The invention relates to a device for evacuating combustion gases from a building having one or more openings 2 made in the roof 1 of the building which are possibly connected to fire shafts 10. According to the invention, jet nozzles 7 are arranged in an opening 2 and/or a fire shaft 10, which jet nozzles are fed with outside air from a fan 5 mounted beside the opening 2. The jet nozzles 7 are directed such that, in a fire, they produce an air current out through the opening 2 and hence increase the flow of the combustion gas out through the opening 2. <IMAGE> |
