BS ISO 14404-3:2017规定了适用于使用电弧的公司的计算方法 炼钢炉（EAF），在其厂房内有直接还原铁（DRI）设施。信息技术 可用于评估年总二氧化碳（CO2）排放量和CO2排放系数 单位钢材产量是整个钢材生产过程的重要组成部分。本文件适用于工厂 主要生产碳钢。它包括边界定义、物质流和能量流定义以及二氧化碳排放因子。此外 采用向边界、上游和信贷直接进口源的概念来展示工厂的CO2 强烈本文件支持钢铁生产商确定场地的二氧化碳排放量。这 该文件不能用于计算基准或比较二氧化碳生产强度 在现场内运行的流程。可使用附录A获得能源消耗和消耗效率的转换。 交叉引用:ISO 14064-1:2006 Ed 1购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS ISO 14404-3:2017 specifies calculation methods applicable to those companies using an electric arc furnace (EAF) to produce steel and having direct reduced iron (DRI) facilities within their premises. It can be used to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of CO2 per unit of steel production 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. This document cannot be used to calculate benchmarks or to compare CO2 intensities of production processes that are operated inside the site.Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.Cross References:ISO 14064-1:2006 Ed 1All current amendments available at time of purchase are included with the purchase of this document.
