Abstract
Nasada zwłaszcza kominowa posiada dyfuzor (2) wykonany u wylotu z króćca (1) połączony ze stożkowym pierścieniem dolnym (3). Struga gazu szybko poruszająca się w pobliżu wewnętrznej powierzchni króćca (1) jest odchylana przez dyfuzor (2) i kierowana na zewnątrz nasady zwłaszcza kominowej. Odchylenie strugi gazu przez dyfuzor (2) zmniejsza opory przepływu gazu przez nasadę. Podczas poziomego wiatru przepływającego przez nasadę zwłaszcza kominową struga powietrza jest podnoszona przez stożkowy pierścień dolny (3) i odrywana na krawędzi w miejscu połączenia pierścienia dolnego (3) z dyfuzorem (2). Oderwanie strugi powietrza chroni przed kierowaniem strugi powietrza przez dyfuzor (2) do króćca (1) oraz zwiększa prędkość powietrza przepływającego nad wylotem z króćca (1) powodując wytworzenie podciśnienia na wylocie z króćca (1).Especially the chimney cap has a diffuser (2) made at the outlet from the stub pipe (1) connected to the conical bottom ring (3). The gas stream rapidly moving near the inner surface of the stub pipe (1) is deflected by the diffuser (2) and directed outside of the chimney cap. The deflection of the gas stream through the diffuser (2) reduces the gas flow resistance through the cap. During horizontal wind flowing through the chimney base, the air stream is raised by the conical bottom ring (3) and torn off at the edge where the bottom ring (3) connects with the diffuser (2). Separation of the air stream protects against directing the air stream through the diffuser (2) to the stub pipe (1) and increases the velocity of air flowing over the outlet from the stub pipe (1), creating a negative pressure at the outlet from the stub pipe (1).
