Požárně-technické charakteristiky brusného prachu

Abstract

The main objective of my thesis is a self-ignition of dust after mechanical processing of products. Thesis is divided into three main sections. First section describes dust, used fire technical characteristics of dust and theoretical introduction into spontaneous combustion. Second section gives a description of production facilities and technologies from where the examined dust comes from, including risk assesments for particular production environments. Finaly the third section contains results of ignition temperature tests of dust clouds and dust layers to ČSN EN 50281-2-1, setting self-ignition temperature according to ČSN EN 15188 and determination of flammability according to ČSN EN 64 0149.
