【摘要】：煤炭作为我国的第一能源,其燃烧所带来的碳排放占全国总碳排放的比例一直都居高不下。煤炭行业在未来的若干年仍将是我国主要的经济支柱,因此运用何种方法来核算煤炭行业碳排放量,从而能够有效的降低能源消耗、减少碳排放,对于我国发展绿色产业、低碳经济事业有重要的推动作用。论文以永煤集团永城矿区为研究背景,以煤-电供应链为研究主线,通过生命周期分析方法的应用将煤-电供应链划分为四个主要环节,即煤炭开采、煤炭洗选加工、煤炭运输和燃煤发电环节,对这四个环节的生产活动进行研究和分析,确定各个环节的碳排放边界及存在的碳排放源,进而建立各环节兼具实用性和适用性的碳排放核算模型。根据矿区特征建立核算模型后,对各排放因子进行了合理的修正,进而对矿区煤-电供应链中各环节的碳排放量进行分别核算,并对核算结果进行分析,找出碳排量较大的生产环节,提出针对永城矿区有效的减排措施,包括推广低浓度瓦斯发电技术,完善用电机制,采用先进技术提高燃煤利用率等。鉴于煤-电供应链中碳排放核算过程的复杂性,本着简化碳排放核算过程,直观反映企业碳排放过程中问题的根源的目的,论文开发了应用于煤-电供应链的碳排放核算软件,该软件的应用能够有效的简化碳排放核算流程,提高核算效率和准确性,并设计了核算结果数据分析程序,通过分析找出企业降低碳排放最有效的途径。
[Abstract]:Coal as first energy in China, which will lead to combustion of carbon emissions of the total carbon emissions have been high. The proportion of the coal industry in the coming years will be China's main economic pillars, so the use of the methods to calculate the carbon emissions from the coal industry, and can effectively reduce the energy consumption. To reduce the carbon emissions for China's development of green industry, low carbon economy industry has an important role. According to permanent coal group in Yongcheng coal mine as the research background, main research on coal - electricity supply chain, through the application of the method of life cycle analysis of coal - electricity supply chain is divided into four major parts, namely coal mining, coal processing, coal transportation and coal power generation, to the four links of the production activities of research and analysis, to determine all aspects of the carbon emission boundary and existing sources of carbon emissions, and the establishment of the ring Section with carbon accounting model of the practicality and applicability. According to the characteristics of the establishment of accounting model of mining area, the emission factor was reasonable modification of carbon emissions and the link to the mining area of coal and electricity in the supply chain were accounted for separately, and the calculation results were analyzed to find out the carbon emissions of large production and put forward effective measures to reduce emissions in Yongcheng mining area, including the promotion of low concentration gas power generation technology, improve the power mechanism, the use of advanced technology to improve the coal utilization rate. Because of the complexity of coal - electricity carbon emissions accounting process in the supply chain, with the simplified carbon accounting process, reflect the problems in the process of corporate carbon emissions the purpose of development applied to the coal - electricity supply chain carbon emissions accounting software, this software can simplify the carbon accounting process effectively, improve accounting efficiency and accuracy, and The analysis program of the results of accounting results is taken to find out the most effective ways to reduce carbon emissions by enterprises.
