Abstract

Sposób ograniczania powstawania tlenków azotu oraz/lub ich redukcji polega na tym, że do komory paleniskowej w kierunku przeciwbieżnym do głównego kierunku, głównego strumienia spalin przepływającego przez komorę paleniskową, wtryskiwany jest gaz procesowy lub w kolejnej odmianie gaz procesowy z reagentem z prędkością od 30 do 180 m/s korzystnie 135 m/s, przy czym punkty wtrysku zlokalizowane są na przednim ekranie komory paleniskowej, na tylnym ekranie komory paleniskowej, na górnym ekranie komory paleniskowej oraz na bocznych ekranach komory paleniskowej. Układ do realizacji sposobu do redukcji NOx zawiera lance wtrysku gazu procesowego (6), (10), (12), (16), lance wtrysku reagenta (7), (13), (17), komorę paleniskową (4), czerpnię gazu procesowego (18), wentylator gazu procesowego (21), układ pomiarowy zabudowany na kolektorze gazu procesowego (22), elementy regulacyjno - odcinające zabudowane na kolektorze gazu procesowego (23), zbiornik reagenta (24), pompę reagenta (25), układy pomiarowe (26) zabudowane na instalacji reagenta, elementy regulacyjno - odcinające (27) zabudowane na instalacji reagenta, lancę centralnego wtrysku reagenta do gazu procesowego (28), urządzenie mierzące skład spalin (29) oraz urządzenie sterujące (30).The method of limiting the formation of nitrogen oxides and / or their reduction consists in injecting the process gas or, in a further variant, the process gas with the reactant at a speed of 30 to 180 m / s, preferably 135 m / s, the injection points being located on the front screen of the combustion chamber, on the rear screen of the combustion chamber, on the upper screen of the combustion chamber and on the side screens of the combustion chamber. The system for implementing the method for NOx reduction includes process gas injection lances (6), (10), (12), (16), reagent injection lances (7), (13), (17), a furnace chamber (4), an air intake process gas (18), process gas fan (21), measuring system installed on the process gas collector (22), control and shut-off elements installed on the process gas collector (23), reagent tank (24), reagent pump (25), measuring devices (26) installed in the reagent installation, control and shut-off elements (27) installed in the reagent installation, the lance of central reagent injection into the process gas (28), a device measuring the composition of exhaust gases (29) and a control device (30).
