【摘要】：与能源密切相关的污染问题及能源的日益短缺，已成为了制约我国社会经济可持续发展的两大难题。我国以煤炭为基础的能源结构决定了我国碳排放一直处于较高的水平。作为一个负责任的大国，我国政府承诺2020年单位GDP碳排放比降低40%-45%，同时也将该指标纳入社会发展和国民经济中长期发展规划。就钢铁企业层面而言，企业节能减排的政策压力越来越大，，这对企业自身的能源管理和能源效率评价提出了越来越高的要求。本文在我国钢铁行业和钢铁企业能耗和碳排放现状特点的基础上，总结了目前碳排放约束条件下我国钢铁企业综合能效评价的两大问题：在进行同区域跨行业能效评价时无法实现原材料能源消费等因素的综合考虑以及在碳排放约束条件下无法实现对企业碳排放的量化评价。针对这两个问题，本文提出了内涵能源强度‖和内涵CO2排放强度‖评价指标，建立了企业及行业评价指标估算模型，并结合T钢厂实际生产运营状况对T钢厂进行了综合能效及碳排放水平进行评价，最后提出了进一步节能和减少碳排放的相关建议。本文通过建立钢铁行业和钢铁企业的内涵能源强度及碳排放估算模型，实现了钢铁企业综合能效评价和碳排放的量化估算和评价的一种新的思路，并对其他流程性生产企业的综合能效及碳排放评价有着了较强的借鉴意义。
[Abstract]:The pollution problem closely related to energy and the increasing shortage of energy have become two major problems restricting the sustainable development of social economy in China. China's coal-based energy structure determines that China's carbon emissions have been in a high level. As a responsible big country, our government promises to reduce the carbon emission ratio per unit GDP by 40% to 45% in 2020, and at the same time, it will be included in the plan of social development and national economy development in the medium and long term. As far as iron and steel enterprises are concerned, the policy pressure of energy saving and emission reduction is increasing, which puts forward higher and higher requirements for energy management and energy efficiency evaluation of enterprises themselves. Based on the characteristics of energy consumption and carbon emission in China's iron and steel industry and iron and steel enterprises, This paper summarizes two major problems in the comprehensive energy efficiency evaluation of iron and steel enterprises in China under the current carbon emission constraints: the factors such as the inability to realize the energy consumption of raw materials in the same region and the comprehensive consideration of the carbon emission in the evaluation of energy efficiency of iron and steel enterprises in the same region are summarized. The quantitative evaluation of carbon emissions can not be realized under the constraint conditions. Aiming at these two problems, this paper puts forward the evaluation index of energy intensity and CO2 emission intensity, and establishes the evaluation index model of enterprise and industry. The comprehensive energy efficiency and carbon emission level of T steel plant are evaluated according to the actual production and operation situation of T steel plant. Finally, some suggestions on further energy saving and carbon emission reduction are put forward. In this paper, through the establishment of the intension energy intensity and carbon emission estimation model of iron and steel industry and iron and steel enterprises, a new idea of comprehensive energy efficiency evaluation and quantitative estimation and evaluation of carbon emissions in iron and steel enterprises is realized. And it has a strong reference significance for the comprehensive energy efficiency and carbon emission evaluation of other process production enterprises.
