Is Finned Coil Heat Exchanger used for Flue Gas Denitrification?

Finned coil heat exchanger can be used for flue gas denitrification, mainly in the following aspects:

-Preheating the exhaust gas: in selective catalytic reduction (SCR) systems, it can be used as a component of the exhaust gas preheater. Because the denitrification catalyst usually needs to be in a certain temperature range to play the best activity, the finned coil heat exchanger can heat the tail gas to the appropriate temperature, thus improving the activity of the denitrification catalyst and removing the nitrogen oxides in the tail gas more effectively.

-Waste heat recovery: In the process of flue gas denitrification, the high temperature flue gas contains a large amount of waste heat. The finned coil heat exchanger can recover this part of the waste heat and use it to preheat the air, water or other media entering the denitrification system, which improves the energy utilization efficiency of the whole system and reduces the energy consumption and operation cost. At the same time, through the waste heat recovery to reduce the flue gas temperature, but also conducive to the stable operation of the subsequent denitrification equipment, to avoid equipment due to high temperature material aging, performance degradation and other issues.

The application of finned coil heat exchanger in flue gas denitrification helps to improve the denitrification efficiency, reduce energy consumption and ensure the stable operation of the equipment, which is an important auxiliary equipment in the flue gas denitrification system.
