The global guidelines to combat global warming and thus reduce CO2 emissions in the atmosphere favor the development of renewable energies.
In this sense the use of wood pellets for heating or energy production has been growing steadily since the 1990s.
Promill engaged in the development of equipment since the 1980s and have made many installations crowned of success.
Promill is recognized as a technical and technological leader in this field.
- Industrial wood pellets: The pellets manufactured are intended for the production of heat and / or electricity. They are used by regional boilers or by larger power plants.
- Domestic wood pellets: The pellets manufactured are intended for the production of heat in homes. They are burnt by stoves or boilers.
Benefits of Wood Pellets
- Allow to recycle wood chips and sawdust from wood industries (sawmills, furniture factories, etc.) generating revenue instead of waste
- One ton of wood pellets has the energy equivalency of 2.8 barrels of fuel oil
- Direct thermal conversion of 3 million tons of wood pellets displaces the equivalent of almost 8.5 million barrels of fuel oil
- Direct thermal conversion of pellets has an efficiency level of approximately 80%
- Pellet stoves have extremely low particulate emissions due to their high burn efficiency and the density of the fuel.
- Every ton of pellets used vs. oil reduces CO2 emissions by about 1.5 tons.
- Pellet distribution costs less than the cost of distributing wood chips.
- Wood pellets have a fossil energy ratio (net energy output/fossil energy used) of 12:1.
- No artificial chemicals are added to wood pellets but starch or corn flour is sometimes used to improve stability: the result is a high density fuel with low moisture contents, which is less bulky to transport and store
