摘要

摘要本文论述了工业粉尘样品的燃烧特性的测定。根据en14034(爆炸下限LEL, Pmax, Kst)介绍了粒度、粒度测定和爆炸参数的测定。根据EN ISO / IEC 80079-20- 2:20 16的要求，测量了粉尘层和热表面分散粉尘的最低着火温度。LEL为60 g m−3,Pmax为8.61 bar, Kst为89 bar.s−1.1 m。粉尘层的最低着火温度为280℃，分散粉尘的最低着火温度为400℃。

Study of Fire Characteristics of Industrial Dust

Abstract The article deals with the determination of fire characteristics of industrial dust samples. Particle size granulometry and determination of explosion parameters according to EN 14034 (Lower Explosion Limit LEL, Pmax, Kst) are presented. The minimum ignition temperatures of the dust layer and dispersed dust from the hot surface according to EN ISO / IEC 80079-20-2: 2016 were measured. It was found that LEL is 60 g.m−3, Pmax is 8.61 bar, and Kst is 89 bar.s−1.m. The minimum ignition temperature (MIT) of dust layer is 280 ° C and the minimum ignition temperature of dispersed dust is 400 ° C.
