In Finland, there have been numerous recent building fires where the fire has started from structures locating near the chimney roof penetrations. One possible reason for these fires is that the actual flue gas temperatures in the real use of fireplaces are higher than assumed in the standard fire testing. High gas temperatures may cause overheating and ignition of combustible materials adjacent to chimneys. An experimental study has been carried out by Tampere University of Technology to determine the flue gas temperatures of fireplaces and chimneys in real use in residential buildings. The tested fireplaces included sauna stoves, room heaters and slow heat release appliances. Field measurements demonstrated much higher flue gas temperatures and flue draughts than are applied in the EN standard tests and indicated in the CE marking. The main results of these field tests are introduced in this presentation.
