Wet Compression: Beyond Evaporative Cooling
While standard fogging cools the intake air, MeeFog systems can also be configured for Wet Compression (also known as overspray or intercooling).
- How it works: Sub-10-micron droplets are sprayed directly into the compressor.
- Thermodynamic Effect: The droplets evaporate inside the compressor, creating an intercooling effect that reduces compressor work.
- Performance Gain: This process reduces compressor work and increases output by 5–15% beyond what can be accomplished with evaporative cooling alone.
Technical Specifications & System Design
The MeeFog system utilizes proprietary impaction-pin technology designed for high reliability and minimal risk of blade erosion.
- Operating Pressure: 2,000 psi (138 bar). This high pressure is required to produce “true fog” with sub-10-micron droplets.
- Droplet Size: <10 microns (Sauter Mean Diameter). Small droplets evaporate quickly, preventing fallout and pooling.
- Nozzle Material: 316 Stainless Steel with laser-drilled orifices and permanently aligned impaction pins.
- Expected Lifespan: 30+ years with proper water treatment.
- Filtration: Pump skids include 0.35-micron inlet filters and 10-micron discharge filters to protect the nozzle manifolds.
Support Services for Fogging Systems
Mee Industries offers on-site commissioning and startup services, along with post-installation support, including:
- Functional testing of pumps, VFDs, and control logic
- Nozzle flow verification and pattern validation
- Coordination with turbine OEM representatives (if required)
- Operator training and handover documentation
- Nozzle inspection and refurbishing (if required due to water quality issues)
- Pump skid routine maintenance
- Control system tuning for optimized performance
- Performance verification and reporting
Gas Turbine Compatibility & Fogging System References
Since 1994, MeeFog technology has been installed on over 1,200 systems representing over 90 GW of operating capacity. These projects demonstrate experience with all major gas turbine OEMs, including GE, Siemens, Mitsubishi, and Alstom, diverse operating environments, and power generation applications ranging from industrial cogeneration and offshore platforms to large combined-cycle power plants.
