コンプライアンス概要

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 and assessment of energy consumption for general Portland cement production enterprises, as well as energy consumption control for new, reconstructed, and expanded projects. It is specifically designed for facilities producing cement and cement clinker, including independent grinding stations that use purchased clinker. This standard is mandatory for all cement manufacturers operating in China. It does not apply to specialty or non-Portland cement products.

技術要求

The standard establishes a three-tier energy consumption limit system for cement and clinker production, where Tier 1 represents the highest energy efficiency level. It specifies comprehensive requirements for comprehensive energy consumption, comprehensive electricity consumption, and comprehensive fuel consumption per unit of product. For existing facilities, the Tier 3 limits are mandatory, while new, reconstructed, and expanded projects must meet the stricter Tier 2 requirements. The standard also includes specific provisions for cement preparation section electricity consumption. Additionally, it introduces correction factors for facilities located at altitudes above 1500 meters and provides adjustment calculations for products with clinker ratios differing from 75%. Enterprises utilizing co-processing or alternative fuels must separately account for these energy sources in their calculations.

試験方法

The standard outlines statistical scopes and calculation formulas for various energy consumption metrics. It references GB/T 213 and GB/T 30727 for solid fuel calorific value determination, and GB/T 384 for liquid fuels. Electricity consumption statistics must comply with GB/T 27977. Energy metering equipment must be configured according to GB 17167 and GB/T 35461. The calculations include specific formulas for clinker fuel consumption, electricity consumption, and comprehensive energy consumption, factoring in waste heat recovery power generation where applicable.

よくある質問

What products are regulated under GB 16780-2021?

GB 16780-2021 regulates the energy consumption of general Portland cement and cement clinker production. It applies to existing manufacturing facilities as well as new, reconstructed, and expanded projects.

What are the main updates in GB 16780-2021 compared to the 2012 version?

The 2021 version updates terminology related to energy consumption, introduces a three-tier energy consumption limit system, and moves the electricity consumption limits for the cement preparation section from an appendix to the main text. It also updates correction factors and calculation formulas.

Are there altitude or clinker ratio adjustments in GB 16780-2021?

Yes, the standard includes an altitude correction coefficient for facilities located above 1500 meters. It also specifies adjustments to the comprehensive energy consumption limits if the clinker ratio in the cement product deviates from the standard 75%.
