Maintenance friendliness is not the only goal we have focused on.
The new design is highly resistant to heat, abrasion, and acid, depending on the selected materials.
Since the cooling circuit is shielded from the flue gas, the heat and therefore energy transfer to the cooling air is technically significant.
The cooling air can be further utilised, thereby increasing the efficiency of a new or existing plant.
The cooler is designed as an air-to-air cooler.
In the design, the flue gas side and the cooling air side are considered independent systems.
One system, the flue gas side, must be resistant to heat, abrasion, and corrosion, and the other, the clean cooling air side, must withstand sometimes enormous temperatures, depending on the plant's design.
Wear Parts
We have constructively addressed the thermal and mechanical issues that occur on the cooling air side.
Of course, the flue gas pipes are still exposed to high stresses, and their lifespan can be increased by using special steels, but traditionally, they are nothing more than wear parts.https://jumboblock.app/arguments
Considering this problem, it is essential to create an easy maintenance option, which we have implemented in our cooler.
The entire rear chamber section can be easily removed, and the tube bundles can be just as easily replaced on their sliding frame.
This significantly reduces downtime and minimises maintenance costs.
The temperature ranges for the flue gas side vary between 850 - 1200 °C depending on the design of the upstream plant, and the cooling air side ranges between 300 - 650 °C.
Deviations are, of course, possible depending on the individual design of each plant.
Advantages
- Easy to maintain.
- Long heat resistance.
- Long resistance to acids.
- Long resistance to abrasion.
- Heat recovery through clean cooling air possible.
- No material attack on the secondary air cooling circuit by aggressive media.
- Long service life.
Design Options
Depending on the required flue gas volume, the cooling system can be designed as a single, double, or triple cooling system.
This means that the flue gases are divided into one, two, or three systems.
Depending on the required cooling air capacity, the system is cooled by one or more fans.
This ensures that the system remains easy to maintain.
