Experimental Study on Evaluating Smoke Control System Performance in a Transfer Station

Abstract

Full-scale experiment is an important method for fire safety in subway system. This paper presents an experimental investigation with a full-scale hot smoke test to evaluate the performance smoke control system including mobile ventilation and smoke discharge equipment in a curtain huge metro transfer station. Results showed that when the smoke control fans were activated, the smoke raised up rapidly and formed an accumulated smoke layer above the net-type ceiling and the velocity on the stairs was not conformed to the Code for Metro Design. Moreover, it is also found the mobile ventilation and smoke discharge equipment would disturb the smoke flow stability. Therefore, the mobile system should be selected as assistant equipment for the fixed smoke control system in the metro station.
