Spark Arresters
Western Tydens Spark Arresters are
designed specifically for preventing the risk of fire
due to the ignition of flammable materials, caused by
spark emissions from the exhausts of internal combustion
engines. The risk of fire caused by exhaust sparks is
so high that access to many sites is barred unless engines
are fitted with spark arresters, and many countries have
legislation to this effect. The risk is greatest with
diesel engines, where carbon deposits can build up and
be ignited. The high ratio of oxygen which is present
in the exhaust pipe (when the engine goes off load) maintains
the ignition of partially burnt carbon particles which
are then discharged as highly dangerous sparks.
Western Tydens Spark Arresters are ATEX
approved and are designed on the centrifugal principle,
which has the effect of spinning the live carbon particles
in the exhaust gas at high velocity against the outer
casing, where they are retained until burnt, rendering
them inert before discharge. This advanced unit design
in all of our ranges is robust and maintenance free
and avoids the problems of blocking and burning out
associated with mesh and gauze type designs.
The primary range of spark arresters can be used
to replace the existing silencer, they will maintain
sufficient noise attenuation for normal industrial use,
with no significant increase in back pressure. Where
further noise attenuation is required, the units can
be fitted in series with a normal silencer. Alternatively,
the secondary range of simple add-on units are
available for temporary installation, in conjunction
with a standard exhaust system.
