Calculation method of carbon dioxide emission intensity from iron and steel production — Part 3: Steel plant with electric arc furnace (EAF) and coal-based or gas-based direct reduction iron (DRI) facility 钢铁生产二氧化碳排放强度计算方法第3部分:配备电弧炉（EAF）和煤基或气基直接还原铁（DRI）设施的钢铁厂

发布日期： 2024-09-16

                本文件规定了适用于使用电弧炉（EAF）生产钢铁并在其场所内拥有直接还原铁（DRI）设施的制造商的计算方法。
本文件允许用户涵盖现场铁矿石结块的特殊情况。可用于评价钢铁生产全过程二氧化碳（CO2）年排放总量和CO2强度的排放因子。本文件适用于主要生产碳钢的工厂。
它包括边界定义、物质和能量流定义以及CO2的排放因子。除了直接源输入到边界，上游和信用概念被应用于展示工厂的CO2强度。
本文件支持钢铁生产商确定某个地点的二氧化碳排放量。
可使用附件A获得能源消耗和消耗效率的换算。

This document specifies calculation methods applicable to manufacturers using an electric arc furnace (EAF) to produce steel and having direct reduced iron (DRI) facilities within their premises. 
This document allows the user to cover those particular cases of agglomeration of iron ore on site. It can be used to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of CO2 intensity of the entire steel production process. This document is applicable to plants producing mainly carbon steel.
It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides direct source import to the boundary, upstream and credit concept is applied to exhibit the plant CO2 intensity.
This document supports the steel producer to establish CO2 emissions attributable to a site.
Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
