Influence of the installation depth of the easily dumped structure on pressure in the room during a gas explosion

The paper investigates the possibility of regulating the efficiency of structures (EDS) to reduce the pressure inside the room during an internal explosion in it. It easily dumped is noted that at the explosion stage preceding the beginning of the gas flow through the opening, the pressure increase can be minimized by reducing the installation depth of the EDS in the opening, reducing the mass of the EDS unit area and weakening the EDS attachment points to the building frame, that is, approaching the beginning of the opening process. After the beginning of the gas flow, the effectiveness of the EDS can be increased by increasing the perimeter of the opening, which is covered by an easily dumped structure. If the rate of explosive combustion is so high that the explosion develops faster than the release of gases is accelerated, it is necessary to increase the area of openings, preferably with an increase in their perimeter, both by changing the shape and by increasing their number.
