Heat recovery systems for flue gas in the Beverage industry

Corrosion and fouling problems limit heat recovery in breweries, distilleries and soft drinks plants. We design and deliver a robust heat recovery system for your plant so you can recover more heat.

Achieve sustainability goals

Prevent Corrosion & Fouling

Reduce CO2 emissions

Your boiler is losing up to 15% of its energy via the stack

What's keeping you from recovering this energy?


It is complex to determine the best way to lower your energy consumption.

Corrosive or fouling flue gases

Your flue gas is potentially  corrosive or fouling.

Business case

The payback time of waste heat recovery options must be less than 5 years.

We design and deliver heat recovery systems for the Beverage industry to reduce their carbon footprint

Save up to 10% energy on your thermal process

Recover heat - that is now lost - from flue gas

Your steam boiler has waste heat recovery potential

Recover more heat on steam boilers

Your flue gas is corrosive when you burn biogas, oil or coal.  Recovery of additional heat below the acid dew point is however possible. The heat is used to preheat combustion air or water

The way our heat recovery system works

Capture waste heat

When hot flue gas leaves the stack, it still contains a significant amount of energy. Our heat recovery system captures this heat from steam or hot water boilers. 

Preheat combustion air or water

Combustion air, boiler feed water, make-up water, CIP water or building heating  are warmed up with the captured waste heat. This directly reduces the consumption of fossil fuels. 

Our heat recovery systems for Breweries, Distilleries and Soft Drinks plants

Polymer Air Preheater

Warm up combustion air by extracting heat from flue gas. 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 CIP water with waste heat from flue gases. The economiser is corrosion resistant and is easy to maintain and to clean.


4% boiler efficiency increase

Within the Together Towards ZERO program, Carlsberg strives to make their breweries more sustainable. One of the steps taken in their Ukraine brewery is using a biogas fired steam boiler. 

Due to the usage of biogas, high concentrations of sulphur elements can be found in the flue gas. If the flue gas is cooled down, these sulphur components condense and form sulphuric acid which is very corrosive. To prevent this from happening, Carlsberg operated their system such that the flue gas was at a high temperature (>140 °C) leaving the stack. Additional heat present in the flue gas was not used.

HeatMatrix installed  a Polymer Air PreHeater which allowed Carlsberg to cool to temperatures below the acid dew point and achieve additional heat recovery on their steam boiler. There are no corrosion issues because of the corrosion resistance of  the polymer used in the HeatMatrix APH. Based on the success in Ukraine, Carlsberg Serbia introduced the same solutiton on their biogas fired boiler.

HeatMatrix will design, deliver and, upon request, install a complete heat recovery system on your site, so you don’t have to worry about the implementation.


The thermal efficiency is the precentage of the combustion energy (Lower Heating Value) that is effectively converted to steam. The remainder of the heat is lost via the stack. The efficiency of a steam boiler lies in the range of 85 - 95%. By installing an economiser or an air preheater, the loss of heat in the flue gas is reduced and thereby the boiler efficiency is improved and CO2 emissions are reduced.

Sulphur in fuels like natural gas, biogas, biomass, coal or fuel oil gets combusted and forms SOx. Most of this is in the form of SO2 and 2% to 4% is present as SO3. This SO3 condenses when flue gas is cooled and forms sulphuric acid (H2SO4). This leads to corrosion of metal surfaces, ducts and stacks. This condensation reaction takes place when the flue gas temperature drops below, or the flue gas comes in contact with a surface temperature below what is called the Acid Dew Point. The polymer heat exchange technology allows flue gas to be cooled without having the risk of corrosion.

Making your boiler more efficient reduces its fuel consumption and therefor lowers fuel costs. 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.
