Vliv vybraných iniciačních zdrojů na výbušnost prachovzduchových směsí.

Abstract

The autor in his work tempts to judge the influenceson explosion parametres. Mixture of dust had been initiatied by different sources in the vessel of 20 l volume. The trial samples were the mixture of flour dust-air and the mixture of coal dust-air. The inflammable sources had the same energy (10kJ). During the attempt initiatory sources of Polish and German (Sobbe) production were used. Maximum explosive pressure Pmax and maximum pressure growth speed (dp/dt)max were monitored during the explosion. These parametres were subsequently compared and the results were evaluated. These evaluations had become the basis of the work’s aim‘s conclusions.
