it ignites, simultaneously generating a huge amount of thermal energy. Of course, of the combustion products there is only water and carbon dioxide. Consumers who installed these boilers talk about the fact that their functioning requires the smallest and most primitive chimney, which does not need frequent cleaning.
By the way, heat from gas combustion is supplied not only for heating purposes, but also dries wood raw materials.
Job requirements
Here you should make a small digression and talk about the fuel that the solid fuel boiler consumes for a long time. The reviews contain information that even firewood with a moisture content of more than 50% can be thrown into the furnace. Someone admitted that he repeatedly drowned his "stove" even with half-baked sawdust briquettes.
True, these same people are annoyed to note that work efficiency is reduced. This is due precisely to the fact that most of the heat from the combustion of gas is no longer spent on heating, but on drying the wood. In addition, with this approach, more ash and even soot begins to form.
By the way, never forget to clean up “production waste” on time. If too much ash accumulates in the pan, then normal traction can not be expected.
What other fuel can be used?
It is not necessary to consider that a solid fuel boiler of long burning, reviews of which are mostly positive, can “eat” firewood alone. Coal and even peat briquettes can be thrown into it.
But experienced users of this kind of equipment show that the pyrolysis process on this type of fuel is not going well, little carbon monoxide is released. Accordingly, the heat output also becomes extremely negligible.
Financial issue
Solid fuel long burning boiler, the price of which varies from 7.5 thousand rubles to infinity, can be purchased by people with a variety of income statuses. In addition, spending a few extra thousand on a more expensive model, you will still return the money, stop paying for the ever-rising gas price.
