Pyrosim burner
« on: May 16, 2019, 07:39:42 am »


I'm modelling a building with an atrium. The atrium is 12m in length, 15m in width, and 9m in height. Height of each floor is 3m. There are 1.6 m wide walkways around the atrium at 3m and 6m high levels.

The fire needs to be medium-type of 2.5Mw (2500Kw), how would you calculate the HRRPUA ,please?

How big is your burner going to be?

HRRPUA = HRR per unit area

HRRPUA = 2500 kW / area of the burner
