Flue gas waste heat recovery module with sonic or steam blower required standard of exhaust air emission
Product Description
1. 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.
2. 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 | Before designing this kind of equipment, it is necessary to know the nature of the gases to be cooled and their dust content. |
| 2 | The purpose of all that is to design an equipment free of important fouling which would force to make cleaning works more frequently than wanted. |
| 3 | We must have in mind as well the availability to detach the dust from the gaseous stream containing it in all those areas where there is a bend or some enlarging in the pass section, which forces to include in the design some systems for dust collection and removal, to allow the correct heat exchange. |
Conclusion
To sum up, the following items have to be taken into account when designing a flue-gases cooler:
| 1 | Kind of fluid. |
| 2 | Dust content. |
| 3 | Maintenance and cleaning works. |
| 4 | Connection of the equipment with the rest of the plant. |
| 5 | Depending on the above mentioned factors, different technical solutions may be applied which will go through the adoption of an arrangement |
| 6 | Vertical/Horizontal. |
| 7 | Modular (with only one or many fans). |
Efficiency
| 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%. |
| 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). |
