METHOD TO PREVENT THE FIRE SPREAD OF HAZARDOUS GASES AND RADIONUCLIDES

The purpose of this experimental and theoretical study is to prevent fire spread in all type of fires and improve the fire and explosion safety for LNG storage as well as nuclear power plants to prevent hazardous gases and hot combustion products containing radionuclides. Thus implemented by accomplishing the application of innovative technology “Sogda” into practice. The design of a screen “Sogda” consists of two parallel metallic grids stretched over metallic frames. Active special water spray nozzles located between two parallel fixed grids creates water film on the surface of grid and water vapour droplet-air medium in the space between two parallel grids. This complex process partially attenuates the radiant heat flow from 45 to 100 or more times, representing mainly in electromagnetic waves in an IR diapason, as a result of thermo-physical effects and it is optical phenomena that prevents the passage of explosive toxic gases. The latest experimental data is given (from 2010–2012 Orenburg, Russia).
