この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the calculation, assessment, and energy consumption control of carbon products and their main production processes. It specifically covers graphite electrodes (including regular power, high power, and ultra-high power), carbon electrodes, and carbon blocks (graphitic, semi-graphitic, and microporous). It is mandatory for existing facilities and new constructions in the carbon manufacturing industry. The standard also regulates the energy consumption of key manufacturing procedures, specifically the baking and graphitization processes.

技術要求

The standard establishes a three-tier energy consumption limit system for carbon products, where Tier 1 represents the most stringent efficiency level and Tier 3 represents the basic mandatory limit. It defines specific requirements for the comprehensive energy consumption per unit product and the electricity consumption during the graphitization process. For existing carbon enterprises, the energy consumption of graphite electrodes, carbon electrodes, and carbon blocks must not exceed the Tier 3 limits. Existing facilities must strictly comply with these baseline requirements to maintain operational compliance. For new or expanded production equipment and processes, the energy consumption access values must not exceed the Tier 2 limits. This ensures that new investments in the carbon industry meet higher energy efficiency standards. The standard also details the statistical scope of energy consumption, clarifying that comprehensive energy consumption includes all energy used in production systems, auxiliary systems, and management, while explicitly excluding energy used for domestic or living purposes. It references GB/T 12723 for general principles and provides specific calculation formulas for process and comprehensive energy metrics.

試験方法

The standard outlines specific calculation methods rather than physical testing procedures. It requires enterprises to calculate the unit product energy consumption for baking and graphitization procedures using a defined mathematical formula that incorporates actual energy consumption, standard coal conversion coefficients, and product yield. The comprehensive energy consumption for final carbon products is calculated by summing the energy consumption of all preceding processes, adjusted by their respective yield rates. Manufacturers must use the provided formulas and standard coal reference coefficients to accurately report their energy metrics. The standard includes an appendix with reference coefficients for various energy sources like raw coal, coke, and electricity, as well as an allocation coefficient table for different production procedures.

よくある質問

What products are regulated under GB 21370-2017?

GB 21370-2017 regulates the energy consumption of graphite electrodes (regular, high, and ultra-high power), carbon electrodes, and carbon blocks (graphitic, semi-graphitic, and microporous), as well as the baking and graphitization production processes.

Are there any updates from the previous version of GB 21370?

Yes, compared to GB 21370-2008, the 2017 version introduces a three-tier energy consumption limit system, removes advanced energy values and energy management measures, and revises the calculation formulas. The electricity consumption for the graphitization process is now specifically defined as the process electricity consumption of semi-finished graphitized products.

What are the energy consumption limits for new carbon manufacturing facilities?

For new or expanded facilities, the energy consumption access values must not exceed the Tier 2 limits specified in the standard's tables. This is stricter than the Tier 3 limits applied to existing facilities, ensuring new projects adopt better energy efficiency.
