摘要
为解决工业过程碳排放降碳方法及标准不明确的问题,需要定量评价碳排放影响以制定科学的碳减排计划。传统的工业过程降碳改造局限于厂内的能源替代、设备改造等措施,因此提出一种用于描述产品全生命周期内对气候积极影响的碳手印方法,结合碳足迹构建了更加全面的评价体系。以某企业工业过程中制造的水轮发电机配套水发定子线圈为研究对象,考虑边界内外多种降碳改造方案,进行了边界划分、碳足迹核算和碳手印分析,计算不同方案所产生的效率增量、寿命增量及碳手印。结果显示替换绝缘材料方案效果最为显著,碳手印方法为案例企业的降碳改造提供了有效指导。
To address the ambiguity surrounding methods and standards for reducing carbon emissions in industrial processes,it is essential to quantitatively assess the impact of carbon emissions and formulate a scientifically grounded carbon reduction plan.Traditional approaches to carbon reduction in industrial processes are confined to measures such as energy substitution and equipment modification within the factory.Therefore,a carbon handprint method for describing the positive climate impact of products throughout their lifecycle is proposed.Based on the carbon footprint,the paper establishes a more comprehensive evaluation system.With the stator coils for hydroelectric generators manufactured in the industrial processes of a particular company as the research subject,various carbon reduction schemes both inside and outside the boundaries are considered.Boundary delineation,carbon footprint calculation,and carbon handprint analysis are conducted,and efficiency increments,lifespan increments,and carbon handprints generated from different schemes are calculated.The results show that the replacement of insulation materials has the most significant effect,and the carbon handprint method proves to be an effective guide for carbon reduction transformation in the case company.
