When Sustainability and Efficiency Matter, Nothing Goes Up the Stack Unused.
- Up to 226,796 kg/h
- Up to 95% NOx Cut
- SCR + CO Catalyst
Waste heat recovery boilers capture energy from hot exhaust gases — from engines, turbines, kilns or process streams — and turn it into usable steam or hot water, cutting fuel use and carbon emissions. Each O’Brien unit is engineered around the available flue-gas temperature, flow and back-pressure of your process.

Capture and convert waste heat from exhaust streams, kilns, or turbines into usable steam — recovering up to 85% of otherwise wasted energy.

Utilising process waste heat as the primary energy source can reduce supplementary fuel demand by 30–60% in many applications.

Waste heat recovery reduces the need for combustion, directly lowering CO₂, NOx, and particulate emissions across your facility.

Designed to connect with existing furnaces, engines, gas turbines, and industrial processes with minimal structural modification.
