Boilers for solid fuels - market range, operation specifics

Boilers for solid fuels

What do people living innegazifitsirovannyh areas, because in the winter without heat in the house can not be? Boilers for solid fuels - a kind of prototype of the Russian furnace, but at times modernized and improved. Progress crucial because between them there is only a single thing in common - the type of fuel. The principle of operation of such boilers independent and autonomous, because they have no connection with either gas pipelines or electricity and central heating system. This is a definite plus for remote villages, because there are people, too, and they need civilization.

The heart of the heating system

Modern heating boilers for solid fuelsconsidered excellent sources of warmth and comfort in the house, one can create any climate, regulate temperature and does not depend on communication services, which are sometimes subject to breakdowns. And it is a very wonderful to live in their power (the house) and run the show, that is heating.

Quite often occur at home, cut off from thewealth of human civilization, and yet home to somehow equip and live in normal conditions. Yes, and it is unclear when there will be good communication. In this case, the acquisition will be an excellent solid fuel boiler.

It is clear that coal and wood - the main fuelboilers of this kind. It says that a person should take care of the replenishment of stocks. In addition, it is necessary to equip a special room where the fuel is stored, and it must be protected from precipitation.


The boiler in action

Another caveat - the boiler is necessary to watch,as one piece of coal or wood burns through and releases heat, and then require regular and timely necessarily fuel loading. The house should always be the person who will be responsible for the productive operation of the boiler, because "podkidok" will have several, for example, one batch of fuel is designed for 3-4 hours.

You can prolong the process of burning fuel,this should buy a solid-Jetstream furnace. When used not only prolonged combustion time, but also increases the effectiveness and efficiency. About his work in the article will still be talking, but a little later.

And another advantage of solid fuel boilers is "retraining" in the gas (a pipe suddenly still appears next to the house), then you need to simply change the burner.

Classification of solid fuel boilers

Such boilers are essential superiority -fuel economy: it can be coal, peat braces, wood, coke. Despite the peculiar alienation from civilization, these boilers are equipped with fully automatic control system, and are equipped with sensors, responsible for temperature, safety equipment.

Type heat exchanger material

Cast iron boiler

Cast iron solid fuel boiler

Boilers for solid fuel dividedtype heat exchanger material: steel or cast iron, while the fuel resources have identical. Cast iron solid fuel boilers are more durable because this material has a property for a long time to warm up and cool down slowly. But there are also negative aspects: these units are characterized by excessive fragility, which is caused by sensitivity to sudden termoperepady. As a result of "thermal shock" unit walls are gradually destroyed, and breaks down the boiler. Not so bad, now expired technologies improve and cast iron boilers have overcome fragility.

Steel boilers are more resistant to temperature"Whims", but also has its own nuances - a weakness for corrosion, and the reason for this phenomenon condensate. Cast iron boilers such an impact is not terrible, but in any case the duration of the service depends on the quality of steel, the thickness and the fact that the proper handling of the equipment.

By the number of loops

- Single-circuit boilers are designed exclusively for full room heating. Typically, in such boilers is thought possible to connect the storage water heater;

turbofan boiler

Turbofan boiler for solid fuels

- Combi boilers for solid fuels - onecircuit for heating, and the other, respectively for hot water. Boiler for solid fuels may have a different capacity, it can be calculated, thus focusing ratio: 10 sq. meters - a minimum of 1 kW boiler output. But it provided no more ceiling height of three meters and a good thermal insulation. And if the house heat loss is significant, the hot water system must be appropriate.

According to the principle of work

Using this parameter for solid fuel boilersdivided into classical and gas generators (pyrolysis). Heating boiler for solid fuels is working on such a scheme: the fuel is burned, and instead heats up the coolant (water). Using heated water radiator system heats the room.

Important: to classic boiler gave nameplate capacity and high efficiency, it is necessary to ensure the correct functioning of the air and the necessary draft in the chimney.

gasification boiler

Jetstream furnace

During the retreat from this recommendationreduced efficiency, excessive fuel consumption, and the heater prematurely fails. Gasification boiler for solid fuel based on the principle of pyrolysis fuel combustion. The bottom line is this: under the influence of high temperatures in an oxygen shortage conditions timber (dry) can be decomposed into volatile part, that is pyrolysis gas and a solid residue that is charcoal (coke).

Important: use temperature of 200 for the pyrolysis of wood - 800 degrees.

This process is exothermic, with release of boundheat, air oxygen and pyrolysis gas are mixed, resulting in the latter starts to burn and is then used to generate heat energy.

