Abstract:
Reactive nitrogen (Nr) raises big concerns particularly in form of Nitrogen Oxide (NOx) since it causes direct and indirect (as precursor) harm to society and environment. Also for the thermal use of biomass there have been intensive debates, but no study so far has quantified the impact of Nitrogen. Therefore a better understanding of how nitrogen performs along the biomass combustion cycle (i.e. from tree to emission) should be gained. Based on a literature study and own data we investigated the impact of small scale biomass combustion on the anthropogenous N-cycle. Our results show that only 50 % of nitrogen contained in fuel wood (i.e. spruce) are emitted as NOx into the atmosphere, the other 50 % are released as harmless N2. Furthermore our model shows that trees take up 50 % more N out of the atmosphere than what is emitted during combustion.
