Accidental explosions and fires caused by combustible dust are some of the most significant threats in many industries where layers of combustible dust and clouds are formed as a result of technological processes. Combustible powders react with air oxygen in a process known as oxidation, which produces carbon dioxide, carbon oxide, water, and other gases whose contents depend on the temperature at which the oxidation occurs. The dust cloud is the main form of existence of combustible dust in the production area and together with the existence of effective ignition sources are the main causes of dust explosions in production processes. Dust explosions are mainly characterized by the minimum ignition temperature, explosion limits, the minimum ignition energy, maximum explosion pressure and the rate of pressure rise. The explosive behaviors which is represented by a mixture of air and flammable substances are influenced by many factors of which the most important parameters are the chemical composition and concentration of flammable and explosive mixture with air. In particular, for the combustible powders intervening additional factors related to the physic-chemical properties of combustible solids, the shape and size of dust particles, as well as the environmental conditions under which dust exist in suspension.
For this work flammability tests have been performed for powder mixture of starch and magnesium respectively minimum ignition temperature, lower explosion limit, explosion pressure, the maximum rate of pressure rise, minimum ignition temperature in the layer of the dust cloud.
