Mobile Smoke Ventilation Equipments for Subway Fire Ground

摘要

Performances and characteristics of several mobile smoke ventilation equipments used in subway fire ground are discussed. Through a fire test carried out at the subway station of North Zhongshan road in Shanghai, the smoke movement status is investigated and the characteristics of smoke movement in subway fire ground are analyzed. Application tactics of mobile smoke ventilation equipments in subway fire ground are systematically elaborated. Such tactics i.e. positive pressure ventilation, negative pressure ventilation and hydraulic ventilation of firefighting nozzle are analyzed.
