| Abstract | Ovaj rad bavi se istraživanjem, analizom i primjenom sustava za gašenje požara vodenom maglom, koji predstavlja jedno od najučinkovitijih i ekološki prihvatljivih rješenja u modernoj zaštiti od požara. Sustav se temelji na korištenju finih kapljica vode pod visokim tlakom, koje omogućuju brzo hlađenje požara, smanjenje koncentracije kisika u zapaljivom području te sprječavanje širenja toplinskog zračenja. U usporedbi s konvencionalnim metodama gašenja, poput sprinkler sustava, vodena magla troši znatno manje vode, čime se minimizira sekundarna šteta uzrokovana gašenjem. Rad pruža detaljan pregled stabilnih sustava za gašenje požara te analizira prednosti i nedostatke različitih metoda gašenja, uključujući sustave bazirane na kemijskim sredstvima, plinovima i vodom. U radu su detaljno opisane ključne komponente sustava za gašenje požara vodenom maglom, poput mlaznica, visokotlačnih pumpi, cjevovoda, spremnika za vodu i kontrolnih jedinica. Objašnjen je princip rada sustava, uključujući mehanizme hlađenja, istiskivanja kisika i blokiranja prijenosa topline, koji zajedno osiguravaju učinkovito gašenje požara i smanjenje njegovog širenja.. Jedan od ključnih dijelova rada posvećen je prednostima i izazovima primjene ovog sustava u praksi. Pored tehničkih i ekonomskih aspekata, rad se bavi i regulatornim zahtjevima te standardima koji definiraju dizajn, testiranje i certificiranje sustava vodene magle. S obzirom na njegovu visoku učinkovitost i ekološku održivost, sustav za gašenje požara vodenom maglom sve se češće koristi u zaštiti kritične infrastrukture, industrijskih postrojenja, kulturnih i povijesnih objekata te modernih građevina. |
| Abstract (english) | This paper explores the research, analysis, and application of water mist fire suppression systems, which represent one of the most effective and environmentally friendly solutions in modern fire protection. The system is based on the use of fine water droplets under high pressure, enabling rapid fire cooling, reduction of oxygen concentration in the combustible area, and prevention of heat radiation spread. Compared to conventional fire suppression methods, such as sprinkler systems, water mist consumes significantly less water, minimizing secondary damage caused by extinguishing. The paper provides a detailed overview of fixed fire suppression systems and analyzes the advantages and disadvantages of different extinguishing methods, including systems based on chemical agents, gases, and water. It thoroughly describes the key components of water mist fire suppression systems, such as nozzles, high-pressure pumps, pipelines, water tanks, and control units. The working principle of the system is explained, including cooling mechanisms, oxygen displacement, and heat transfer blocking, which together ensure effective fire suppression and prevent its spread. One of the key sections of the paper focuses on the advantages and challenges of applying this system in practice. In addition to technical and economic aspects, the paper also addresses regulatory requirements and standards that define the design, testing, and certification of water mist systems. Due to its high efficiency and environmental sustainability, the water mist fire suppression system is increasingly used in the protection of critical infrastructure, industrial facilities, cultural and historical buildings, and modern structures. |
