Aerosolové hasící systémy

Abstract

The knowledge of burning substances processes is a basic prerequisite for their extinguishing and simultaneous use and the most suitable extinguishing technology. Fire extinguishing media with the growing knowledge of chemicals and their effectiveness is constantly evolving and in the final stage have the potential to eliminate the secondary damage arising in the case of fire interventions as much as possible. Aerosol extinguishers are one of these new progressive substances. This PhD thesis is focused on a new scientific investigation of their effectiveness in various operational and technical environment, the title „Aerosol fire extinguishing systems“ implies its importance and urgency of detailed scientific research. The effects will be analyzed in the experiments, temperature curves of fire extinguisher generation, determined particle sizes and investigated effects of aerosol sediment on various substances, especially metal components of technological units technical infrastructure. In the individual chapters of this thesis he analyzes the ways of aerosol fire extinguishing reactions in various hypothetical environments and subsequently presents graphs and tables analysis of measured values in different situations which may occure in fire events. Very important part of the thesis is also a chapter on the suitability or unsuitability of aerosol extinguishing agent use, depending on the environment type and alternative negative outcome of its usage that may occur underestimating knowledge of its chemical composition. The experiment outputs will have a potential to expand knowledge about effects extinguishing agents when used in practice. It will also enable their potential users in particular make a balance on its wider expansion in order to eliminate primary and secondary damage caused by fires.
