Introduction
National Standard of the People's Republic of China GB/T 37389—2019 Guidelines for Energy Efficiency Assessment of Off-line Refining Processes
Background and Significance of the Standard
GB/T 37389—2019 was proposed by the China Iron and Steel Association to guide and standardize the energy efficiency assessment of off-line refining processes. The formulation of this standard fully considers the current technological development status and energy conservation and consumption reduction needs of the steel industry, and provides a scientific basis for improving the overall energy efficiency level of the industry.
Explanation of Core Terms
| Terms | Definition |
|---|---|
| Energy Efficiency Index (EEI) | Reflects the ratio of the actual energy consumption of the off-line refining process to the benchmark energy consumption, and is used to evaluate the energy efficiency level. |
| Benchmark energy consumption | The best energy efficiency performance indicator of the refining process outside the furnace under specific conditions. |
Comparison of energy efficiency assessment frameworks
The following is a comparison table of the main dimensions of energy efficiency assessment of the off-furnace refining process:
| Assessment dimensions | Benchmark energy consumption | Actual energy consumption | Energy efficiency index (EEI) |
|---|---|---|---|
| Process boundary division | Based on the complete process from molten steel input to output | On-site data collection and calculation results | EEI ≤1.0 is excellent |
| Energy consumption of key equipment | Standard values of each refining method | Actual measurement values of the enterprise | EEI >1.2 indicates inefficiency |
| Energy saving potential analysis | Comprehensive judgment based on objective and subjective factors | Improve energy efficiency through optimization measures | The smaller the EEI, the greater the potential |
Actual application case analysis
Take a steel company as an example. When implementing the energy efficiency evaluation of refining outside the furnace, the company first clarified the process boundaries to ensure the accuracy and completeness of data collection. By measuring and calculating the actual energy consumption of the LF furnace and RH-KTB equipment, and comparing and analyzing the benchmark energy consumption value, the energy efficiency index was finally obtained to be 1.05.
According to the standard, the energy efficiency level of the company was rated as Level 2, indicating that its energy efficiency level is above the industry average but still has room for improvement. By optimizing the LF furnace electrode adjustment technology and introducing mechanical vacuum pump technology, the company successfully reduced the energy efficiency index to 0.98 and raised the energy efficiency level to Level 1.
