Expert view
“During the milling of grain and handling
of flour, friction/heat becomes a real
ignition risk. Advanced chemical
suppression systems are designed to
detect the start of an explosion (point of
ignition) and deliver dry, inert chemical
extinguishing agents into a developing
internal deflagration. These suppression
and isolation systems can be activated by
pressure, optical or vent sensors.”
advanced flameless vents intercept, quench and retain all burning materials, preventing them
from being expelled into the atmosphere. They are particularly
useful for dust collectors, bins and
bucket elevators.
ISOLATION
isolation systems can be activated by pressure, optical or vent
sensors. A possible deflagration travelling through
ducts, piping and connected
equipment is quickly and efficiently extinguished, thereby preventing the spreading of explosion damage.
Passive and active explosion isolation are designed to prevent any
type of deflagration or explosion
from spreading to other parts of
processing equipment via areas of
low pressure. This involves the installation of appropriate valves or
rotary screws on susceptible inlets
and outlets on the enclosure.
Where chemical suppression is
used to reduce the initial
increasing pressure in
an enclosure, hot
gasses will attempt to exit
such areas of
lower pressure.
PROTECTING YOUR BUSINESS
It is important to carry out appropriate risk assessments to
ensure the best protective solutions for use in a flour factory.
BS&B always offer a free factory
survey. This is essential for achieving optimal dust explosion
protection and is the first step in
ensuring that clients receive the
right explosion protection solutions for their business and their
staff, which are investments well
worth protecting. l
The IQR System is a solution for the
protection of process equipment
installed indoors.
FLAMELESS VENTING
If the worst happens and an explosion does occur inside a process or storage vessel containing
combustible materials, a rapid rise
in pressure can result, putting
both staff and equipment at risk.
Explosion vents are the preferred
passive method for relieving such
explosive pressure. The most
