BIOMASS

The basic model of take up and accumulation of the solar power is the one that there carry out the plant green species the only energetic renewable source that carries likewise a storage in the shape of energy of high quality: the chemical energy. This process has supported the life in the Earth to the present day in the shape of organic matter, which turns out to be a stored solar power and is named a " energy of the biomass ".

BIOMASS FORMATION

NATURAL TYPES OF RESOURCES

Resources can be of two types:"The resources that are renewable rather than depleting them not use, like solar and wind.

"The non-renewable are those that exist in fixed amounts on Earth and take millions of years to regenerate as fossil fuels.

The training of alive matter or biomass from the solar light is carried out by the process named photosynthesis thanks to which there take place big molecules of contained energetic high place (in the shape of chemical energy), whose cost of storage is void and, at first, without losses.

FROM BIOMASS 

Biomass is any organic material from plants or animals. In domestic biomass resources are derived from agricultural and forestry residues, municipal solid wastes, industrial wastes, and terrestrial and aquatic crops grown solely for energy purposes

WHAT IS IT?

Forestry:

Forestry wastes.

Industrial waste (furniture, joinery, etc.).

Energy crops (thistles, poplars, etc.).

Agriculture:

Agricultural crop residues (thistles, straw, etc.).

Industrial wastes (almond shells, pine cones, bone oil, etc.)

Pellet:The feed pellet shaped and is made of pressed sawdust. The pellet must not contain any additives as these can damage the boiler.
