Bacharach 24-7224 User manual

Introduction
The Bacharach Flue-Gas Sample Conditioning System consists of the
following components:
• Probe with Peltier Cooler
• Condensate Pump with Water Trap
• Power Supply
The function of this system is to remove water vapor from the ue-gas
sample, thus preventing the formation of water droplets inside the
probe hose. If water droplets were to form inside the hose, a portion of
the gas sample could be absorbed by the water, thus resulting in lower-
than-actual readings of NO2and SO2.
Water vapor is removed from the ue-gas sample by passing the sample
through a Peltier Cooler where the sample is chilled, which in turn,
causes the water vapor contained in the gas sample to be removed from
the sample.
The water that was extracted from the gas sample is then pumped out
of the Peltier Cooler and into a water trap.
The now dry, conditioned ue-gas sample is then sent to its associated
combustion test equipment for analysis.

Equipment Setup
Refer to Figure 2. If not already done, attach the Peltier cooler to the
probe assembly by rst removing the plastic end cap from the rear of
the probe, and then inserting the cooler’s inlet connector, ensuring rst
that a lter is present between the cooler and probe.
Attach the pump’s inlet hose to the bottom of the Peltier cooler. Water
that is condensed from the ue-gas sample will be pumped into the con-
densate pump’s reservoir through this hose. Note that the condensate
pump can be placed in an upright, horizontal, or hanging position. A
magnet mounted in the base of the pump allows the pump to be at-
tached to overhead ductwork.
Connect the power supply’s DC output connector to the condensate
pump; then connect the condensate pump’s DC output power connector
to the Peltier cooler. The Peltier cooler and its associated condensate
pump are started by plugging the power supply into a source of AC
power that is between 100 and 240 VAC, 50/60 Hz.
Connect the probe assembly’s stack-temperature thermocouple con-
nector, pressure tting, and ue-gas tting to the combustion analyzer
per the analyzer’s instruction manual.

Operation
When ready to conduct a combustion efciency test, plug in the power
supply of the Flue-Gas Sample Conditioning System. You should hear
the condensate pump start running and see the Peltier cooler’s red LED
turn on and off as the cooler is cycled. Note that the cooler’s operating
time changes according to its temperature.
Set up and congure the combustion analyzer as described in its in-
struction manual. Then insert the probe into the ue stack and begin
testing.
During the combustion test, the condensed water vapor from the ue
gas will accumulate inside the pump’s reservoir. If the water level be-
gins to approach the ends of the tubes inside the reservoir, then stop the
test and empty the reservoir as described in the Maintenance Section of
this manual.
WARNING! The probe tube is hot! In the following step, be
sure to allow the probe tube sufcient time to cool before
handling.
At the conclusion of the combustion test, remove the probe from the
stack; then unplug the Peltier cooler’s power supply.

Maintenance
Probe
The probe’s sponge-type lter (Figure 3, Item 9) needs to be inspected at
regular intervals for dirt contamination. Replace lter as necessary by
rst pulling out the Peltier cooler from the probe and then exchanging
the lter with a new one.
Peltier Cooler
The cooler’s wadding lter (Figure 3, Item 12) needs to be inspected at
regular intervals for dirt contamination. Replace lter as necessary by
rst pulling off the lter chamber’s top cap and then exchanging the
lter with a new one.
Condensate Pump
WARNING! The condensed water will be warm and slightly
acidic. Take all necessary precautions to prevent the water
from splashing into your eyes or contacting your skin.
Empty the pump’s reservoir (Figure 3, Item 15) by rst holding the
pump with its reservoir facing downwards. Then twist the reservoir 90
degrees (either clockwise or counterclockwise) to free it from the pump
base. Empty the reservoir; then reattach it to the pump. Before reat-
taching the reservoir, however, make sure that the reservoir’s o-ring
(Figure 3, Item 20) is properly positioned inside its grove in the pump
base.
The pump’s wadding lter (Figure 3, Item 17) needs to be inspected at
regular intervals for dirt contamination. Replace lter as necessary by
rst unscrewing the lter chamber cap and then exchanging the lter
with a new one.
