The air filter BR110+EF4-50 is a filtering device specifically designed for the fire-resistant oil tank of steam turbines. It filters out particles and impurities in the air sucked in by the tank, thereby protecting the interior of the steam turbine from damage.

The air filter BR110 effectively captures and intercepts particles and impurities in the air through its efficient filtering materials, such as fine fiber layers or activated carbon. In this way, only clean air is sucked into the turbine, ensuring the cleanliness and normal operation inside the turbine.

The reason for installing air filters BR110+EF4-50 in the EH oil system of the steam turbine is to protect the oil system from impurities in the air. The following are the specific reasons:

• 1. Prevent pollutants from entering: Dust, metal shavings, fibers, and other particles in the air may be sucked into the fuel tank with the air. These impurities may contaminate the oil, leading to a decrease in oil quality and ultimately damaging the lubrication and control systems of the turbine.
• 2. Maintain oil cleanliness: EH oil is used as lubricating oil and control oil in steam turbines, and its cleanliness is crucial for the normal operation of equipment. Air filters can effectively filter out impurities in the air, keep the oil clean, and reduce the impact of pollutants in the oil on the system.
• 3. Extending equipment life: By keeping the oil clean, air filters can help extend the service life of steam turbines and their related components. Reduce equipment wear and malfunctions caused by oil contamination.
• 4. Ensure system performance: Clean oil can better transmit energy and signals, ensuring the accuracy and response speed of the turbine control system. This helps to maintain stable operation of the steam turbine and efficient energy conversion.
• 5. Reduce maintenance costs: By preventing oil contamination, it can reduce frequent oil replacement and repair work, which helps to reduce long-term maintenance and replacement costs.

Therefore, installing an air filter in the EH oil tank of the steam turbine is one of the important measures to ensure long-term stable operation of the equipment.
