WHY BOILER EXPLOSION CAUSES SO MUCH DAMAGE?
A boiler explosion is a ruinous failure of a boiler. Any
Boiler explosion results in two major events:
·
The steam under pressure is
suddenly exposed to much lower pressure i.e. Atmospheric Pressure resulting it
to expand to almost 10-15 times expansion of its volume.
·
The tremendous amount of
energy stored in the pressurized boiler water is suddenly released prompting
sudden evaporation of 15 to 20% of the water to get converted into Flash steam.
This steam also expands to more than 1700 times its original volume causing
catastrophic damages
·
Aging containment that might have undergone a
degree of corrosion
·
Mismanagement such as unqualified boiler
staff
·
Water level that is much lower than the
designed level
·
Faulty gauges thereby allowing pressures
exceeding that designed for the drum
Impact of boiler explosion varies from
economic point of view due to time wastage during replacement and or repair, to
loss of life in cases of fatal explosions which in turn translates to loss of
manhours in the long run.It therefore goes without saying that awareness about
boiler explosion should be part of core values in running a boiler, this can be
achieved through:
·
Having a qualified personnel on site to
manage the boiler
·
Running scheduled preparedness drills
·
Regular boiler checks and services
