4. DEVICE AND ACTION PRINCIPLE
4.1. The powder fire extinguishing installation “Buran-100ST-ESG” (see Fig. 1) consists of
two powder fire extinguishing modules “Buran-50ST” (U1) - 1, a holder for modules 2, fixing
clamps for modules 3, fasteners -4. Installation and movement of the kit is carried out with the
help of a rack with an eye- 5.
The “Buran-50ST” module (U1) (see Figure 1) consists of a hermetic steel case filled with fire
extinguishing powder, a gas generator (located inside the steel case) - 6, an ESG-0.5 electric
igniter, 7, an extinguishing powder neck. 8, the guide neck - 9 with a membrane assembly - 10.
At the outlet of the membrane assembly there is a G 1 thread for connecting the guide pipe (in
the transport position, the membrane assembly is closed with a plastic plug).
Installation in the fire extinguishing system up to the moment of launch does not have excessive
pressure inside the case.
4.2. The operation of the installation is as follows.
When a current pulse is applied, the gas generators of the modules are started, an intensive
gassing occurs, which leads to an increase in pressure in the modules' case and aeration of the
extinguishing powder in them. When the working pressure in the module housings of the
membrane module is destroyed by notches (bent in the form of petals) and the fire extinguishing
powder through the guide pipes and sprayers is fed into the protected space.
