在这项工作中，木材加热链的环境和微观经济方面进行了评估。木材燃烧产生各种次要污染物，应在生命周期评估中予以考虑。为此，在白杨Plus（R）软件下对不同的木材燃烧过程进行建模，以评估污染物排放（CO2、芳香化合物、CO等）。根据工业排放数据，从而获得严格的生命周期清单。不同的技术被评估为一个固定的供暖需求和热水生产的一个典型的法国房子：区域供暖燃料的木屑，个人炉灶或锅炉燃料的原木或颗粒。电力、天然气和燃油解决方案完成了场景集。在温室气体排放和最终能源成本（包括投资和运营成本）方面比较了不同的加热解决方案。次要污染物（如CO和挥发性有机化合物）对木材到热量链的全球升温潜能值的重要影响得到了强调。与基于化石的情景相比，木材情景的表现也高度依赖于为生物源CO2假设的影响因子。基于木材的方案存在广泛的成本，颗粒解决方案在投资和颗粒生产方面更加昂贵。
In this work wood-to-heat chains are assessed on environmental and micro-economical aspects. Wood combustion produced various minor pollutants, which should be considered in life cycle assessment For this purpose different wood combustion processes have been modeled under Aspen Plus (R) software in order to assess pollutant emissions (CO2, aromatic compounds, CO, etc.) based on industrial emission data and therefore to obtain a rigorous life cycle inventory. Different technologies are assessed for a fixed heating demand and hot water production of a typical French house: district heating fueled by wood chips, individual stoves or boilers fueled by wood logs or pellets. Electricity, natural gas, and fuel oil solutions complete the scenario set. The different heating solutions are compared in terms of their greenhouse gas emissions and of the cost of the final energy (including investment and operating costs). The important effect of minor pollutants (such as CO and volatile organic compounds) on the global warming potential of wood-to-heat chains is highlighted. The performance of wood scenarios compared to fossil-based ones is also highly dependent on the impact factor assumed for the biogenic CO2. The wood-based scenarios present a wide range of costs with pellet solutions being more expensive on investment and pellet production.
