Effects of the Coupling of Insulating and Conductive Materials to Limit the Temperature at Chimney-Roof Penetration

Autor: Davide Luscietti, Perttu Leppänen, Sandro Bani, Mariagrazia Pilotelli, M. Alanen, Manuela Neri

Recently, many roof fires have occured in Europe due to the presence of a chimney. Since also certified chimneys were involved in the fires, chimneys producers have attempted to propose some solutions. However, these latter may sometimes not be effec

Experimental study on fire safety of chimneys in real use and actual site conditions

Autor: Timo Inha, Mikko Malaska, Matti Pentti, Perttu Leppänen

Publikováno v: Journal of Building Engineering. 14:41-54

In recent years, numerous building fires have occurred in Finland where the fire has started due to the ignition of flammable materials in the vicinity of metal chimney penetrations through floors, roofs and walls. Based on onsite observations and ex

Experimental Study on the Smouldering Combustion of Mineral Wool Insulation in Chimney Penetrations

Autor: Mikko Malaska, Perttu Leppänen

A large number of fires have been caused by metal chimney penetrations in recent years. One factor that has contributed to these occurrences is smouldering combustion within mineral wool, which is often used as insulation in metal chimneys and their

Experimental and Computational Study of the Temperatures Field Around a Chimney Roof Penetration

Autor: Mariagrazia Pilotelli, Sandro Bani, Matti Pentti, Perttu Leppänen, Manuela Neri

Publikováno v: Fire Technology. 52:1799-1823

The number of roof fires due to the passage of chimneys is high. Since the experimental procedure necessary to identify all the variables affecting the temperature reached by roof in the vicinity of a chimney would be expensive, a 2D numerical model

Comparison between European chimney test results and actual installations

Autor: Mariagrazia Pilotelli, Manuela Neri, Sandro Bani, Perttu Leppänen, Davide Luscietti, Matti Pentti

European standards regulate the certification procedure for determining chimney class temperature and the distance at which to install chimneys from combustible materials. These standards prescribe the heat stress test and the thermal shock test. The

An Experimental Study on the Effect of Design Flue Gas Temperature on the Fire Safety of Chimneys

Autor: Matti Pentti, Timo Inha, Perttu Leppänen

Publikováno v: Fire Technology. 51:847-866

Recently, numerous fires have started in Finland around roof penetrations of metal chimneys. One reason for the fires is the high flue gas temperatures of fireplaces. EN standards do not determine the flue gas temperatures of fireplaces meant for the
