What is the oil content of compressed air in thermal power plants?
Oil content control of compressed air systems in thermal power plants is a key link to ensure equipment operation safety and production efficiency. Its standards need to be comprehensively determined based on specific application scenarios and industry specifications:
1. Conventional oil content control range
After multi-stage filtration in traditional oil-containing compressed air systems, the oil content can usually be controlled below 0.1mg/m³, but this value may still fluctuate due to factors such as equipment aging and untimely replacement of filter elements. If compressed air directly contacts precision instruments or control valve banks, residual oil may cause sensor sensitivity to decrease or actuator stuck.
2. Gas requirements for key equipment
In coal-fired power plants, core equipment such as boiler soot blowing systems and pneumatic valve control units have stricter requirements on the oil content of compressed air and must meet the “no visible oil content” standard (that is, the oil content is less than 0.01mg/m³). If traditional oil-containing compressors are used in such scenarios, additional activated carbon adsorption devices or membrane separation equipment are required, which significantly increases system complexity and maintenance costs.
3. Advantages of oil-free solutions
Equipment using water-lubricated single screw compression technology replaces traditional lubricating oil with pure water medium to eliminate the risk of oil pollution from the source of compression. The oil content of its output gas can be stably maintained at the lower limit of the resolution of the detection instrument (usually ≤0.001mg/m³), fully meeting the gas demand of the precision control system of the thermal power plant, and at the same time avoiding equipment failure and downtime caused by oil accumulation. risk.
Application value of Glanklin water-lubricated single screw compressor
Relying on the precise meshing design of the single screw and the star wheel, and the natural cleaning characteristics of the water lubricating medium, it provides continuous and stable high-quality compressed air for thermal power plants. This technology eliminates the need for a complex oil system, greatly reducing the frequency of equipment maintenance and the cost of replacing consumables. At the same time, the water lubrication method has excellent cooling effect, which can extend the service life of core components of the compressor and provide efficient and reliable gas-power solutions for the energy industry.
