Inlet icing can occur on LM series turbines at temperatures less than 40˚F (4.4˚C) and humidity greater than 65%. Ice formation can lead to restrictions in the inlet system resulting in possible damage to package and turbine equipment.
Applicable Turbine Models
LM2500, LM6000, LMS100
- Anti-icing system prevents ice related internal damage to engine blades, reducing turbine downtime and repair times.
- Anti-Icing system controls are automated to run only when ice detected.
- Increased efficiencies and power outputs as shown in the graph to the right.
- Anti-icing prevents ice accumulation on inlet system components eliminating any inlet air flow restrictions.
- Anti-icing can be utilized for performance heating
- Increase Uptime
- Improve Maintainability
How it works
- Inlet icing can occur on LM series turbines at temperatures less than 40°F (4.4°C) and humidity greater than 65%.
- Turbine exhaust waste heat or compressor bleed air is used to heat the inlet air by 10-15˚F above ambient temperature, preventing icing.
The turbine exhaust waste heat recovery system is a skid placed alongside the turbine, consisting of:
- Pump system using a closed loop of glycol-water.
- Chilling coils.
- Air filter house.
- Heat Exchanger connected to the combustion inlet air Waste Heat Recovery Unit (WHRU)
Control logic allows system to be idle if icing is not present and to activate when icing is detected. There are 4 total states: idle, anti-icing, air-purge, and full purge.
