Air Filtech Completes Installation of Self-Cleaning Inlet Filtration System for LM6000 Gas Turbines at Ca Mau Power Plant
Air Filtech has completed the installation and handover of a self-cleaning Pulse-Jet inlet filtration system for 3 LM6000 gas turbine units at Ca Mau Gas Power Plant, raising the system’s total air handling capacity to 1.2 million m³/hour.
The Challenge
The project was carried out to address severe turbine fouling in the Mekong Delta region, where the ambient air contains a range of contaminants that affect turbine performance, including sea salt and moisture from the coastal environment, seasonal pollen and organic particles, and fine dust generated by industrial and agricultural activity.
The previous filtration system, using static bag filters, required replacement twice a year, resulting in high maintenance costs, turbine operating disruptions, and declining power generation efficiency due to rapidly rising pressure drop.
Air Filtech’s Solution
Air Filtech supplied a 3-stage gas turbine inlet filtration system:
Stage 1 — Coalescer Demister Pad: separates salt mist, water droplets, and moisture before air enters the main filter.
Stage 2 — Cartridge Filter F8: a high-efficiency filter with an integrated Pulse-Jet self-cleaning mechanism operating every 6 hours.
Stage 3 — ΔP Monitoring System: tracks pressure drop in real time, providing early warning when a cleaning cycle or maintenance is needed.
Results After 6 Months of Operation
Pressure drop has been kept stable below 200 Pa, compared with around 450 Pa at the end of the previous system’s operating cycle. The turbines are maintaining 99.1% of design output, up from 95.7% before the upgrade. The upgrade delivers estimated savings of about VND 4 billion per year from reduced fuel consumption and maintenance costs, along with improved operating stability and longer turbine maintenance intervals.
A Flagship Gas Turbine Project
This is the 5th project in which Air Filtech has deployed a gas filtration solution for large-scale gas turbine systems in Vietnam, reinforcing its capabilities in industrial and power-sector air filtration.
