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 energy consumption calculation and assessment of rare earth smelting and processing products, including compounds, metals and alloys, phosphors, and polishing powders. It is not applicable to products from the comprehensive recovery process of rare earth waste. The regulation covers various production processes such as extraction and molten salt electrolysis.

技術要求

The standard establishes mandatory energy consumption limits for existing and new rare earth metallurgical enterprises. It categorizes products into single rare earth oxides, metals, alloys, and specific materials like fluorescent powders and polishing powders, setting distinct comprehensive energy consumption limits for each category. For existing facilities, the standard defines limiting values that must be met to continue operations. New enterprises must adhere to stricter access values to establish production lines. Additionally, the standard introduces advanced values to encourage higher energy efficiency and technological upgrades. The regulation also specifies the statistical scope and calculation methods for energy consumption. It details the conversion of various energy sources into standard coal equivalent (tce) and outlines principles for calculating indirect energy consumption and waste heat recovery. Furthermore, the standard mandates energy management systems within enterprises. Companies must establish energy-saving assessment systems and equip appropriate energy metering instruments in accordance with GB 17167.

試験方法

The standard outlines calculation methods rather than physical testing procedures. It involves calculating the unit energy consumption for working procedures and the comprehensive energy consumption per unit product. The methodology requires converting actual energy consumption into standard coal equivalent using specified conversion coefficients, while accounting for auxiliary energy consumption and waste heat utilization to ensure accurate assessment.

よくある質問

What products are regulated under GB 29435-2012?

The standard regulates rare earth smelting and processing products, including compounds, metals and alloys, phosphors, and polishing powders. It does not apply to products from rare earth waste recovery processes.

Are the energy consumption limits mandatory?

Yes, the energy consumption limits for existing enterprises (Clause 4.1) and new enterprises (Clause 4.2) are mandatory. Compliance is required for market access and continued operation in China.

How is comprehensive energy consumption calculated under this standard?

Comprehensive energy consumption is calculated by summing the direct process energy consumption and the allocated indirect auxiliary energy consumption. All energy types are converted to standard coal equivalent (tce) using the coefficients provided in the standard's appendices.
