Study of explosive characteristics of combustible powders.

Due to the continuous technical and economic development of the human society, a large number of chemical substances and compounds in the form of combustible dusts and powders are increasingly being used in the technological processes present in various industrial branches. These combustible powders, during their production, handling and storage operations, in combination with air, may lead to potentially explosive atmospheres. The presence of combustible powders and dusts, and possibly the appearance of potentially explosive atmospheres, has led to the need to adopt and enforce protective measures to ensure an acceptable level of protection in accordance with current rules, protective measures materialized mainly through use within locations endangered by the presence of potentially explosive atmospheres of properly protected technical equipment so as to reduce the possibility of ignition of the surrounding explosive atmosphere. Therefore, in order to be able to establish with certainty the requirements of the technical equipment that can be used in potentially explosive atmospheres generated by the fuel / air mixture, it is necessary to know the type of dust, as well as a series of parameters defining its sensitivity to ignition with different sources and the severity of the explosion it can generate, parameters known as explosive characteristics The paper highlights the explosive characteristics of combustible powders, the methods and equipment necessary to carry out experimental tests to determine these characteristics.
