Zusammenfassung:	The present invention relates to a chimney tray (3) for a column (1) for thermal treatment of fluid mixtures, comprising a collecting tray (4) and at least two chimneys (5-1, 5-2) spaced apart horizontally in the collecting tray (4), where each chimney (5-1, 5-2) forms a vertically aligned chimney body (6-1, 6-2) which forms a passage orifice (7-1, 7-2) through the collecting tray (4), and has a cover unit (8-1, 8-2) arranged spaced apart from the chimney body (6-1, 6-2), and where the cover unit (8-1, 8-2) covers the respective passage orifices (7-1, 7-2) in the vertical direction. The chimney tray (3) of the invention is characterized by a screen (9) which extends around the chimney body (6-1) of a first chimney (5-1), with the lower annular edge (14) of the screen (9) below the upper edge (13) of the chimney body (6-1) of the first chimney (5-1) and the upper annular edge (11) of the screen (9) above the lower outer edge (12) of the cover unit (8-1) of the first chimney (5-1) or adjoining the lower outer edge (12) of the cover unit (8-1) of the first chimney (5-1).
