Solid fuel stoves of long burning: reviews and prices. Is it possible to make a stove on solid fuels for prolonged burning with their own hands?
For most regions, the gaselectrical equipment is still not available at the moment. The first is due to the lack of gas distribution networks, and the second is due to too high electricity tariffs. And the question of using solar energy or geothermal sources for heating in the Russian outback is not even worth it.
Convection equipment in the West appearedquite a long time, and there it is actively used, but in Russia it is hard to get used to. Only after the ingenious professor and engineer Butakov created solid fuel stoves for prolonged combustion, such devices began to appear in Russian homes. The basis was a similar design of imported furnaces, in which he made some changes, so that the results of the work became much more effective.
Features of the design and distinctive features
First of all, Butakov changed the formfurnace. Domestic appliances were not cylindrical, like those of foreign counterparts, but rectangular with truncated upper corners. Thanks to this form, it was possible to significantly increase the heat transfer in the pyrolysis gas combustion process. The whole complex of changes and the tubular heat exchanger in the furnace on the solid fuel of the long burning of Professor Butakov underwent a whole complex of changes. The main transformation was the placement of the intake holes of pipes as low as possible, at a height of no more than 100 millimeters from the floor level.
The next practical and visual difference,introduced by the inventor, was a protective casing that was located above the heat exchanger and closed the entire furnace completely. Thanks to this addition, it was possible not only to increase the temperature of air heating in the heat exchanger itself, but also to increase the diameter of the pipes used, and this makes it possible to increase the volume of heated air. The surface of the protective cover in the upper part of the furnace is flat, which allows it to be used as a cooking chamber, on which food is warmed up and water is heated for household needs. Solid fuel furnaces of prolonged combustion with maximum heating allow not only to produce heating, but also to prepare food.
The equipment has a rectangular shape, due to which it can now easily be entered into any interior of modern or rustic style.
Principle of operation
Solid fuel stoves for long-term burning outDepending on the model, they can work on one of the types of natural fuel: wood, pellets, eurodrova, chips and sawdust, borax and coal. If we consider that their device uses the pyrolysis method, which burns wood gas in the secondary furnace, then natural wood is the most suitable option for fuel. The better the tree is dried, the more gas it can produce, that is, give more heat as a result of the operation of the entire system. The fact is that from a moist tree you get wet smoke that connects with gas particles, because of what they become heavier and do not burn completely.
The process of burning wood fuel occurs inthe main combustion chamber located in the upper part - there is a small burner. Through it, the resulting pyrolysis gas enters the secondary combustion chamber, where it is re-burned, giving heat to the heat exchanger tubes passing inside. Long-burning furnaces do not use a forced air intake system. The supply of oxygen is carried out through an adjustable damper, which is quite enough to saturate the secondary chamber.
The lower part of the furnace is equipped with a small container,in which ash is collected. The residual products of combustion are poured into it through the grate, which serves as the bottom of the furnace. The ash pan in the furnace design is used to clean the heater of the slag that has accumulated in it.
The branch pipe for connecting the chimney in thisequipment also differs in its location from convection ovens of foreign production. It is not accidentally placed vertically. Due to this, the rapidly forming condensate flows back to the combustion chamber. This became relevant due to the fact that in the condensate of such boilers there is up to 35-40% of unburned pyrolysis gas, evaporated from moisture, and then consumed. The vertical arrangement of the pipe makes it possible to install the furnace as close as possible to the walls of the room. For smoke removal in this design it is allowed to use any chimneys, starting with a simple metal pipe, ending with glass, ceramic or sandwich-pipes, so now popular.
The design features and characteristics have madeThe solid fuel boilers of long burning are very much in demand. The installation scheme is chosen depending on the room where the equipment will be installed. It is recommended to equip the place with heat-insulating screens. Free space should remain at least 150-200 millimeters from the furnace body to the walls, which allows you to protect the finishing materials from overheating and ignition. Near the oven, wood can be stored, thereby partially drying it before use for its intended purpose.
Automatic solid fuel boilers of long burning
Their appearance allowed not only to makeliving in houses more comfortable, but also to solve issues related to energy conservation, environmental protection, as well as saving on fuel purchases. In addition, it should be noted the improvement of the operational capabilities of the equipment, since it does not need constant supervision, as previous models. Heating systems that run on solid fuels have great prospects for today.
Automatic solid fuel boilersburning at the moment are widely used for heating houses, cottages, greenhouses, offices, shops, industrial and industrial buildings, car washes, service stations and other facilities. Many Russians abandoned boilers on gas in favor of devices operating on solid fuel.
The best solid fuel boilers of long burning have a number of undeniable advantages:
- The highest degree of economy is ensured by the fact that in Russia it is much more efficient to heat solid fuel than electricity or diesel;
- Opportunities for installation in areas where there is no gasification;
- solid fuel is a renewable source of energy, which makes it a rather profitable option for use;
- burning mode does not need constant monitoring - the best solid fuel boilers of long burning provide combustion of fuel without human participation for a week or longer.
Operating conditions of the device
For the device, you need to create certainconditions of work that will ensure the greatest effectiveness. First of all, this is the boiler group, which includes the boiler itself, the expansion vessel, the circulation pump, the safety group and other elements. A chimney must be required, which must be selected according to the results of the calculations performed, which does not allow the appearance of insufficient or excessive draft. Heating in the house will be organized through the use of a heating main, consisting of radiators and pipelines.
Solid fuel stoves for long-term burning with their own hands
Of all the variety of boilers that can beperform independently, rectangular will be the most aesthetic and compact. They are suitable for heating small rooms, and if they are finished, you can warm up and the area is larger. The design of solid-fueled long-life boilers is quite simple, and for its implementation, quite accessible materials will be required, the number of which depends entirely on the size of the future unit. The whole point here is to keep the heated air from direct exit into the chimney. For this, devices are installed inside, which consist of pipes and plates welded to each other in a special way, which makes it possible to create a kind of labyrinth between them, which ensures the slow passage of heated air through it. With a properly organized supply of additional gas, the upper compartments serve as chambers. If desired, the unit from the inside can be overlaid with brick or fireclay tiles. You can make a brickwork outside the appliance.
Self-made solid fuel boilersCombustion requires the use of certain components: a metal sheet with a thickness of at least 3 millimeters, a steel corner and a cover for a hole in the furnace, a chimney of suitable configuration, diameter and length. To begin with, all the details need to be cut in accordance with a pre-made plan. Next, carefully cut, polish or polish the edges. Only with full compliance with the developed plan can you get high-quality solid fuel boilers of long burning. The scheme of such devices should contain the names of all components and the location of their exact location.
Prices and reviews
Reviews about equipment in this categorydemonstrate its highest efficiency and economy, especially in conditions when other types of fuel are simply not available. Solid-fuel long-burning boilers of cast iron, produced in Russia, are usually much cheaper than foreign analogues. Usually the price of such devices varies between 400-900 dollars, while imported products cost an order of magnitude more.
Solid fuel boilers of long burningCast iron not only has obvious advantages, but also is characterized by increased heat transfer, which is ensured by the special properties of the material used.
