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:
Kind of fluid. |
| Dust content. |
| Maintenance and cleaning works. |
| Connection of the equipment with the rest of the plant. |
Depending on the above mentioned factors, different technical
solutions may be applied which will go through the adoption of an
arrangement: Vertical/Horizontal.
Modular (with only one or many fans).
One or more steps. |
