For gas turbine intake, compressors, combined cycle power plants, offshore platforms and distributed energy stations, Yiran® provides multi-stage intake filtration systems from mist elimination pre-separation to HEPA fine filtration, effectively preventing blade erosion, salt spray corrosion and particle deposition, ensuring stable turbine output and long-cycle reliable operation.
Heavy-duty gas turbines ingest hundreds of cubic meters of air per second. Even micron-level particles cause erosion and deposition on compressor blades in high-temperature, high-velocity gas streams, reducing efficiency and increasing maintenance costs. The intake filtration system is the first line of defense for long-cycle safe turbine operation.
GT compressor blades rotate at subsonic/supersonic speeds. Even 0.5-5μm fine particles cause leading-edge erosion in high-temperature gas streams. Meanwhile, submicron particles and oily aerosols deposit on blade surfaces forming fouling layers that alter aerodynamic profiles, causing 3-5% compressor efficiency loss per 1000 operating hours and output reduction. OEMs like GE/Siemens require intake filtration efficiency ≥99.95% at 0.3μm.
Coastal power plants and offshore platforms face high salt spray challenges. NaCl particles decompose at combustion chamber temperatures producing chloride ions, reacting with fuel sulfur to form Na₂SO₄/NaCl eutectic molten salts causing Type I Hot Corrosion on blade superalloy coatings at 800-950°C. Offshore platform intake salt concentration can reach 0.1-10mg/m³, far exceeding OEM recommended limits.
Every 25.4mmH₂O (~250Pa) increase in GT intake pressure drop reduces output by ~0.5% and increases heat rate by ~0.2%. For a 400MW F-class turbine, this means ~2MW output loss. Intake filtration systems must balance high filtration efficiency with low pressure drop, while scientifically determining replacement/cleaning timing as filters gradually load with dust.
Desert regions (sandstorms), tropical coasts (high temperature + humidity + salt spray), arctic regions (icing/snow blockage), industrial zones (high dust + VOCs) impose extreme demands on intake filtration. Filters must withstand extreme temperatures (-40 to +60°C), high humidity (100%RH) and rainwater ingress while maintaining structural integrity and filtration performance. Self-cleaning pulse-jet system reliability in dusty environments is also critical.
Yiran® GT intake solution uses three-stage gradient filtration, from water droplet/coarse particle separation to submicron fine filtration, with self-cleaning pulse system for long-cycle maintenance-free operation.
