Abstract
An exhaust gas discharging apparatus for connection to an exhaust gas fan including an exhaust gas nozzle comprising a duct device forming at least one exhaust passage that extends between first and second open ends. The duct device has at least one exterior duct wall forming at least two longitudinally extending bent wall portions that are distributed evenly about the periphery of the duct device with each bent wall portion sloping towards the longitudinal axis in the region of the second end. An annular cap or wind band is connected to the duct device and is disposed about and spaced apart from the second end of the duct device. The cap has a cap inlet located below the second end and outside the duct device and a cap outlet located outwardly from the second end in the longitudinal direction. Vertically extending wind deflecting panels are mounted on the duct device and extend horizontally outwardly and these panels extend vertically below the cap. The panels can be flat or curved as seen in horizontal cross-section.
