Firetube Boilers Engineered for Reliable, Efficient Steam Performance
O’Brien three-pass firetube steam boilers use a wet-back design with a large evaporation area to deliver reliable, high-quality steam from 2,000 to 22,000 kg/h at working pressures up to 12 bar. Robust and forgiving on water quality, they run a low-NOx flame and stay simple to service through an easily accessible furnace and tubes.
High thermal efficiency
Multi-pass waterside design maximises heat transfer, delivering efficiency ratings above 90% in continuous industrial operation.
Simplified maintenance
Removable tube bundles and accessible headers allow fast inspection and cleaning, minimising scheduled maintenance downtime.
Stable steam output
Advanced steam drum design and controls maintain consistent pressure and quality even under variable load conditions.
Long operational lifespan
Engineered for sustained high-pressure operation, firetube boilers provide decades of reliable service with proper maintenance.
