EXPERIMENTAL DETERMINATION OF EXPLOSION CHARACTERISTICS FOR WOOD POWDER DERIVATED FROM TECHNOLOGICAL PROCESSES
Abstract
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 behavior which is represented by a mixture of air and flammable substance is 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, are intervening additional factors related to the physico-chemical properties of combustible solids, the shape and size of dust particles, as well as the environmental conditions under which dust exist in suspension. Industrial accidents involving flammable substances pose a significant threat both for people and the environment, causing economic losses and disrupting sustainable growth. To minimize the associated risks, measures are necessary to prevent fires and explosions, based on the knowledge of flammability parameters and to ensure appropriate preparedness and response should such accidents nevertheless happen. For this work have been performed flammability tests for wood powder derivated from technological processes, respectively minimum ignition temperature, lower explosion limit, the minimum ignition energy, maximum explosion pressure, the rate of pressure rise, ignition temperature in the layer and cloud ignition temperature.
