Application

The M&C-prefilters are used together
with M&C gas sample probes series SP®
for continuous gas sampling in processes
with increased dust loading.

Description

The large active surface of the M&C prefilter
guaranties a long moulding time. Even in case
the flow rate of the sample gas is increased,
there is only a small difference pressure on the
filter matrix between clean gas and crude gas
side. Therefore, the solid particles do not get
into the filter’s pore structure. They are depos­ited as filter cake on the filter’s surface and
cause a prolonged moulding time in its prop­erty as prefilter. The M&C-prefilters SP2000 /
V20.. /V12.. /20SS are selected according to
the specific application. The basis for selec­tion are the process parameters, i.e. the gas
compounds, dust loading, grain sizes, water
vapure saturation, temperature, pressure and
gas velocity.

The M&C prefilters /V20.. are equipped
with a welded thread connector for
mountage into the mounting flange of
the M&C gas sample probe. For an opti­mal sampling position in the process, the
prefilters /V20.. can be mounted to the
sample probe via an extension tube /Vm...
In case of a high velocity of the process gas,
shape protection plates /AB.. are used in
order to protect the prefilters /V20.. against
abrasion.

The prefilters /V12-... have got a mount­ing flange adapter of stainless steel,
executed with 4 threaded bolts for
easy mounting. The prefilter versions
/V12-.. /SS, /V12-.. /IC are equipped with
a welded protection tube of stainless
steel or Incoloy on the mounting flange
adaptor. The feeding of process gas is made
via the three longitudinal slots distributed on
180° tube periphery. The special double-ply
construction of the prefilter /V12-1, /V12-3
is granting a particularly high back purging
efficiency.

Depending on fabrication, the prefilters /V20..,
/V12.. are partially made of different material
combinations. See table. For reduction of the
delay time in case of a small sample gas flow,
prefilters with volume displacer have to be
used.

The M&C tube prefilter /V20-T of PTFE cloth
with interweaved metal filaments for reduc­tion of the surface resistance (in order to
avoid frictional electricity) disposes over an
excellent back purging quality. It is used for
example in case of gas sampling out of coal
bunkers with a high content of superfine
dust.

The prefilter /20SS 150 is used for direct
mounting on the M&C sample tubes SP2000/
SS. It is supplied with a shape protection plate
and a tube fitting with double cutting ring.

If there are problems eg. in case the depth
for assembling is too small or the flow veloc­ity is too high, or the dust content or the
temperature are too high, then the electrical
heated adapter tube /AR should be used. It is
equipped with a flange connection at both
sides and is to be mounted on the plant’s
connection flange.
