Pyrolysis boilers: reviews and practice of application

For sure with the problem of heating a country house came across everyone who has it. Until recently, a real "hit" were ordinary brick stoves. Of course, they are still encountered, but today alternative methods of heating are more popular.

For example, pyrolysis boilers. Feedback indicates that they allow you to maximize fuel savings, giving the maximum efficiency. So, even a small and inexpensive boiler of this type will allow you to heat a large country house.

Operating principle

Of course, if you know the physics and chemistry well, then you do not have to talk for a long time about the principle of action, but for the rest you need to remind it. The fact is that when burning wood in an ordinary wood stove, fuel burns throughout its volume, releasing a significant amount of heat, most of which ... flies into the pipe.

But the pyrolysis cauldrons, the testimonials of which indicate exactly the same, are based on the "top" burning. In this case, only the upper layer of firewood burns, and the lower layer is exposed to high temperature in the absence of access to oxygen. In such conditions, carbon monoxide (combustible, by the way) begins to be released, and the firewood is partially converted to coal.

Positive features

Reviews admired buyers indicate that even a couple of piles of firewood gives off so much heat that it lasts all day. This is due to the fact that both the wood and the carbon monoxide released from them are combusted. The quality of combustion is such that even soot does not form.

In addition, boilers pyrolyzed, reviews of which are often emphasized precisely this circumstance, produce an extremely small amount of ash. You very rarely have to clean chimneys and a compartment for collecting ash.

Some shortcomings

As with any technology, even pyrolysis burning has some negative features. So, unlike classical stoves and fireplaces, they need electric power. It is necessary for the functioning of the smoke removal mechanism, since there is simply not enough conventional traction.

In addition, pyrolysis boilers (the reviews of which are especially emphasized) need high-quality and absolutely dry fuel. Of course, you can use even half-baked firewood, but you can not wait for high returns in this case. And ash will be formed much more.

Users claim that it's better to throw a portion of normal firewood into a firebox than complain about the low temperature in the house.

Cost

The widespread use of such heating devices in our country is hampered by their cost. Quality foreign pyrolysis heating boilers cost from thousands of dollars, so not every owner of a country house can afford them.

Can I make them myself

Strangely enough, even such complicated mechanisms can be done at home. Of course, homemade pyrolysis boilers will not have such a high energy efficiency, but still they are much better than simple stoves. Of course, that in the manufacture it is necessary to use only the highest quality materials and to make only hermetic connections that will prevent the ingress of air.
