Heat recovery systems for flue gas or exhaust air in Paper & Pulp Mills
Corrosion and fouling problems limit the recovery of more heat. With polymer heat exchangers you can recover additional heat and overcome these issues.

Availability of a robust solution
Finding a technically feasible solution to recover and reuse waste heat is a challenge.
Corrosive and fouling flue gases
When burning biogas from anaerobic waste water treatment or biomass, the flue gases are corrosive and fouling.
We design and deliver heat recovery systems for Paper & Pulp Mills to reduce their carbon footprint

Recover more heat on dryers
Recover more heat on steam boilers
Recover flue gas heat to warm up water or preheat combustion air. Make your steam boilers up to 10% more efficient.
The way our heat recovery system works
Capture waste heat
When hot flue gas and exhaust air leave the stack, they still contain a significant amount of energy. Our heat recovery system captures this heat from dryers and steam boilers.
Preheat drying air, combustion air or water
Drying air, combustion air, process water, make-up water or boiler feed water are heated with the captured waste heat. This directly reduces the consumption of fossil fuels.
Our heat recovery systems for Paper & Pulp Mills
Polymer Air Preheater
Warm up combustion air or drying air by extracting heat from flue gas or exhaust air. The air preheater is corrosion resistant, easy to maintain and to clean.
Stainless Steel or Polymer Economiser
Warm up boiler feed water, make-up water or process water with waste heat from flue gases or exhaust air. The economiser is corrosion resistant and is easy to maintain and to clean.
Case study: Paper mill Europe
6% efficiency improvement
This paper manufacturer has the ambition to make their production processes more sustainable. Their steam boiler is being co-fired with biogas. Currently, heat recovery from the flue gas of this boiler is limited due to the potentially corrosive nature of the flue gas.
Conventional metal air preheaters are not suitable for deep cooling of the flue gas because the acids in the flue gas will condense. A case study was prepared for the combination of a metal and polymer air preheater system. With this system, flue gas will be cooled down through the acid dew point to preheat the combustion air.
Combustion air will be preheated from 25 to 179 °C. The polymer air preheater part in the installed combination will make sure that there are no corrosion issues.
Your path to lower CO2 emissions, energy consumption and costs
Heat exchanger design and Business Case
A proposal is made that shows all technical details and an economic assessment with payback time. You have everything you need for approval to start a feasibility study.
How do I save energy on my production site?
What causes corrosion problems of flue gas?
What is the business case for an investment in heat recovery systems?
Making your boiler or CHP more efficient reduces fuel consumption and therefore lowers fuel costs. In addition, by making the heat recovery resistant for corrosion enables you to use biogas, which will further increase your savings. Clients have improved their efficiency by 5 to 10% and achieved payback times on the project investment in the range of 3 to 5 years.
