Patented Air/Air cooler for an easy and quick change of the tube bundles.


Flue gas cooler


Easy to maintain is not the only target what we had focused on

The new design is long resistant against heat, abration and acids which is naturally dependent on selected materials.

Since the cooling circuit is shielded from the flue gas and the heat and thus energy transfer to the cooling air is due to the engineering enormous.

The cooling air can be used further and thus the efficiency of a new or old plant can be increased. 


The cooler is designed as an air/air cooler

In the design, the flue gas and cooling air side are considered as independent systems.

One system, the flue gas side, must be resistant to heat, abrasion and corrosion and the other, the clean cooling air side, to sometimes enormous temperatures, depending on the design of the plant. 


Wearing parts

We have constructively implemented the thermal, mechanical problems that arise on the cooling air side.

Of course, the flue gas pipes are still exposed to a great deal of stress and their durability can be increased by using special steels, but they are still nothing more than wearing parts from a classical point of view. 

If you take this problem into account, then you inevitably have to create a simple maintenance option, which we have implemented in our cooler.

The entire rear chamber part can be easily removed and the tube bundles can be replaced just as easily on their sliding frame.

This significantly reduces downtime and keeps maintenance costs to a minimum.

The temperature ranges for the flue gas side are, depending on the design of the upstream plant, between 850 - 1200 °C and the cooling air side between 300 - 650 °C. 

Deviations are of course possible depending on the individual design of each plant.


Advantages of the new and patented cooler design

Easy to maintain.

Long resistant against heat.

Long resistant against acids.

Long resistant against abration.

Heat recovery via clean cooling air possible.

No material attack of the secondary air cooling circuit by aggressive media.

Long service life.


Exhaust gas cooler


Execution possibilities

Depending on the required flue gas quantity, the cooling system can be designed as single, double or triple cooling system. 

This means that the flue gases are split into one, two or three systems.

The system will be cooled by one or more fans, depending on the required cooling air capacity.

This maintains the ease of maintenance.
