Pulp & Paper
Heat Recovery
Black liquor recovery, paper machine exhaust heat capture, and boiler economisers.
Heat exchangers engineered for pulp and paper — recovering waste heat from recovery boilers, paper machines, and process steam systems. SS 304L construction across 250–3,500 kW with counterflow design for maximum efficiency.

Applications
Select an application to explore heat recovery solutions for your pulp and paper mill.
Recovery boilers in Kraft pulp mills discharge flue gases at 180–300°C after the economiser section — still carrying significant recoverable energy. Our ThermStack TSE economisers provide additional heat recovery stages, preheating boiler feedwater or process water. For larger installations, EcoTherm EST shell and tube exchangers handle 2,000–3,500 kW of flue gas heat recovery. SS 304L construction resists the corrosive particulates and condensates from black liquor combustion.
Corrosion Proof
SS 304L handles black liquor combustion products
Humidity Tolerant
Designed for saturated hood exhaust streams
Self-Cleaning
Condensate drainage prevents fouling buildup
Compact Install
Fits existing boiler houses and machine halls
Built for
Pulp & Paper
Key advantages for pulp and paper mill applications.
Mill-Grade Construction
SS 304L handles the corrosive conditions of recovery boiler flue gases, black liquor particulates, and process water chemistry.
Paper Machine Savings
EcoTherm EAA hood exhaust recovery reduces dryer section steam demand by 10–20% — one of the largest energy savings in papermaking.
Process Water Recovery
Recover low-grade heat from white water, effluent, and condensate streams — preheating fresh water and reducing thermal discharge.
Humidity Handling
Heat exchangers designed for saturated and high-humidity exhaust — common in paper machine hoods and pulp processing areas.
Compact Retrofit
Horizontal or vertical mounting fits existing boiler houses, machine halls, and process areas without major structural changes.
CO₂ Reduction
Up to 4,466 tonnes CO₂/year — supporting pulp and paper decarbonisation targets and environmental permitting requirements.
Recovers Heat
Across Your Mill
Corrosion-resistant design for paper mill environments — handles black liquor, white water, and process steam conditions.
Your Mill Runs on Heat.
Stop Losing It.
Pulp and paper manufacturing is one of the most energy-intensive industries. From digester blowdown to dryer exhaust, your mill exhausts enormous quantities of recoverable thermal energy. Our shell and tube heat exchangers capture this waste heat for feedwater preheating, white water heating, or process stream recovery — withstanding the corrosive conditions unique to paper mills.
Recover waste heat from black liquor, blowdown, and exhaust systems — reducing steam and fuel costs across the mill.
SS 304L/316L construction withstands the acidic, high-humidity conditions in pulp and paper mill environments.
Removable end covers and cleanable tube bundles for easy maintenance — minimising fouling-related efficiency losses.
