1.5 ecom-EN3, Option heated probe for soot measurement

Heated probe for soot measurement

In order to perform a measurement of the soot content in the flue gas from oil firing systems,
a filter paper is introduced into the exhaust path of the probe where the soot deposits during
the measurement.

On the basis of the deposited amount of soot on the filter paper (blackening), it is possible to
compare optically with a scale, which is the soot number. This makes it possible to evaluate
the amount of soot in the flue gas.

The filter paper is heated in the probe to prevent the flue gas from cooling too much. This
cooling of the flue gas would lead to condensation of water vapour from the flue gas and will
distort the result of the measurement.

Hint

As an alternative to the heated probe, a hand soot pump can be used. The
possible condensation of water vapour is however not prevented with a hand
soot pump.

Hint

For further information on the procedure for soot measurement with the heated
probe, please refer to chapter "4.7 Soot...Oil trace"

Page 12

ecom-EN3

1.6 ecom-EN3, Option hand soot pump set

Hand soot pump set

In order to perform a soot measurement in the flue gas from oil firing systems, a hand soot
pump can be used.

By a prescribed number of suction strokes with the hand soot pump, a defined amount of flue
gas is drawn through an inserted filter paper. On the basis of the deposited amount of soot
on the filter paper (blackening), it is possible to compare optically with a scale, which is the
soot number. This makes it possible to evaluate the amount of soot in the flue gas.

Hint

The hand soot pump is TÜV tested and characterized by high quality in its
processing and construction. This guarantees a long-term reliable function.

Hint

As an alternative to the hand soot pump, a heated probe can be connected
directly to the measuring instrument. With this heated probe, the possible
condensation of water vapour and thus falsification of the measuring result
can be reliably prevented.

Hint

For further information on the procedure for soot measurement with the hand
soot pump, please refer to the manual for the hand soot pump set.

Gas outlet Gas inlet Level monitoring

Condensate
evacuation

Exhaust gas with a temperature over the steam dew point (35 - 65 °C) is flown spiral via a
long gas path thru a surface coated metal body with good thermal conductivity. The gas
radiates its heat to this metal body. A Peltier element (semi-conductor cooling element) flown
by a continuous current is thermal connected with this body and with a second metal body
with cooling ribs and ventilation slots.
The flow thru the Peltier element creates a heat transfer from WARM to COLD, drains the
heat of the metal body flown by gas and conveys it to the outer cooling body. This heat is
conveyed thru a vertical forced ventilation to the surrounding air.
The condensation issued by the heat loss of the gas drops in a receptacle and is pumped out
on request by a periodically working hose pump.

WARNING

4.1.4 CO-Overload Protection

The CO sensor is protected against overload by the system.

If the limit of 4000 ppm at the CO sensor is exceeded, the internal additional fresh air purging
pump is switched on, which supplies fresh air to the CO sensor.

When the CO overload protection is active, the CO indicator flashes in the status bar of the
measurement screen, and the <Info> status LED changes from "green" to "red".

If the opening for the supply of fresh air to the CO sensor is closed, the
sensor can not be purged with fresh air and will be damaged or destroyed
during overload.

Fresh air opening

If the CO sensor has been purged sufficiently with fresh air (X disappears behind CO) and
the measured values are within the permissible range, the fresh air flushing pump is switched
off.

The CO indicator in the status bar of the measurement screen no longer flashes and the
status LED <Info> changes from "red" to "green".

Hint

The "CO automatic" option can be used to set how the fresh air flushing pump is
switched off after sufficient purging of the CO sensor:

- automatically

- must be triggered manually

4.2 Measurement procedure gas analysis: CO measurement

The gas channel check, called also CO measurement, is used for the technical check of gas­fired plants in regards of safety aspects. Hereby the CO concentration in the gas channel is
measured after the flow safety device and calculated on an undiluted value (oxygen rest
content in flue gas = 0%). As the gas conditions after the flow safety device are no more
homogeneous because of the flow in of secondary air and consequently the core stream
measurement can be erratic, the analysis of the exhaust gas is performed along the totality of
the exhaust pipe diameter. A multi-hole probe (optional accessory) is hereby used as
sampling probe.

