北方地区生物质颗粒燃料全生命周期碳排放评价

Assessment of carbon emissions from biomass particulate fuel throughout its lifecycle in the northern region

分析了生物质固体颗粒燃料的全产业链和特性,根据产业链划分了生物质固体颗粒燃料的全生命周期碳排放边界,通过把全生命周期划分为种植阶段、生产阶段、运输阶段和使用阶段等4个阶段组成,主要的碳排放阶段为生产阶段和运输阶段,建立了碳排放计算模型,通过计算得到北方地区生物质固体颗粒燃料的平均碳排放为0.09 g CO_(2)/kg,只占其燃烧使用阶段碳排放的5.3%,从全生命周期来看,生物质固体颗粒燃料碳排放量很小,可看作是零碳能源。

The whole industry chain and characteristics of biomass solid particulate fuel are analyzed.According to the industry chain,the carbon emission boundary of the whole life cycle of biomass solid particulate fuel is divided.The whole life cycle is divided into four stages:planting stage,production stage,transportation stage and use stage.The main carbon emission stages are production stage and transportation stage.A carbon emission calculation model is established,it is calculated that the average carbon emission of biomass solid particulate fuel in northern China is 0.09 g CO_(2)/kg,accounting for only 5.3%of its carbon emission in the burning stage.From the perspective of the whole life cycle,the carbon emission of biomass solid particulate fuel is very small,which can be regarded as zero carbon energy.
