ASSESSMENT OF FIRE DISTANCES BETWEEN OBJECTS OF DIFFERENT PURPOSES. FIRE IN PREMISES OF RESIDENTIAL AND PUBLIC BUILDINGS. CALCULATION EXAMPLE

The work continues to consider approaches to the justification of fire gap reducing between objects of different functional purposes and is a continuation of publications [1–4]. There is carried out the evaluation of the temperature in a room (fire compartment) at fire at the mode controlled by ventilation, as the maximum temperature value is reached. Fire in a room on the first floor of a three-storey kindergarten building is analized. There are considered two limiting cases of heat exchange with room walls: isothermal and adiabatic. The calculation is carried out for the characteristic parameters of residential and administrative buildings (where fire occurs). The solution of the system of 7 transcendental equations was carried out by Seidel method for two limiting cases: adiabatic and isothermal. The temperature values were close (the difference was ≈ 0.5 %).
