General Introduction of Product
|Before designing this kind of equipment, it is necessary to know the nature of the gases to be cooled and their dust content.|
|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.|
|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.|
(a)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%.
(b)Since historically most combustion processes have not condensed the fuel, usual efficiency calculations assume the combustion products are not condensed.
(c)This assumption is implicit when basing calculations on the Lower Heating Value.
(d)A more rigorous approach would be to base efficiency calculations on the Higher Heating Value, which typically results in efficiencies less than 100%.
(e)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).
To sum up, the following items have to be taken into account when designing a flue-gases cooler:
|1||Kind of fluid.|
|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|
|7||Modular (with only one or many fans).
