基于采伐剩余物的生物质固体燃料生态效益分析
Eco-benefit Evaluation of Biomass Solid Fuel Based on Forest Cutting Residues
摘要
Abstract
The development of biomass solid fuel technology using forest cutting residues as raw materials can effectively relieve the waste of forest resources and energy shortage in China .The eco-benefit evaluation of forest residues biomass fuels , from collecting into available energy , was conducted using simplify LCA method and IPCC method .The results indicate that , carbon emission of the utilization of biomass solid fuels is 0.82 t/hm2 , carbon sequestration is 17.55 t/hm2 , net carbon is 16.73 t/hm2 , net carbon dioxide is 61.38 t/hm2 , which reflect carbon sequestration function . The most carbon emission is the processing stage , accounting for 68.97%of the total carbon emission , followed by the fuel use stage , accounting for 14.94%.The transportation stage is affected by the distance of transportation , accounting for 5.57%of the total carbon emissions of 20km of raw materials; the distance of finished products is 30 km and the carbon emission is 7.21%.The least carbon emission appeared at the artificial collecting , with only 3.31%.The energy efficiency is 0.032, and the conversion efficiency is high .From the point of view of ecological benefit , biomass solid fuel has great advantages .关键词
