<p>Stationary chimney cowl has a stub pipe to be connected to the chimney and further pipe piece(s) connected at 90 deg. and in a T-shape with the stub pipe, and which has exhaust gas openings, these at the ends having each a screen element. The further pipe piece has an outer end middle upper exhaust gas opening protected by a part-cylindrical bent screen element. At least the screen elements on the exhaust gas openings of the free ends each have a conventional diffusion cone at the inner side. The design is simple and effectively discharges gases with any wind direction, and prevents outer air passing into the chimney.</p> |
