Study on the influence of smoke spreading on fire detection in atrium space

Abstract

Abstract:

Mathematical simulation is carried out to study the fire smoke spreading and detection process of atrium with different ceiling heights. The temperature near the ceiling and visibility cloud chart are studied. The parameters curve features of linear beam smoke detection, extinction coefficient, and temperature with different ceiling height are analyzed.Results showed that, when the time of extinction rate near the ceiling reaching 50%/m and the ceiling height have good functional relation of y=26.58 × 1.06x, R=0.996; when the ceiling height is not less than 30 m, arrange the linear beam fire detector vertically is a good choice. The study can provide technical reference for the fire design of atrium and the arrangement of fire alarm system, and improve the building fire safety level.
