Pyrolysis long burning boilers with a water circuit

Pyrolysis boilers long burning - a modern alternative to gas heating in a private house

What is Pyrolysis and performing well

Medieval Europeans as a result of many centuries firewood combustion found that this energy can be used more efficiently, if not put in the oven wood, and charcoal. Produced by burning its ordinary wood without sufficient oxygen. To do this, dig a special hole in the ground, where he came all this process, later called pyrolysis.

Some types of continuous burning boilers pyrolysis

Such pits copes with the task of charcoal, but the energy that was released in the course of these processes, was spent without any benefit. It is said that the amount of released energy was very decent. Therefore, modern technology was not spared such a gift of nature. Pyrolysis long burning boilers were set up with a water circuit that is able to curb the heat used previously wasted. Today, they are successfully used not only as an auxiliary heating source, but also as a major. This is not surprising, because in addition to conventional wood, they can be loaded and the other, more modern and fuel efficient wood-based.

Externally, these boilers are not much different from the usual metal furnaces. They have the same loading door leading into the primary combustion chamber. It fit regular firewood and briquettes from sawdust or peat. Used for these purposes and the invention of the last few years - granules pellets. They are a highly compacted waste joinery production. The case goes all the way from the bark of trees and ending with peat and dried manure.

Useful advice! It is best used as a fuel pellet granules. This fuel has a small size and can be automatically supplied to the boiler combustion chamber.

At the bottom of the combustion chamber is located grate having the form of a very heavy cast iron lattice. It is necessary to supply air under fuel. Loaded wood ignited and wait until they are completely flare up under the influence of the primary air flow. Once the boiler goes to mode access of air to the primary chamber substantially terminated, whereby the combustion is stopped. Fuel only starts to smolder, producing pyrolysis gas. He has a very high flammability, but since the air is small, it does not flash.

Then gravity or force the gaseous mixture of volatile organics fed to the secondary chamber, which actually is a main working portion of the pyrolysis boiler continuous burning. With the water circuit of the heating system it is connected directly. Entering into this chamber has a gas temperature of about 300 degrees and therefore breaks at admission oxygen without delay. In the secondary chamber is fed a sufficient amount of air for combustion. Pyrolysis gas given off during combustion is much more energy than ordinary wood, so heating the coolant in the system is very fast.

The important point is that the portion of wood placed in the furnace, consumed very slowly, which allows you to heat the room very small number of them for a long time.

Useful advice!As fuel for the gas generator is recommended to use a very well dried and the wood substance. After 1 kg of wood, which contain 20% moisture allocates 4 kW / h. energy, and containing 25% moisture, has only 3 kW / h.

• completely solved the issue of adjustment of the combustion process and heating fluid. Due to the fact that the gaseous fuel is burned in the chamber, its flow is easily adjusted, as well as the intensity of the combustion. This makes it possible to fully automate the operation of the boiler, no worse than an electric or gas.

It has long pyrolysis combustion boiler water circuit and disadvantages that should inquire the acquisition of this technique:

• gas generators cost is much higher than other types of heating equipment. However, it eventually pays off, thanks to fuel economy;

• Fuel must be perfectly dry. Already 20% of th humidity is a serious obstacle for combustion. The boiler just shall cease to operate after the air access restrictions;
• due to the fact that the design of almost all the models provided by the use of fans for circulating the air, then for their work requires electricity, which prevents the use of this technique in the cottages that do not have power.

Useful advice!Reviews owners pyrolysis long burning boilers say that sometimes they stop because of the fact that the water return pipe from the system enters the boiler circuit is strongly cooled. To avoid this, it is necessary to solder in a bypass loop of the supply pipe. It uses a conventional three-way valve. Then hot water is mixed with the cooled, the boiler will not be switched off.

Reviews owners pyrolysis long burning boilers

If you wonder what can be found on forums and blogs a lot of feedback owners pyrolysis long burning boilers. Here are some of them:

In the last year I put the gas generator at his dacha. Near a sawmill, where there is always a huge amount of chips of bark and twigs. Bury - I do not. Now do not Narada. Fuel is not spending. Waste brought a cart that took charge. I do not know when and consumed.

recently I purchased solid fuel boiler, A friend advised. Initially I did not understand why I did it, where to take and store firewood. And then I found that it is possible to use pellet beads. I bought a few bags. Fuels - grief do not know.

Pyrolysis long burning boilers - environmentally friendly and energy efficient due to the complete combustion of the solid fuel

My husband recently brought the miracle-stove that runs on conventional wood. I scolded him for a long time. She said that we have a gas pipeline and a gas boiler. Why do we still have this stove. He said I'll understand later and attach the device to the system, leaving a gas. One day in the village of pipeline breakage occurred. Working three days corrected the accident. Neighbors bought all electric heaters, and my husband just shrugged and melted his oven. Now I realized that I was wrong.

Reviews holders pyrolysis long burning boilers disclose all the positive qualities of the device. Use this device can really be a great benefit for themselves. As an alternative heat source, it can completely solve the problem of the temporary absence of gas. For those who have a possibility to use various waste products, it is a godsend.
