Production of heat from wood - Atmospheric emmissions - Assessment, impact and evolution

As we discussed in an earlier dossier [BE 8 750] , it would appear necessary to develop wood energy combustion while taking care to limit emissions of atmospheric pollutants. This requires the use of appropriate fuels and efficient techniques with high environmental performance. In other words, we need to develop and promote clean, sober biomass combustion.

Wood combustion has an impact on air pollution at both national and local levels (§ 1 and 2 ), both for domestic heating with independent appliances (open and closed hearths, stoves, stoves) and individual boilers, and for boiler rooms used to produce heat in the collective, tertiary and industrial sectors.

Domestic heating appliances are the most polluting per unit of wood consumed, and the most numerous in operation. Unlike industrial air treatment systems, which are more widespread in other sectors, reducing their emissions requires the development of specific expertise. Primary measures to prevent the formation of pollutants and secondary measures to treat the pollutants formed include :

• choice and use of equipment ;

• device design and sizing rules ;

• new pollution control systems ;

• the study of fuel and equipment variability;

• the requirements of standards...
