Introduction
GB/T 34605—2017 Technical Requirements for Operational Evaluation of Coal-fired Flue Gas Desulfurization Equipment
1. Standard Overview
GB/T 34605—2017 Technical Requirements for Operational Evaluation of Coal-fired Flue Gas Desulfurization Equipment is a standard formulated by China for the operation evaluation of wet flue gas desulfurization equipment (such as limestone-gypsum desulfurization, ammonia desulfurization, seawater desulfurization, etc.) and dry/semi-dry desulfurization equipment for coal-fired power station boilers. This standard is applicable to various types of coal-fired flue gas desulfurization equipment, aiming to ensure that its environmental performance, resource and energy consumption, technical and economic performance, operation management and equipment status meet national and local requirements.
2. Comparison of standard frameworks
| Evaluation dimensions | Standard scores | Core indicators |
|---|---|---|
| Environmental performance | 50 points | S O2 emission concentration, desulfurization efficiency, mercury emission concentration, smoke (dust) emission concentration, SO3 emission concentration, etc. |
| Resource and energy consumption | 10 points | Unit desulfurization absorbent consumption, unit desulfurization water consumption, unit desulfurization comprehensive energy consumption. |
| Technical and economic performance | 20 points | Equipment availability, system resistance, load adaptability, by-product comprehensive utilization rate, unit sulfur dioxide removal cost, etc. |
| Operation management | 10 points | Integrity of operation records, test and analysis reports, personnel certification, inspection and maintenance records, etc. |
| Equipment status | 10 points | Equipment status of flue system, absorption tower system, absorbent preparation system, by-product treatment system, etc. |
3. Implementation Suggestions
Case Analysis: A coal-fired power plant uses limestone-gypsum desulfurization equipment and evaluates its effectiveness after 6 months of operation. According to the standard requirements:
- SO2 emission concentration must be ≤35 mg/m³ (key areas) or ≤100 mg/m³ (special areas in non-key areas).
- Desulfurization efficiency must be ≥98% (wet method) or ≥92% (dry method/semi-dry method).
- Unit desulfurization comprehensive energy consumption must be ≤86 kgce/tSO2 (Grade A).
Through the implementation of these technical requirements, the power plant successfully increased the equipment availability to 98% and achieved SO2 emission concentration compliance.
