Application
M&C has developed a special sampling tech-
nique for continuous gas sampling of waste
gas in DENOX plants (SCR) where NH
3
is
added to the flue gas in order to reduce the
NOx content. This new sampling technique
has also proved to be suitable for processes
with very high pollutant concentrations.
In these applications, a big problem
is the measurement of NOx, SO
2
and
O
2
-concentrations. With temperatures of <
300 °C, ammonium salts are produced due to
the chemical reaction of NH
3
and SO
2
/SO
3
in
the flue gas.
This salification blocks up filters and sample
lines in a short time.
The special M&C gas sample probe SP2000-
H320/S represents a good solution for these
problems. In order to prevent a blocking
due to salification, the probe temperature is
adjusted above 300 °C.
Description
The M&C gas sample probe SP2000-H320/S is
based on the standard sample probe.
The gas sample probe SP2000-H320/S is tem-
perature controlled via an integrated capillary
sensor thermostat adjustable from 50 to 320
°C and including over temperature limiter and
low temperature alarm.
As an option, the gas sample probe is availa-
ble with a FeCu-Ni thermoelement instead of
the thermostat controller. For this version, an
external temperature controller is necessary.
Due to the modular design the M&C gas sam-
ple probe SP2000-H320/S can be equipped
with the wide range of different sample tubes
and pre-filters respectively options.
At the sample gas outlet of the probe, the
gas passes a heated adapter to a non-heat-
ed condensate vessel of glass. It is filled
with glass balls to extend the surface for
the salification. The salt deposits and can
be washed out with the condensate.
A peristaltic pump SR25.1G removes the con-
densate with the solved ammonium salts.
The temperature of the vessel is higher than
the ambient temperature because of the hot
gas stream and the heated adapter. Therefore
a loss of measured components is negligible
because of warm condensate. In case of
DENOX application with a small content of
NH
3
(normally only a few ppm) it is possible to
analyse SO
2
and NOx without great losses (only
some ppm which normally can be neglected).
To determine the loss, it is possible to give
test gas via the probe to the analyser(s).
A measuring fault can be found and cali-
brated.
As an option the vessel can be heated as
well to suppress chemical reactions of the
measured component below a defined tem-
perature.
To the sample outlet of the vessel a heat-
ed sample line 3/4-M for max. 200 °C
operating temperature can be connected.
