N2  - To find the thermal hazard of new activated-carbon and used activated-carbon dusts, we investigated first the weight loss by one temperature increase using thermogravimetric analysis (TGA) and the properties of dust explosions with varying specific surface area of the dust with the same particle size. The Hartman apparatus is used to measure dust explosion by electric ignition after dispersing the dust by compressed air and then conducting experiments using varying concentrations and sizes of activated carbon dust. The results show that the explosion pressure of both forms of activated carbon are increased as specific surface areas are increased. If they are of the same particle size, new activated-carbon with specific surface area more than three to four times than that of used activated-carbon had a much greater propensity for dust explosion.     <p>Language: en</p>
