Abstract
POSTUPAK ZA REDUKOVANO ISPUŠTANJE OKSIDA AZOTA KOD LOŽIŠTA NA UGLJENI PRAH, naznačen time, što se materijal koji sadrži ugljenik dovodi u vrtložni sloj (2) postavljen na izlazu (1) levka komore sagorevanja i sagoreva u vazduhu čija je količina ispod stehiometrijske; što se fine čestice izdvajaju u priključenom separatoru (3) pepela vrtložnog sloja (2) i vraćaju u vrtložni sloj (2) u kome se sagorevanje reguliše odvojeno od sagorevanja u ložištu (4) na ugljeni prah. Prijava sadrži još 3 zavisna zahteva.A PROCEDURE FOR REDUCED NOxES OF NITROGEN OXIDE BY COAL POWDER COAL, characterized in that the carbon containing material is introduced into the vortex (2) positioned at the outlet (1) of the combustion chamber funnel and burned in air below the stoichiometric amount; which separates the fine particles in the connected vortex ash separator (3) and returns to the vortex layer (2) in which the combustion is regulated separately from the combustion in the combustion chamber (4). The application contains 3 more dependent requests.
