- Abstract
- ONLY ABSTRACT IN ENGLISH The objective of the project was to investigate the performance of flexible sectioning with a water sprinkling system. Different types of flexible sectioning such as fire curtains and jalousies were experimentally studied. The experiments carried out was focused on finding the minimum amount of water needed in order to keep the radiation level obtained at the unexposed face of the section on an acceptable level. Two different experimental set-ups were used. In the first set-up a container with the dimensions (width x height) 2,2 m x 5,2 m was used as a furnace. The advantage with the container was the height that could be obtained. The other set-up was a conventional fire test furnace with the dimensions (width x height) 3,O m x 3,O m. In both test set-ups the temperature was kept constant at different levels, and the amount of water applied to the sectioning was varied. The experimental results showed that a relatively small amount of water gave a significantly better performance of the flexible sectioning when considering the radiation levels. A mathematical model has been developed with which the needed amount of water can be calculated. The model was calibrated to experiments made with steel plates and curtains mounted on a provisional container furnace, and later verified on the tests made with a conventional fire test furnace.
