Application
The M&C fluid particle filter CLF-5, CLF-5/W is suitable for filtration of fluid
particles of all types and is recommended for sample gases with an acid
dew point above 100°C. Examples are measurements in flue gas of heavy
oil and black coal combustions.
The filter separates the aerosols (very fine fluid particles) which still pass
the gas cooler. The most effective position of the CLF-.. filter is downstream
the sample conditioning close to the flow meter of the analyser. For
additional system protection we provide the version CLF-5/W with
integrated hydrophobic diaphragm, working as a liquid stop.
Description
The filter element of the M&C fluid particle filter is constructed in two
sections with a flow direction from the inside to the outside of the filter
element. The inner, very fine, fibre layer binds the fluid particles suspended
in the gas and leads them together with the gas flow to the outer, larger
layer. On their way through the filter element, the very fine fluid particles
accumulate with others and form droplets. The vertical flow direction and
the force of gravity cause the droplets to drip into the filter pot.
The filter element remains fully effective even when completely saturated
with fluid. If it is not effected by solid particles the lifetime is nearly
unlimited. The compressed Micro-Fibres are made with binding of PVDF in
order to prevent influence s on the sample gas.
The version CLF-5/W is equipped with an integrated liquid stop for water
and water identical liquids. The modified filter element clamp has a
protective hydrophobic diaphragm. In case the sample conditioning system
doesn’t work proper, the CLF-5/W will stop the liquid in front of the filter
outlet.
The condition of the filter is visible through the glass body without opening
the filter. The separated acid mist can continuously discharged with an
external mounted peristaltic pump SR25.1 (option) connected by a GL25
adapter. No tools are required to change the filter element. The optimised
position of the o-ring always guarantees a safe sealing of the filter body to
the filter head. The filter in- and outlet can be turned 180° on the mounting
bracket to achieve easy mounting and flexible adaptation to local
circumstances.