The calculated value shown on the line „CO 0 %“ corresponds to the measured CO
concentration supposed the oxygen content would amount 0% by the same exhaust gas
volume. It is consequently the undiluted CO content in exhaust gas. If the values indication is
stable, press <Record> to store the result in the intermediate memory. If a printout of the
values should occur simultaneously to the recording in the intermediate memory press <F2>
(the complete content of the intermediate memory will be printed out).

1

Measurement stored in intermediate memory

4.3 Measurement procedure gas analysis: O2 Check

This measurement is performed by room-independent plants like gross calorific value plants.
It is determined if exhaust gas flows into the combustion air (O2 content drops down / CO
content can be present) and herewith influence on the combustion quality. For this analysis,
a special multi-hole probe (optional accessory) should be used. If the value indicated is
stable, press <Save> to store the value in the intermediate memory. If a printout of the values
should occur simultaneously to the recording in the intermediate memory, press <F2> (the
complete content of the intermediate memory will be printed out).

4.4 Measurement procedure gas analysis: Draught measurement

1

A trend indication for the draught conditions in the exhaust channel can already be viewed
during the gas analysis. Nevertheless the value for the chimney draught will not be stored
together with the gas values while pressing <Save> because the differential pressure sensor
tends to drifts because of its sensibility. For an exact measurement, it is consequently

production, distribution and transfer) from the energetic point of view. Hereby the single plant
components get inspected by the heating engineer in a combination of measurements and
visual assessment and valued in regards of their energetic quality acc. to a negative point
system of maximum 100 points. The higher the score, the farer the current plant is away from
the desirable energetic stand and the higher the energy saving potential would be if
modernization measures are conducted. In combination with the special probes required
hereto, the ecom-EN3 is able to perform the measurement of the heating check parameters:
gas losses, ventilation losses and surface losses. Out of the main menu point "Diagnostics",
select the sub-menu "Heating Check" and confirm with <Enter>.

The gas losses measurement is to be performed with the

instrument´s sampling probe in the gas core stream after
menu call up. Once the measurement is recorded with

11. Maintenance Tips

To secure the accuracy of your measuring instrument we recommend the annual check by an
authorized ecom partner.

WARNING If sensors from other manufacturers are used, the TüV approval of the

instrument expires.



Use only sensors from ecom or from an ecom authorized service

centre.

WARNING Service made by service centres non-authorised by ecom GmbH will result in a

complete and immediate loss of any warranty!



authorized service centre.

Have service work performed only by ecom or by ecom

Hint

In the case of strong use (e.g. permanent several hours of measurement per
day, rough conditions etc.) shorter intervals between checks should be
selected.



Please contact your ecom partner. All ecom partners are listed

under www.ecom.de.

The following components should be checked every time the instrument is used:

11.1 Fine dust filter

Procedure for testing:

ecom-EN3

1. Unscrew the cap.

2. Check the condition of the particle filter.

3. Replace the cap.

Hint

Change the fine dust filter once the filter has a grey colour.



Replace the fine dust filter if the filter has a gray colour of 2 ... 3 on

the soot comparison scale.

Page 63

11.2 Gas sensors

The sensors get calibrated with the reference gas fresh air by each switch-on.
New sensors age along the operation time because of the wearing of the reagents (oxygen
sensor) and due to soiling respectively exceeding concentrations beyond the nominal
measurement range (toxic sensors).

Their state of the sensors is permanently checked by the instrument.
The output values of the sensors are listed in the menu "Control". The reference values of
the sensors are:

Sensor Reference value output voltage

O2 12000 mV

Others 0 mV (+/- 150 mV)

Hint

If an error message occurs during the calibration phase, a further calibration
phase can help to calibrate all installed sensors sufficiently.



If after several repetitions of the calibration phase an error message

occurs during the calibration phase, the instrument has to be checked.

Hint

The O2 sensor must display a value > 7000 mV.



If an output voltage <7000 mV is displayed in the "Control" menu

after the calibration phase, the O

sensor must be replaced.

2

Hint

The CO sensor is protected against overload by the internal programme.



For further information on CO overload protection, please refer to

the chapter "CO-Overload Protection"

11.3 Probe and tubing

Depending on the frequency of use, probe and tubing should be regularly cleaned in order to
release particle deposits and to prevent early wearing due to corrosion.

The hose can be cleaned (flow warm water in then dry respectively blow water drops out)
after loosening all plug-in connections on the instrument and on the probe.
O-rings of the hose connections should occasionally be greased with acid-free grease.
