Long Lifetime Flue Gas Cooler for Drying or Cooling Usage for Various Equipments

Product Introduction

Working principle of a flue-gases cooler is the same as in the above-described equipment, but the aim in this case is to cool a primary fluid, not to get a thermal profit by heating a secondary fluid.These equipment are usually installed as the previous step to a flue-gases cleaning, to avoid the gases from reaching the cleaning systems at too high temperatures. This means an alternative to the dilution with air, which would imply an over-sizing of the mentioned systems.

Details

1. Flue gas condensation may cause the heat recovered to exceed the Lower Heating Value of the input fuel, and thus an efficiency greater than 100%.

2. Since historically most combustion processes have not condensed the fuel, usual efficiency calculations assume the combustion products are not condensed.

3. This assumption is implicit when basing calculations on the Lower Heating Value.

4. A more rigorous approach would be to base efficiency calculations on the Higher Heating Value, which typically results in efficiencies less than 100%.[citation needed]

5. Should the flue gases be cooled below 25 °C (77 °F), even efficiencies based on the Higher Heating Value may exceed 100%, since typical heating value definitions assume that all heat is released when combustion products are cooled to somewhere between 15.56 °C (60.01 °F) and 25 °C (77 °F).

Attention

The following items have to be taken into account when designing a flue-gases cooler:
