The pellet between wood and gas pellet stoves and boilers
Biomass and an inexhaustible source renewable biomass is defined as all organic matter of animal or vegetable, except that which has been subject to fossilization. Oil, coal, natural gas, therefore, not covered by biomass. It must be said that in fossil fuels, especially oil and its derivatives, in the process of fossilization have formed groups and aromatic nitrogen compounds and sulfur, for combustion, produce toxic and carcinogenic substances, poorly degradable compounds easier it is for this reason that can not be bring them into biomass.
So between the wood and biomass are the derivatives of his work (or pressed sawdust pellets, wood chips), biofuels such as biodiesel, bioalcol, etc., made from fermented sugar beet or squeezing sugar, sugar cane, corn, canola, sunflower, etc.., biogas derived from anaerobic digestion of animal waste. The advantage of using these fuels is that you do not go to increase the concentration of CO2 in the atmosphere as carbon dioxide, produced by the combustion reaction is the same as the plant or animal are stored for through their metabolism. In the case of plant biomass burning is an indirect way of using solar energy, energy driving photosynthesis. We are talking about the carbon cycle, a process in which the atom, main element of life, becomes part of molecular chains more or less complex, while the principle of conservation of matter
and absorbing and returning energy. It is energy that man needs to warm up, to move, but at what price? It really is time to think about how to save our planet, without having to sacrifice our wealth and our comfort.
The pellet and its applications
If the wood is the most popular form of biomass, it needs space and not a few efforts to bring it from producer to consumer. Also replace a conventional boiler with a gas stove be connected to the heating and produce hot water for sanitary means a work of no small importance.
solution we give the stoves and pellet boilers. The pellet sawdust pressed into cylinders of 6 mm in diameter. It is sold in sealed packages of 15 kg of product, then the advantage of being easily transported and stored and not dirty. The pellet stoves and boilers have a tank that must be filled on average once a day and requires you to load more than the fuel must also provide for cleaning of the crucible of combustion, simple operation that takes very little time. For the rest takes care of everything on the boiler that automatically loads the pellets and automatically turns on the flame.
The types of pellet stoves in trade are more types of pellet stoves:
- The air pellet stoves or pellet through a fan that spread the heat of the flame in the environment are the cheapest category of products in pellets, but they are useful only to the environment where it is installed stove and it is difficult to heat adjacent rooms.
- The channeled through which you can move the air through ducts in the ventilated altrilocali different from that in which the heater is installed
- The hydro-or thermo-pellet stoves and pellet boilers to replace the boiler fully traditional, in fact they may be connected to the system without pre-existing changes mean that instead the installation of thermo-wood stoves or fireplaces thermal. They, according to the diagrams, can be installed in parallel with a traditional boiler, or sunglasses and perfectly able to do heating and domestic hot water.
 |
| In this scheme, the thermo-heater is installed in parallel with the conventional boiler to gas. So, either one or the other work for heating, while the gas boiler is also intended to produce hot water. | |
 |
| In this scheme, however, the thermal pellet stove or heater to fully replace the gas boiler for heating and for producing hot water for sanitation purposes. This service can be made through the medical kit supplied by the manufacturer, or externally by means of a kettle. |
Economic advantage Take as an example a house of 100 sq m (ceiling height 2.70 m) which requires an average of 17,000 kWh during the winter heating to be heated. We see the following table comparing the costs of using different fuels:
 |
(*) Pellet quality certified, there are also non-certified high-quality pellets that have lower costs also
buy the pellet out of the winter season, the costs are also halved. To calculate the consumption on your home simply divide the total expenditure by 100 and multiply by the area of \u200b\u200byour home. |
It must also take into account the fact that diesel, LPG and natural gas are fuels whose price is tied to the oil market, and will rise further over the years, while the pellets, a fuel is not being linked to international economic policies, will not be large price changes.
environmental benefits Burning pellets means returning to the atmosphere the same amount of carbon dioxide that the plants from which they used to grow, so it is a renewable energy and eco-friendly and more, since the dust a waste product of wood processing, is a way to recover the energy that produced that would otherwise be lost with its disposal.
The fire has always been an important element in human life. His discovery was an important step in the evolution of the human species has helped us overcome the darkness, to keep out wild animals, to make our food healthier, defeating many illnesses related to consumption of raw foods, the focus, then, has always been a sacred symbol in all the religious rites of human history. A former presence of which, with advancing technology, there are private, but now also the protagonist in the more modern furnishings.
The pellet then is a good compromise for those who love the comfort and savings, but do not want to deprive ourselves of what is energy for our home but also energy for our spirit, fire.
