Pas mal de recherches sont actuellement entreprises à ce sujet, il faut dire que pendant longtemps, on se fichait un peu (j’exagère) de comment brûlait une bûche de bois ! Maintenant c’est différent…

Puis il y a aussi des nouvelles formes de bois qui arrivent, les pellets, les gros pellets, etc etc…

Les même émissions sont elles produites dans les chaudières à bois nouvelle génération, sensées produire une combustion plus complète de matériau ?

Ainsi le bois en brûlant émet 10 fois plus de dioxines qu’un moteur Diesel sans FAP (les emissions d’un moteur Diesel avec FAP sont jugées négligeables).
http://fr.wikipedia.org/wiki/Dioxine
Cette production est de 10 à 100 fois plus importante dans les chaudières bois (on parle de bois propre et non de recyclat de bois) comparée à une chaudière mazout ou gaz naturel.

Si cela vous intéresse je vous recommande la lecture d’un site québecois traitant du chauffage au bois: http://www.mddep.gouv.qc.ca/air/chauf-bois/index.htm
