Abstract
Μέθοδος για την αποαζώτωση (Εntstickung) καυσαερίων εγκαταστάσεων καύσης εν συνεχεία προς την αποκονιοποίηση ή την αποθείωση τους, στην οποία τα προοριζόμενα για αποαζώτωση καυσαέρια επαναθερμαίνονται δια μεταφοράς θερμότητας από τα αποαζωτώμενα καυσαέρια σε ένα θερμοεναλλάκτη αναγέννησης. Τα προοριζόμενα να αποαζωτωθούν καυσαέρια πριν από τη τελική θέρμανση τους στο επίπεδο θερμοκρασίας της αναγωγικής αντίδρασης και τα αποαζωτωμένα καυσαέρια εν συνεχεία προς την αναγωγή τους σε ένα πρόσθετο καταλύτη, που χρησιμεύει σαν κύριος καταλύτης, οδηγούνται σε κυκλική εναλλαγή κατά αντίθετο ρεύμα μεταξύ τους μέσω θερμοεναλλασσουσών μαζών συσσωρευτών, των οποίων οι επιφάνειες είναι εφοδιασμένες με καταλυτικά αντιδρώσες ενώσεις. ω
