Why does the power industry need high-pressure oilless air compressors
As a pillar industry of the national economy, the stability and safety of its equipment operation are crucial. Compressed air plays a key role in pneumatic control, valve actuation, pipeline purging and other aspects of power plants. Traditional oil-containing air compressors may cause equipment failures or affect the continuity of power production due to the risk of lubricating oil pollution. With the technological upgrading of the power industry and the improvement of environmental protection requirements, high-pressure oil-free air compressors have become the preferred solution for the industry due to their high efficiency, stability and non-pollution characteristics.
Why does the power industry need high-pressure oilless air compressors
Power production requires extremely high purity, pressure stability and reliability of compressed air. According to ISO 8573-1:2010, compressed air must meet Class 0 (oil content ≤0.01mg/m³, particulate matter ≤0.01μm). High-pressure oil-free air compressors use oil-free lubrication technology (such as ceramic coating or water lubrication) to ensure that compressed air is free of oil molecules and meet the strict requirements of the power industry for air sources.
In addition, high-pressure oil-free air compressors usually have German Tüv “0” oil-free certification and environmental management system certification (ISO 14001) to ensure long-term stability of the equipment in high temperature and high pressure environments. For example, Shanghai Granklin Group’s high-pressure oil-free air compressor adopts oil-free compression technology that meets international standards. The compressed air it outputs can be directly used in high-precision scenarios such as boiler soot blowing and pneumatic instrument driving, providing continuity for power production. Provide reliable guarantee.
Key points for selecting core parameters of the power industry
- Air purity level: Must meet ISO 8573-1:2010 Class 0 (oil content ≤0.01mg/m³, particulate matter ≤0.01μm).
- Exhaust pressure range: It needs to cover 0.8-1.6MPa to meet the needs of high-pressure pneumatic equipment.
- dew point control: The drying system needs to support dew points below-40℃ (PDP) to avoid equipment corrosion caused by water vapor condensation.
- explosion-proof certification: In scenarios involving flammable and explosive gases, equipment must comply with the ATEX explosion-proof directive (covered by EU CE certification).
- energy efficiency rating: Priority should be given to inverter models that meet ISO 50001 energy management system certification to reduce energy consumption per unit of gas production.
Potential risks of not using high-pressure oilless air compressors
- equipment failure: Lubricating oil residues may cause clogging or failure of pneumatic components, affecting the continuity of power production.
- compliance risk: Companies that fail to meet ISO 8573-1:2010 standards may face environmental penalties and even affect power generation licenses.
- Increase in operation and maintenance costs: Oiled air compressors need to be equipped with additional multi-stage filtration systems (activated carbon + catalytic oxidation + precision filtration), and the annual maintenance cost increases by 30%-50%.
Economic benefits brought by high-pressure oilless air compressors
- Operation and maintenance cost optimization: Eliminate maintenance costs for lubricant replacement and oil mist recovery systems, and reduce annual expenses by 25%-35%.
- improvement of production efficiency: The equipment can run continuously for more than 12000 hours to avoid unplanned downtime caused by oil pollution.
- Carbon reduction benefits: Oil-free technology reduces volatile organic compound (VOC) emissions by 90% and meets carbon tariff (CBAM) compliance requirements.
Application comparison of high-pressure oilless compressor vs oilless compressor in the electric power field
| comparative dimension | High-pressure oilless air compressor | oil-lubricated air compressor |
|---|---|---|
| air purity | Comply with ISO 8573-1 Class 0 | Equipment requiring post-processing (residual risk ≥0.01mg/m³) |
| discharge pressure upper limit | 1.6MPa (high-pressure model) | 1.0MPa (requires multi-stage compression) |
| pollution risk | Zero oil pollution (complies with ISO 8573-1 Class 0) | Residual risk ≥0.01mg/m³ |
| whole life cycle cost | Low (2.5 times longer maintenance cycle) | High (70% increase in corrosion repair frequency) |
summary
The power industry’s demand for high efficiency and purity of compressed air has promoted high-pressure oilless air compressors to become the core equipment for process upgrades. By strictly benchmarking the ISO 8573-1:2010 standard and the German Tüv “0” oil-free certification, companies can significantly reduce production risks and improve environmental compliance. Driven by carbon neutrality goals and global power upgrades, oil-free technology will continue to provide efficient and sustainable compressed air solutions for the power industry.
