Pellets - a wood fuel pellets that are compressed waste wood production. Dimensions of wood pellets are 6 - 10 mm in diameter and 0.5 - 70 mm in length. Calorific value of pellets is 5 kWh per 1 kg (4500 kcal/kg).
Pellets are produced without any chemical additives, so they are environmentally friendly type of fuel. One of the main advantages of pellets, a fuel that can automate the process of filing of the boiler, and, consequently, the boiler. In addition, the pellets easily stored and transported.
PYROLYSIS BOILER - for addressing heating houses and small buildings.
Solid boilers with combustion pyrolysis. Such boilers are called gas producer. The main advantages of these boilers are in a higher efficiency (up to 85%) and possible power control (typically in the range of 30 to 100%). The main difference from the pyrolysis combustion boilers is that they burn not only the wood, but wood and gas allocated to them under heat. During this combustion soot is not formed and appears minimal amount of ash. In boilers with combustion wood pyrolysis gas that occurs due to high temperature in a bunker fuel, through a special nozzle and burns very clean flame yellow or almost white. The disadvantages of pyrolysis boilers include the need for power and higher than traditional solid-gas producer tsenu.V boilers boilers normally can burn all types of wood, wood waste or wood briquettes with humidity less than 20%. Among the manufacturers of boilers burning wood pyrolysis is especially worth noting Czech boilers of "OPOP" (CZ).
WHY same pyrolysis boilers can run on one tab of fuel per day and even longer? Clearly, the time of their work may be measured over a wide range depending on many factors, namely: the temperature outside, the required temperature in the room, the degree of home insulation, fuel type and moisture, but also on how properly designed and installed heating system. But certainly one - Pyrolysis of traditional boilers significantly better.
WHAT IS THE REASON?
Firstly, the burning of wood, especially moist, it is impossible to achieve such high temperatures as the combustion gas derived from them. Secondly, for the combustion gas to less secondary air than burning wood, so higher temperature combustion and, consequently, efficiency and burning time. Thirdly, the pyrolysis gas combustion process easier to manage, because the work of the boiler gas producer subject to automate virtually the same as gas or Vertical.
WHAT IS PYROLYSIS?
The study is based on the principle of the boiler gas producer combustion pyrolysis (or dry distillation) of fuel, the essence of which is under the influence of high temperature and under dry oxygen decaying wood on the volatile part - the so-called pyrolysis gas and solid balance - charcoal (coke). Pyrolysis of wood is at a temperature of 200-800°C. And this process is exothermic, that is with heat generation, thereby, incidentally, improves the heating and drying fuels in boilers and heating is supplied to the zone of combustion air. Mixing oxygen with air to select the pyrolysis gas at high temperature causes the combustion process last used in the future for heat. It should be noted that the pyrolysis gas in the combustion process interacts with active carbon, resulting in smoke gases leaving the boiler practically harmful impurities, as, for the most part, a mixture of carbon dioxide and water vapor. Even a pot of CO2 in the atmosphere will be throwing to three times less than normal wood and, moreover, coal boiler. In the process of pyrolysis combustion produced the minimum number of soot and ash, so the pot less than usual, needs cleaning. Due to the special design of boilers, incineration is the method of pyrolytic distillation, during which all the combustible components of fuel converted to gas. Combustion occurs in certain areas of the boiler. This method ensures high combustion efficiency of the boiler. This power is infinitely adjustable in the range from 5% to 110%. Boilers with pyrolytic incineration principle have a high degree of manageability. Long working hours without dozavantazhennya day and make them more attractive for comfort heating.
FEW WORDS ABOUT FUEL.
Pyrolysis boilers recommended drown as possible dry timber, then provided the boiler at maximum power and long life. For example, a tree, with 12-20% m-water content has calorific value of 4 kW/h per 1 kg of wood, wood with a 50% m of water content has calorific value of 2 kW*h/1 kg of wood. Calorific value of fuel depends on water content in wood. Useful energy content of wood is significantly reduced depending on how it contains water. Crude wood warms a little, poorly lit, smoke heavily and significantly shorten the life of the boiler and chimney pipe. Power boiler is reduced to 50% and fuel consumption will increase twice.
