摘　　要：建立舰船火灾烟气控制模型舱,针对移动式风机在正压送风时距离火源不同位置、风机仰角不同工况下,试验分析火灾烟气温度、能见度及CO浓度在空间和时间上的变化规律,结果表明,正压送风在防止烟气溢流的同时,可有效排出舱室内烟气,降低舱内温度,提高火场能见度。移动式风机在距离着火舱室门口1.5 m处,且风机仰角为20°时,能最大限度地封堵烟气的溢流。Experiments were carried out in the fire smoke controlled cabin model. The temperature of fire smoke, visibility and C0 concentration varied with time and space in different distances from the fire room and the angles of the portable smoke Ventilator was studied under pressure ventilation. It was concluded that the pressure ventilation can prevent the smoke overflow, exhaust the smoke, reduce the temperature and improve the visibility. The best position is 1.5m from the door of the smoke cab- in, and the best pitch attitude is 200, which can get the better effect of the smoke exhaust.
