<p>Το ecoDROPdenser στοχεύει στην ανάπτυξη υπερλεπτών υμενίων για τη βελτίωση της απόδοσης και την προστασία επιφανειών σε λέβητες συμπύκνωσης. Η χρήση της λανθάνουσας θερμότητας συμπύκνωσης αυξάνει σημαντικά την απόδοση των λεβήτων, αλλά προκαλεί προβλήματα λόγω του διαβρωτικού χαρακτήρα των συμπυκνωμάτων, κυρίως λόγω των SOx στα απαέρια τα οποία συμπυκνούμενα σχηματίζουν H2SO4. Οι επικαλύψεις που θα αναπτυχθούν (i) θα είναι υπερ-λεπτές και συνεπώς δεν θα μειώνεται σημαντικά ο συντελεστής θερμικής αγωγιμότητας, (ii) θα αποτίθενται από αέρια φάση και συνεπώς δεν θα δημιουργούνται υγρά απόβλητα, (iii) θα ενισχύουν τη συμπύκνωση σε σταγόνες και την απορροή των συμπυκωμάτων και συνεπώς θα έχουν αυξημένο συντελεστή μεταφοράς θερμότητας. Η λειτουργικότητα της καινοτόμου επικάλυψης θα αξιολογηθεί ενεργειακά σε εμπορικό λέβητα.</p> (Greek)

<p>The ecoDROPdenser aims to develop ultra-fine film to improve performance and protect surfaces in condensation boilers. The use of latent condensation heat significantly increases the yield of boilers, but causes problems due to the corrosive character of the concentrates, mainly due to SOx in flue gases which condensate to form H2SO4. The coatings to be developed (i) will be super thin and therefore will not significantly reduce the coefficient of thermal conductivity, (ii) deposited by gas phase and therefore no liquid waste will be generated, (iii) will enhance condensation in drops and the runoff of concentrates and thus have an increased coefficient of heat transfer. The functionality of the innovative coating will be energy-assessed in a commercial boiler.</p> (English)
