diplomska naloga
Abstract
Na področju industrije se je povečala uporaba materialov in snovi, ki ogrožajo človekovo zdravje in življenje, še posebej v primeru požara. Zaradi tega je postalo vse bolj pomembno, da so industrijski objekti pravilno projektirani in da v primeru požara ne ogrožajo človekovega zdravja in življenja ter okolja. Za ocenjevanje požarne varnosti se izvajajo tudi požarne simulacije z računalniškimi programi. V prvem delu diplomske naloge sem povzela osnove gorenja, produkte gorenja in značilnosti požarov v objektih. Analizirala sem statistične podatke s področja požarov v Sloveniji. Nato sem proučila obstoječe zakonske zahteve na področju požarne varnosti in požarne gradnje. V drugem delu diplomske naloge sem izvedla simulacijo požara v objektu lesnopredelovalne industrije, v katerem uporabljajo različne lake. Objekt me je zanimal predvsem zaradi svoje velike požarne obremenjenosti. Simulacijo sem izvedla s programskim paketom Fire Dynamics Simulator (FDS) in Smokeview (SMW. Izvedla sem 8 različnih variant, s katerimi sem poskušala določiti vpliv prisotnosti laka, posameznih konstrukcijskih elementov, vetra in gašenja s CO2 na dinamiko širjenja in koncentracije produktov gorenja. Na osnovi rezultatov simulacije sem za posamezne dele objekta naredila primerjavo med variantami. Analizirala sem dobljene koncentracije CO in CO2 ter ugotovila ali potencialno ogrožajo človekovo zdravje in življenje. S pomočjo dobljenih rezultatov za CO in CO2 sem predpostavila dinamiko gibanja morebitnih strupenih produktov gorenja, ki lahko nastanejo pri gorenju poliuretanskega laka. Na podlagi ugotovitev sem predlagala izboljšave za boljšo požarno varnost.

Secondary title: |
Fire analysis and combustion products in a wood processing industry facility |
Secondary abstract: |
In industry the use of materials and substances that pose a threat to human health and life, especially in case of fire, has increased. Therefore it has become more and more important that industrial facilities be designed properly and that, in case of fire, they not pose a danger to human life and health and the environment. For the assessment of fire safety, fire simulations with computer software are made. In the first part of the thesis, I summarized the basics of combustion, combustion products and the characteristics of fires in buildings. I analyzed the fire statistics in Slovenia. I then examined the existing legal requirements for fire and building safety. In the second part of the thesis, I conducted a fire simulation in a wood processing industry facility where different wood coatings are used. I was particularly interested in the facility because of its large fire load. I conducted the fire simulation with Fire Dynamics Simulator (FDS) software package and Smokeview (SMW). I did 8 different fire simulation variants in which I have tried to determine the influence of the wood coating presence, individual design elements, wind and fire extinguishing with CO2 on the Dynamics and concentrations of combustion products. Based on the simulation results I made a comparison between the variants for the individual parts of the facility. I analyzed CO and CO2 concentrations and determined whether they are a potential threat to human health and life. Based on the CO and CO2 results, I estimated the dynamics of toxic combustion products, which can be generated by burning of the polyurethane wood coating. Finally, I suggested improvements for better fire safety. |
