abstract="In order to identify effects of APP on flame combustion characteristics of sugar dust, vertical open square experimental platform of pipe burning was used to study influence of APP with different mass fractions on characteristics, velocity and temperature of flame. Then analysis was made on pyrolysis of sugar dust and its mixture with APP by using thermal analyzer. The results show that flame brightness of sugar dust will gradually decrease as APP mass fraction increases. With an addition of APP of 6% mass fractions, the maximum propagation velocity of flame in pipelines will decrease from 17. 3 m / s to 2. 8 m / s, its maximum temperature decreases by 46. 46% and residual amount of pyrolysis products increases from 0. 71% to 16. 06%. Flame inhibition effects of APP on powdered sugar include physical inhibition and chemical inhibition with its decomposition reaction absorbing heat from combustion reaction while decomposed products capturing free radicals from it, thus achieving the purpose of inhibiting flame propagation of powdered sugar. © 2019 China Safety Science Journal.
