火灾问题一直是船舶安全的重大威胁,控制船舶火灾烟气是降低船舶火灾危害的重要手段。火灾过程中产生的烟气以及悬浮颗粒统称为火灾中的烟气,烟气具有非常严重的危害性,主要是对人体身体和心理造成严重的伤害。但是,目前对于船舶通风条件下的火灾烟气特点研究不够深入,对其了解不清晰,因此给船舶火灾灭火救援问题造成严重的影响。通过论证船舶火灾烟气流动特性,为促进船舶火灾烟气的控制和事故应急处理救援决策提供科学的依据。本文以嘉年华号游轮作为研究对象,分析了该船舶的火灾特性和烟气运动特点,深入研究了船舶火灾危险性及消防现状,为船舶火灾烟气控制技术提供指导和建议。 Fire has always been a major threat to the safety of ships. Controlling smoke from ships’ fires is an important means to reduce the fire hazard of ships. The flue gas and suspended particles generated during the fire are collectively referred to as the flue gas in the fire. The flue gas is very harmful and mainly causes serious physical and psychological harm to the human body. However, at present, the research on the characteristics of fire smoke under the condition of ship ventilation is not deep enough and its understanding is not clear enough, so it has a serious impact on the fire fighting and rescue of ships. By demonstrating the fire smoke gas flow characteristics of ships, it can provide a scientific basis for promoting fire smoke control and accident emergency rescue decision-making of ships. In this paper, the Fiesta cruise ship is taken as the research object. The characteristics of the fire and the characteristics of the flue gas movement are analyzed. The fire risks and fire fighting status of the ship are also studied in depth. The paper provides guidance and suggestions for the ship fire flue gas control technology.
