Abstract

UREDJAJ I POSTUPAK VRŠENJA KONTROLE NOx, poboljšani sistem (14) dodatnog vazduha kontrole NOx za korišćenje u sistemu (12) loženja tipa je posebno pogodan za korišćenje u peći (10) loženoj fosilnim gorivom. Postupak rada takve peći (10) u sebi sadrži poboljšani sistem (14) dodatnog vazduha. Poboljšani sistem (14) dodatnog vazduha za kontrolu NOx uključuje: kutiju (22) montiranu u peći (10) na fosilno gorivo, prvu mlaznicu (68) na fosilno gorivo poduprtu u kutiji (22) na njenom prvom nivou, sekundarnu vazdušnu mlaznicu (74) poduprtu u kutiji (22) na njenom drugom nivou, drugu mlaznicu (8) za fosilno gorivo poduprtu u kutiji (22) na njenom trećem nivou, više odeljaka (94, 96) dodatnog vazduha montiranih u peći (10) na fosilno gorivo iznad i na rastojanju od kutije (22), prvu mlaznicu (100) dodatnog vazduha poduprtu u jednom (94) od više odeljaka (94, 96) dodatnog vazduha, drugu mlaznicu (102) dodatnog vazduha poduprtu u drugom (96) od više odeljaka (94, 96) dodatnog vazduha, treću mlaznicu (88, 90) dodatnog vazduha poduprtu u kutiji (22) na njenom četvrtom nivou, i sredstvo (28) za dovod vazduha vezano sa mlaznicom (100) dodatnog vazduha, mlaznicom (102) dodatnog vazduha i mlaznicom (88, 90) dodatnog vazduha.
