Abstract / Description of output

This paper focuses on a new generation of hot smoke tests, using premixed propane flames as a fire source. Premixed flames burn in a highly efficient manner. Thanks to this high combustion efficiency, the flame length is reduced and, consequently, the local temperatures at the ceiling directly above the burner are lower. In fire tests, this allows the level of structural protection above the burner to be reduced. Also, the radiation from the flames is dramatically reduced and heat is almost totally released as convective heat.

The equipment design allows the user to control the heat release rate of the apparatus in real time. Pre-defined ‘fire’ curves can be reproduced to study the reaction of the detection systems or to evaluate smoke filling times.

Real tests and computer simulations using FDS were used to study and describe the system. Due to the lack of literature regarding the plumes created by premixed flames, it was necessary to run real tests, take measurements and create a computer model in order to collect information and assess the burner performance.

The comparison between the real tests and the computer model allowed the validation of the simulations. The test results showed that the developed testing methodology is suitable to replicate realistic smoke conditions.
