적용 범위

This standard applies to the calculation and assessment of unit product energy consumption for underground mined tungsten concentrate, open-pit mined molybdenum concentrate, and roasted molybdenum concentrate. It is also applicable for energy consumption control in new, reconstructed, and expanded projects within these specific mining and processing sectors. It does not apply to open-pit mined tungsten concentrate, underground mined molybdenum concentrate, or facilities producing these as by-products. This standard replaces GB 29145-2012, GB 29146-2012, and GB 31340-2014.

기술 요구 사항

The standard establishes a three-tier energy consumption limit system for the specified mineral products, where Tier 1 represents the lowest energy consumption. Existing production enterprises must comply with the Tier 3 limits, while new, reconstructed, or expanded projects must meet the stricter Tier 2 limits. The limits are categorized by specific production types, such as black tungsten, white tungsten, and various molybdenum processing methods like SABC and three-stage closed-circuit. To ensure comparability across the industry, the standard introduces the concept of comparable energy consumption per unit product. This involves adjusting the calculated energy consumption using a raw ore grade conversion factor to account for variations in ore quality. The standard also defines the specific production, auxiliary, and affiliated systems included in the statistical scope of energy consumption. The technical requirements specify the baseline product standards for calculating qualified product output, referencing YS/T 231 for tungsten concentrate, YS/T 235 for molybdenum concentrate, and GB/T 24482 for roasted molybdenum concentrate. Manufacturers must ensure their energy accounting aligns with these defined product quality benchmarks.

시험 방법

The evaluation of energy consumption involves comprehensive statistical accounting across production systems, auxiliary systems, and affiliated systems. The calculation method utilizes specific formulas to determine the unit product energy consumption by aggregating various energy sources, subtracting recovered secondary energy, and dividing by the qualified product output. For tungsten and molybdenum concentrates, a comparable energy consumption value is further calculated by applying the appropriate raw ore grade conversion factor based on the concentration ratio.

자주 묻는 질문

What products are regulated under GB 29145-2023?

The standard regulates the unit product energy consumption for tungsten concentrate (underground mining), molybdenum concentrate (open-pit mining), and roasted molybdenum concentrate.

What are the compliance limits for new projects under this standard?

New, reconstructed, or expanded projects must meet the Tier 2 energy consumption limits. Existing facilities are required to comply with the Tier 3 limits.

How does GB 29145-2023 address variations in ore quality?

The standard uses a raw ore grade conversion factor to calculate the comparable energy consumption per unit product, ensuring fair assessment across different ore grades. The conversion factors are provided in the normative appendix based on the concentration ratio.
