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 soda ash production enterprises using the ammonia-soda process, combined soda process, and natural soda process. It covers both light soda ash and heavy soda ash products. This standard is mandatory for all existing soda ash manufacturers and new construction projects in China. It references product quality requirements from GB/T 210.

技術要求

GB 29140-2024 establishes a 3-tier energy consumption limit grading system for soda ash, where Grade 1 represents the highest energy efficiency (lowest consumption). Existing facilities must comply with the Grade 3 limits, while new and expanded projects must meet the stricter Grade 2 requirements. The standard sets specific energy consumption thresholds differentiated by production methods (ammonia-soda, combined soda, natural soda) and product types (light soda ash vs. heavy soda ash). Energy consumption is measured in kilogram of standard coal equivalent (kgce) per ton of product.

試験方法

The standard outlines the statistical scope and calculation methods for comprehensive energy consumption. It includes all primary and secondary energy consumed from raw material processing to product warehousing, including safety and environmental protection measures. Various energy sources must be converted to standard coal equivalent using reference coefficients provided in the appendices, following the general rules of GB/T 2589. The calculation formulas separately address the comprehensive energy consumption for light and heavy soda ash production.

よくある質問

What products are regulated under GB 29140-2024?

It regulates light soda ash and heavy soda ash produced via the ammonia-soda process, combined soda process, and natural soda process.

What are the main updates in GB 29140-2024 compared to the 2012 version?

The 2024 version introduces a 3-tier energy consumption limit grading system, modifies the statistical scope and calculation methods, and removes the advanced value and energy-saving management sections found in the 2012 edition.

What are the energy consumption requirements for new soda ash production facilities?

New and expanded facilities must meet the Grade 2 energy consumption limits specified in the standard, which are stricter than the Grade 3 limits required for existing facilities.
