Biomass boilers

Biomass boilers

A wood boiler consists primarily of five elements:

  • a storage silo;
  • a system of extractors and conveyers of wood pellets / chips to the fireplace;
  • the boiler consists of a fireplace and a heat exchanger with the network;
  • a flue gas cleaning system (dust collector);
  • an ash removal system.

These plants have a very high efficiency and usefullness :

  • Energetically, the efficiency of biomass boilers is excellent (90%).
  • Socially, wood projects create many jobs in the forestry industry and the supply chain (1 job for 1000 tons, or about two jobs per MW).
  • Environmentally, the wood is a renewable energy with no CO2 emission during the life cycle. Per KWh, wood is 2 to 5 times cheaper than photovoltaic energy, and 2 to 3 times cheaper than fuel oil.


Biomass is the largest source of renewable energy in Europe

Biomass alone accounts for 68.5 % of the renewable energy produced in EU-27, mainly in the form of solid wood biomass for heating :

Despite an already important role, wood as source of energy still has a significant growth potential as a means to fight climate change. It should be, according to the”Grenelle de l’Environnement”, the main contributor of renewable energy in France by 2020.
