PyroSim / Increasing temperature reached by the burner
« on: July 21, 2022, 08:22:56 am »
hi everyone,
I hope someone will come to my aid. I'm studyind the evolution of a fire on the facades of building of great heigh.
The fire starts inside a room and it should expand to the facade throgh an oper window. The facade, from the inside to the outside, has a layer of concrete, one middle layer of PIR and a thin layer of aluminium. What I'm trying to do is to reach the ignition temperature for PIR wich should be around 400°C.
Speaking about the HRR curve used for the burner I tryed two ways:
- HRR of a office workstation took from Handbook SFPE
- defaulf HRR curve gived by italian standards for civil activities
(attached on the bottom)
In both cases the maxim temperature reached is only around 250°C which is not enough.
Can anyone give me any suggestion on what to change? Thank you
