Область применения
This standard applies to the calculation, assessment, and control of energy consumption per unit production for coal-based activated carbon and semi-coke manufacturing enterprises. It is mandatory for all existing, new, and renovated production facilities. The standard specifically excludes coal water slurry (CWS) products, which were covered in previous versions.
Технические требования
The standard establishes a three-tier energy consumption limit system for both coal-based activated carbon and semi-coke, where Tier 1 represents the lowest energy consumption. Existing facilities must comply with the Tier 3 limits, while new, renovated, or expanded facilities must meet the stricter Tier 2 requirements. For coal-based activated carbon, the standard provides separate energy consumption limits based on product types, including columnar activated carbon, briquetted activated carbon, raw coal crushed activated carbon, and activated coke. It also introduces an alternative calculation method where raw material energy consumption is included in the total energy metrics, as detailed in Appendix A. For semi-coke production, the standard specifies energy consumption limits and introduces a correction value based on the yield of semi-coke. Manufacturers must calculate their specific correction values to accurately assess their compliance status.
Методы испытаний
The standard outlines specific statistical scopes and calculation formulas for energy consumption. For coal-based activated carbon, the calculation involves dividing total energy consumption by the standard product output, utilizing conversion coefficients based on CCl4 adsorption rate or iodine adsorption value as specified in Appendix B. For semi-coke, the calculation incorporates a correction value based on product yield, detailed in Appendix C. Energy conversion to standard coal must follow the coefficients provided in Appendices D and E.
Частые вопросы
What products are regulated under GB 29995-2024?
The standard regulates coal-based activated carbon (including columnar, briquetted, crushed, and activated coke) and semi-coke. It no longer covers coal water slurry, which was removed from the previous version.
What are the compliance requirements for new facilities?
New, renovated, or expanded production facilities must meet the Tier 2 energy consumption limits. Existing facilities are required to comply with the less stringent Tier 3 limits.
How is raw material energy consumption treated in this standard?
By default, raw material energy (such as raw coal and tar) is excluded from the energy consumption statistics for coal-based activated carbon. However, the standard includes an alternative method in Appendix A for calculating limits when raw material energy is included.
