With the growing evolution of the chemicals and materials, the steps of chemical process have become increasinglycomplicated and sophisticated. There is a concern that treated dust of sugar, when produced on an industrial scale, will result inserious explosion accidents. There include test of explosion sensitivity and data processing by minimum ignition energy tester(MIET) and rough set, respectively. Five important factors of explosion discussed in dust of sugar are particle size, particlecomposition, temperature, as well as the relative humidity of environment. The orders of significance are particle concentration >temperature > particle size > humidity. The temperature explosive range of powdered sugar is about 19°C, and it will explodewhen the humidity is between 55% and 75%. When the particles of dust trend to minimum, the more amount of dust is required. |
