THE CALCULATING PROGRAMME FOR THE SCALING
OF A SYSTEM VENTILATION AND SMOKE AND
HOT GASES EXHAUST FROM AN ARSONED BUILDING
The personal programmed SVEFGF, conceived on the base of the
standardized calculating procedures (CEN/TR 12101-5:2007), allows the
minimizing the calculus methods, with the purpose to follow, to compare, and
to evaluate the obtained results, regarding to chose the best solutions for
scaling of system ventilation and smoke and hot gases exhaust from an arson
building. The utility of this program is represented through the application
proposed in the paper for the depressurization of an atrium with opened floors
towards this.

THE EXPERIMENTAL INSTALLATION FOR THE STUDY ON
THE FORMATION OF HOT SMOKE AND GASES IN A
BURNING ENCLOSURE AND ON THEIR FLOW THROUGH
THE VENTILATION OPENINGS
This paper is an experimental proposal to view and analyze the movement
of smoke and hot gases and the formation of the smoke layer in a burning
enclosure, the latter depending on the degree of ventilation of the room,
thermal loading of the furnace and the thermal inertia of the enclosure. Inside a
sufficiently ventilated burning enclosure, two areas develop: the upper –
containing smoke and hot gases – and the lower one, containing relatively fresh
air. Experiments conducted in this research were primarily aimed at
demonstrating the basic theory that the thickness of the above layers depends
on the ventilation holes and the size of the firebox.
