Abstract (en)
[origin: EP0304909A2] A chimney cowl with a cantilever plate (4) which is fastened under the upper end of the smoke pipe (1) and of the casing (2) enclosing the smoke pipe (1), a wall surround (5) which is supported on the cantilever plate (4) and surrounds the casing (2), and a cover plate (10) which rests on the wall surround (5) and has an opening for passage of the smoke gases. In order to create a ventilation space (6) between the wall surround (5) and the casing (2) and to bring about an air flow through the ventilation space (6), the wall surround (5) surrounds the casing (2) at a distance. At the lower end of the wall surround (5), air inlet openings (8) are provided and, at the upper end of the wall surround (5), air outlet openings (16) are formed by the cover plate (10) being supported locally via plinths (15) on the wall surround (5). <IMAGE>
