摘要/Abstract

摘要： 为探究NH₄H₂PO₄粉末对蔗糖粉尘云着火燃烧的抑制作用,利用高德伯尔特-格润瓦尔德炉试验研究NH₄H₂PO₄-蔗糖混合粉尘云的最低着火温度(MIT)和燃烧过程。结果表明:质量浓度分别为1 363.6、1 818.2、2 272.7和 2 727.3 g/m³的蔗糖粉尘云中NH₄H₂PO₄的质量分数分别达到50%、55%、60%、40%时,其MIT分别为787、805、880、745 ℃;进一步增大NH₄H₂PO₄的质量分数,蔗糖粉尘云被完全惰化;NH₄H₂PO₄能有效抑制蔗糖粉尘云的着火燃烧,粒径越小,对蔗糖粉尘云燃烧火焰的抑制效果越明显。

Abstract: In order to explore the suppression effect of NH₄H₂PO₄ on the ignition and combustion of sucrose dust cloud, MIT and combustion process of NH₄H₂PO₄-sucrose mixed dust cloud were studied by Godbert-Greenwald furnace apparatus. The experimental results show that the MIT of sucrose dust cloud, which mass concentration of1 363.6, 1 818.2, 2 272.7 and 2 727.3 g/m³ respectively, is 787, 805, 880 and 745 ℃ when the mass fraction of NH₄H₂PO₄ reaches 50%, 55%, 60%, 40% respectively, that the sucrose dust cloud is completely inert with further increasing the mass fraction of NH₄H₂PO_4,that NH₄H₂PO₄ can effectively inhibit the ignition and combustion of sucrose dust cloud, and that the smaller the particle size of NH₄H₂PO₄ is, the more obvious the inhibition effect on the combustion flame of sucrose dust cloud will be.

Key words: sucrose dust cloud, minimum ignition temperature (MIT), NH₄H₂PO₄, suppression effect, inert dust
