利用混合生命周期评估方法对木质成型颗粒的可持续性进行评价,结果表明:木质成型颗粒全生命周期的能耗为0.11MJ/MJ颗粒,其中直接能耗79%,间接能耗21%,所占比例最大的是颗粒生产阶段的电力投入和生产设施投入;颗粒全生命周期的温室气体(GHG)排放为215kg CO2-eq/t颗粒,颗粒生产电力消耗造成的排放最大,其次是颗粒燃烧直接排放;生物质成型颗粒具有良好的可持续性,能在节能减排中发挥重要作用。
The results showed that the energy consumption of wood molding particles was 0.11MJ / MJ, of which direct energy consumption was 79% and indirect energy consumption was 21% The largest proportion is the power input and production facilities input in the pellet production stage. The emission of greenhouse gases (GHG) in the pellet life cycle is 215kg CO2-eq / t pellet, the discharge caused by the pellet production electricity consumption is the largest, followed by the pellet combustion direct Emissions; Biomass-forming particles have good sustainability and can play an important role in energy conservation and emission reduction.