Gasification boiler to heat the most desirabledry wood, as a result of the work is provided at maximum power and long life. What is the difference between the consumer and the classic gasification boilers? Yes, that time between downloadspyrolysis boiler is increased at least twice. We should also note the fact that the flue gases coming out of such boilers, almost do not contain harmful impurities of the atmosphere, by and large it is a mixture of carbon dioxide and water vapor. Hence, they are more environmentally friendly and produced a small amount of soot and ash (this argument is very happy) in the combustion process, so it can be cleaned less often.

According to the type of automation

- Non-volatile - in such boilers, air flow is regulated mechanically;

- Volatile - air flow adjustment shall blowing fan, which is controlled by the electronic control unit.

By way of loading

Variety of solid fuel boiler

Boiler with a bunker

Method of fuel loading can be manual andautomatic feed (auger). Recently received a lot of popularity in Europe, and it is not surprising, because they are characterized by a huge advantage. That's just not all consumers are available because of the high cost and unavailability of used fuel - eco-peas. Depending on the type of burner may be employed and other fuels as coal with a grain size up to 2.5 cm, Pellets, dry wood chips.

heating boiler for solid fuel feedhas the main advantage - the hopper can be downloaded and no longer apply to the boiler about 3-7 days (depending on the size of the hopper). Also in this boiler is very high efficiency, minimal emissions, stable maintenance of the set temperature.

Important: for boilers of this type should be an autonomous power supply, simple bespereboynik not suitable here.

Proper use of solid fuel boilers

So, the dream has come true and you become the proud owner of a modern boiler. How to handle it? Naturally, you need to strictly follow the instructions and do not take willful action.

Good solid fuel boiler is equipped, in most models, the control unit, as well as boost fan, which maintains the temperature of the coolant.

control unit at all considered in the articleboiler operates one scheme: in the jacket of the boiler is a thermal sensor, it sends a signal on water temperature to the control unit. Therefore, if the temperature has fallen below the level set by the user, the control unit activates the boost fan, so catching up on the required temperature.

After reaching the desired level of fanoff, and the control unit sets the standby mode, that is corruption. In this mode, periodically and momentarily turns on the fan for combustion and removal of accumulated gas into the combustion chamber.

Ignition - crucial stage

Through the door shurovochnuyu laid papersmall chips for ignition, and a loading door add larger wood. If the furnace is provided with charcoal, then poured on top of stacked firewood little coal. Then the paper is ignited and given time to chip buildup. In the case of the recent operation of the boiler, chimney and well warmed up enough traction, you can close the door and just turn the control unit, thus setting the desired temperature of the coolant. Then, after some time, the control unit must be switched off and carefully open firebox door, to see firsthand that coal laid part already inflamed and can be added to the main batch.

Important: in this case the gap in front of kolossnikovoy grille is not closed.

Now all the boiler will take care of itselfmaintaining the temperature. The only low-quality coal coke can, so it is recommended to periodically move his pawn or fuel of the type "sandwich" - wood-coal, wood.

It is also necessary to remember that the full warm-upsystem heat exchanger walls (inside the boiler) is possible condensation. This is often a temporary phenomenon, if the normal circulation, condensation disappears.

Important: if the system is cold and the house, it is desirable to the boiler for a while worked at a high temperature, and only then can it be reduced to the required mark.

Ash - a mandatory work

Depending on the type of fuel must be periodicallyremove the ash, which is in the ash pan. Since wood is less hassle as she showered ash and slag from coal to remove a little harder. But the game is worth the candle, because the duration of the operation of the boiler on the corner with a longer loading 2 times.

Why do you need a circulation pump

By the control unit can be connected to a specialdevice - the circulation pump. Why is it needed? Such a pump is necessary if a long time is not gaining boiler temperature, for example, it ran out of fuel, then the anti-freezing mode is switched, and the pump is periodically drives off water in the system so that it does not freeze.

Rules for chimney

The chimney for the boiler

Construction of the chimney - a very important stage

Ideally, the chimney should be insulated, it canbe canned brick or sandwich pipe. Its height should be at least 6 meters, in this section depend on the type of boiler. Without the chimney will not work any solid fuel boiler, to save his arrangement is not necessary, it is bad for the service life of the boiler.

Solid fuel boilers - a great alternative tohouses, cut off from human goods. In the summer you can enjoy the purchase of fuel and the formation of, and in the winter enjoy the warmth and from no one to depend on. The classic version heats the home and hot water boilers for solid fuels in addition to heat and still provide residents with hot water at home, and this is another important aspect.
