Explosive moments: the spark often occurs at unexpected locations

Typical applications where explosionrisks exist:

• Mills

• Mixers

• Conveyors

• Elevators

• Pneumatic conveyors

• Silos, bunkers

• Sieves

• Spray dryers

• Fluid bed dryers

• Filters, cyclones

• Shredders

• Reactors

• FIBCs (Big Bags)

• Aerosol Fill Rooms

• And many more!

How can an explosion be initiated from a dustor gas air mixture?

When a flammable mixture occurs simultaneously with sufficient

oxygen and an ignition source. This is the classic fire triangle.

Eliminate any one of these and an explosion will not occur.

Typical ignition sources include:

• Hot surfaces occurring in mills, mixers, fans, etc.

• Mechanical sparks (friction, grinding, impact)

• Electric equipment

• Smouldering combustion

• Electrostatic discharges (cone discharges, brush discharges,

propagating brush discharges and sparks)

Reducing the consequences of explosions

Explosion suppression installations are designed to prevent the generation of high

pressures by fuel-air explosions in vessels. Explosion suppression installations do

not prevent an explosion from occurring but mitigate its effects on the protected

equipment and personnel. The flames are quenched in the early stages of explosion

development. In this way personnel in the vicinity of the installation are protected

from being hurt, and destruction of the installation is prevented.

Extinguishing post-explosionfires

After an explosion a fire in vented

installations is not uncommon. This is

particularly common if explosion doors

do not close after operation.

To avoid further damage by a post-explosion

fire, fire protection systems are installed

(Aquasafe®, powder, CO2, Argonite®,

FM200®, etc.). The choice of the fire sup-

pressant is based on the product

properties. The fire is detected early

during its development using temperature

sensors which are unaffected by pollu-

tants and will automatically extinguish

the fire.

Avoiding explosion transmission

To prevent pressure waves and/or flames being mitigated to other plant areas,

isolation devices must be fitted such as:

• Extinguishing barriers (chemical)

• Fast acting slam shut slide valves

• Ventex-valve

• Diverter with extinguishing barrier

Explosion isolation of a filter designed to withstand 10 bar over pressure

The dust control devices of Dustalert allow for continuous monitoring and indication of dust emissions in dust collectors as well as the early detection offilter damage

Installed in conjunction with explosion protection systems, dust control devices are mounted on the clean airside

of the filter. The potential presence of an explosive dust-air mixture on the clean airside is extremely alarming as

normally no constructive protection measures are applied on this side. An explosion caused by the fan as potential

ignition source could therefore destroy the equipment. Effective monitoring and early detection of hazardous

dust concentrations offer excellent protection against explosions.

The additional control of the filter bags provides extra protection for the environment.

• No optics

• Practically maintenance free

• Simple mounting

• Dust emission trend analysis and monitoring of filter damage

• Innovative microprocessor controlled sensor (patented TriboACE®-method)

• Applicable for several types of filters and ducts

Dust control device DS-10, digital output

Dust control device DS-30, 4-20 mA output

Dust control device DA-50 for moist products and high temperatures

Kidde Explosion Protection sensor technology

Such a control can be achieved by:

• Rate of pressure rise or static pressure

• Temperature

• Flames

In production facilities the protection devices must be installed with process

independent sensors. The explosion multi-sensor MEX-3 can detect potential

hazards at a very early stage in the explosion process.

Thermal explosion

This process is referred to as

runaway reaction or thermal

explosion. This possibility can

arise when:

• materials become thermally

unstable

• strong exothermal reactions

are maintained

• there is an unacceptable

increase in heat production

• there is an unacceptable

accumulation of the reaction

potential

• insufficient heat of reaction

is removed

Controlling spurious events

Several measures can be used

to prevent unwanted events,

such as the concepts of mea-

suring, control and regulating

technology, shutdown systems,

emergency cooling or organi-

sational measures aimed at

eliminating potential hazards.
