Abstract
Προκειμένου να κρατήσουμε την εκπομπή οξειδίων του αζώτου κατά την καύση καρβουνόσκονης για ατμοπαραγωγούς κάτω από τις απαιτούμενες οριακές τιμές, προσάγεται ανθρακούχο υλικό σε μια στροβιλιζομένη στιβάδα διατεταγμένη εις την έξοδο της χοάνης του θαλάμου καύσεως, οι από τον ακολούθως συνδεδεμένο διαχωριστή στροβιλιζομένης στιβάδος διαχωρισμένοι λεπτομερισμένοι κόκκοι επαναπροσάγονται εις τη στροβιλιζομένη στιβάδα, και η καύσις εις την στροβιλιζομένη στιβάδα ρυθμίζεται χωριστά από την καύσιν της καρβουνόσκονης. ωIn order to keep the emission of nitrogen oxides during the combustion of pulverized coal for steam generators below the required limit values, carbonaceous material is fed into a fluidized bed arranged at the outlet of the combustion chamber hopper, the fine particles separated by the downstream fluidized bed separator are fed back in the fluidized bed, and the combustion in the fluidized bed is regulated separately from the combustion of the coal dust. oh
