Abstract

In this paper, the PyroSim software is used to simulate the fire in an elderly apartment and analyze the vertical and horizontal variation characteristics of temperature, visibility, CO volume fraction, O2 concentration and flue gas layer height caused by fire combustion. The results show that the first floor is the fire floor, which is the most seriously affected by the fire. The temperature quickly reaches 70℃ at about 91-280s. To 54~265s, visibility rapidly decreased to less than 10m. The 1st to 6th floor of stairwell No.3 cannot be evacuated because the temperature reaches the value. Finally, the available time for the elderly evacuation is obtained, in order to provide a basis for the fire evacuation design and safety management of the elderly apartment.
