STUDY OF THE INFLUENCE OF THE CONFIGURATION AND PARAMETERS OF FIRE FURNACES ON THE HEATING CONDITIONS OF BEARING WALLS UNDER THE STANDARD FIRE TEMPERATURE REGIME

Abstract

The purpose of this work is to determine the configuration of the furnace chamber and its parameters, which will ensure compliance with the fire temperature regime and the requirements in accordance with the conditions for carrying out fire tests of load-bearing walls.

In the FlowVision software complex, 3 computer configurations of fire furnaces were created to study the thermal effect on a vertical building structure, namely: a load-bearing wall, which differed in the geometric dimensions of the fire furnace chamber structure and the parameters of the holes for installing burners and the hole for the exit of combustion products. The research algorithm and determination of the model of the fire furnace chamber, which will ensure the adequacy and reproducibility of the results of the location of the installation of temperature control sensors, are specified. It is demonstrated how the design features of the furnace chamber affect the uniformity of temperature distribution on the heating surface of the load-bearing wall, the temperature of the installed temperature control sensors in the furnace chamber and on the heating surface of the load-bearing wall is calculated, and a graph of its change over time is plotted. It has been established which of the simulated configurations will provide the opportunity to conduct the most reliable studies of the thermal effect of fire on vertical building structures.
