  • 摘要
    为了研究阻化剂对煤燃烧特性的影响,选取柠檬酸钠和聚磷酸铵进行复配,开展复合阻化剂优选的实验研究。采用锥形量热仪在45kW/m2的热辐射强度下,分析阻化煤样的燃烧行为和阻化效果。结果表明,在选取的实验比例中,当柠檬酸钠与聚磷酸铵的质量比为3∶1时,煤燃烧的热释放速率和总热释放量明显降低,烟气持续生成时间有效缩短,抑制了烟气的产生,体现出优良的阻燃抑烟效果;在煤炭的燃烧效率方面,提高了体系的火灾性能指数,降低了火灾增长指数,有效抑制了煤炭的燃烧,表现出复合阻化剂良好的协效作用。
  • Abstract
    In order to study the effect of the inhibitor on the combustion characteristics of coal, sodium citrate and ammonium polyphosphate were mixed to carry out the experimental study on the optimization of the compound inhibitor. The combustion behavior and blocking effect of the retarded coal sample were analyzed with a cone calorimeter at the thermal radiation intensity of 45 kW/ m2. The results show that among the selected experimental ratios, when the mass ratio of sodium citrate to ammonium polyphosphate is 3 ∶ 1, the heat release rate and total heat release of coal combustion are significantly reduced, the smoke generation duration is effectively shortened, and the smoke generation is inhibited, reflecting excellent flame retardant and smoke suppression effects. In the combustion efficiency of coal, the fire performance index of the system is improved, and the fire growth index is reduced. The combustion of coal is effectively inhibited, showing a good synergistic effect of the compound inhibitor.
