Hanwha Power’s auxiliary upgrades increase the performance, flexibility, and environmental efficiency of gas turbine plants. These systems are designed to complement Hanwha Power’s combustion technologies (FlameSheet, LEC III, GTOP) and can also be installed independently on turbines with OEM combustion systems. Each upgrade integrates with existing plant controls and can be installed without major equipment overhauls.
Wet Compression Systems
Increase Power Output When It Matters Most
Wet compression is an advanced solution for boosting gas turbine output during high-demand periods. By cooling the inlet air and increasing mass flow through the compressor, wet compression enables more power to reach the generator. This results in improved turbine performance, especially during peak grid demand.
Hanwha Power’s system integrates directly with the turbine’s DCS and controls, offering operators a seamless interface with real-time monitoring and automated operation. The outcome: increased top-end capacity, lower emissions, and better fuel efficiency.
Inlet Bleed Heat / Anti-Icing System (IBH)
Protect Turbines While Expanding Operating Range
Hanwha Power’s IBH system addresses the risk of ice or snow buildup on inlet filters and compressor blades, which can cause mechanical damage and reduce efficiency. By introducing heated air upstream of the filters, the system prevents freezing conditions and extends the safe, low-load operational range.
Additional benefits include:
- Greater emissions compliance at lower load levels
- Protection of filters and compressor components
- Built-in alarms for ice formation detection
- Enhanced turndown flexibility and start reliability in cold climates

Exhaust Bleed Systems (ExB)
Extend Turndown. Stay Online Longer.
Hanwha Power’s Exhaust Bleed System takes flexibility further by enabling ultra-low load operation. By bleeding air from the exhaust side of the compressor, the turbine workload is reduced, allowing the unit to stay online longer at lower loads.
This solution helps operators:
- Avoid unnecessary shutdowns
- Improve responsiveness during cycling events
- Reduce fuel use and emissions at minimum load
- Cut startup costs by keeping the unit warm and ready
When paired with FlameSheet and AutoTune, ExB extends turndown an additional 5-10% beyond IBH-only operation, enabling total turndown capability as deep as 25-30% of baseload on7F platforms.
Why It Matters
Auxiliary upgrades like IBH, ExB, and wet compression are cost-effective pathways to improve performance and environmental compliance. With these solutions, your gas turbine plant can adapt to changing grid demands, reduce emissions, and optimize asset value, today and in the future.
Auxiliary Upgrade FAQs
Wet compression is a gas turbine power augmentationtechnology that cools inlet air and increases mass flow through the compressorby injecting atomized water upstream of the compressor inlet. This increasespower output during high-demand periods, improves fuel efficiency, and reducesemissions. Hanwha Power’s wet compression system integrates with the turbine’sDCS and controls for automated operation with real-time monitoring.
