1.1 FUNDAMENTALS

Gas flow

A built-in sampling pump is drawing the flue gas through the gas-sampling probe into the
analyzer.

1. The gas flows through the gas-sampling probe to the condensation trap.

2. Then the gas passes through a particle filter where dust particles are removed.

3. Then the gas enters the sensor chamber.

Gas temperature

The gas temperature is measured by a thermocouple located at the tip of the gas-sampling
probe.

Electrochemical sensors

Each electrochemical sensor measures the concentration of a specific gas.
Electrochemical sensors can be damaged

- if exposed to small particles - never measure without a dust filter

- if water / condensation comes in contact with the sensors - empty condensation

trap

Service / Calibration

A “Service” message will be displayed after 1000 hours or after one year of operating time.
IMR Environmental Equipment, Inc. recommends checking the calibration once a year.

Operating Temperature

50oF..104oF / 10oC..40oC
If the unit is brought in from the cold, then it should be allowed to warm up for a few minutes.

Storage Procedures: IMPORTANT!

Storage Temperature

-4oF..122oF / -2oC..50oC
When not in use or in storage, please make sure to keep the analyzer plugged into a wall outlet
(AC).
This ensures that the analyzer maintains a constant battery charge and function properly if
needed.
Prolonged periods of disuse without charging the battery may result in a weak battery and the
battery can lose its ability to hold the charge.

2.4 SYSTEM CONNECTIONS

2.4.1 Probe

The gas-sampling probe plug and hose has to be connected to the analyzer before it can be
turned on and must stay connected during the whole measurement.
If the gas-sampling probe is not connected, then the analyzer cannot perform an accurate
calibration and an error message will be displayed.

Type S (if equipped with soot measurement)

The probe S has two hoses. One for the flue gas measurement and one for the draft
measurement. Both hoses must be connected to their fittings at all time.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple - Connect the thermocouple plug (5-pos) with the
'flue gas temp' socket of the analyzer

b) Flue gas - Connect the hose, which has the condensation trap
inline to the barbed fitting 'gas input'

c) Draft - Connect the second hose to the barbed fitting
'draft'

Type E

The probe E has one hose for the flue gas measurement and the draft measurement.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple - Connect the thermocouple plug (5-pos) with the
'flue gas temp' socket of the analyzer

b) Flue gas - Connect the hose to the barbed fitting 'gas input'

The hose must be connected to the 'gas input' fitting for the flue gas measurement.
The hose must be connected to the 'draft' fitting only for the draft measurement and it must be
connected back to the 'gas input' fitting after the draft measurement is completed.

Type C (if equipped)

The probe C is a ceramic probe with a Pt-RhPt thermocouple and it is used for high
temperatures. The temperature range is 302F-2732F / 150C-1500C.
It has the same connections as the probe E.

4 CALCULATIONS

The IMR 2800 calculates most parameters that are important for the measurement of a
combustion process:

- Heat losses

- Excess Air

- Carbon dioxide CO2

- mg/m3, mg/m3 (Ref.O2)

- NOx (NO+NO2)

4.1 EXCESS AIR

In reality it is not possible to achieve a perfect combustion using the theoretically required
amount of air. Therefore excess air is needed.
The ratio of the volume of air to the volume of air theoretically required is excess air.

The excess air value must be kept low, as it needs to be heated resulting in a decrease of the
flame temperature and an increase of the flue gas temperature, thereby deteriorating the
efficiency.

4.2 CARBON DIOXIDE CO2

The CO2 percentage in flue gases depends upon the amount of carbon contained in the fuel. In
order to achieve an optimum combustion a small CO value and a maximum CO2 value must
be set (ideally the entire carbon is converted into CO2).

CO2max = max. CO2 of the fuel

The flue gas CO content that results from incomplete combustion is to be kept as small as
possible because of its toxicity. In addition this CO content takes up latent heat, which results
in higher flue gas losses.

4.3 HEAT LOSSES

Complete utilization of heat emitted during the combustion process is desirable, as is a very
small heat loss of flue gases. The loss of free heat is caused by the temperature difference
between the fuel air mixture entering the furnace and gases evolved. The larger the amount of
excess air and thereby the volume of flue gas and the higher the flue gas temperature the
higher the losses and smaller the combustion efficiency.

BImSchV - calculation

The BImSchV-calculation is used for the fuels below.

qA = Losses in %
tA = Flue gas temperature in oC
tL = Air temperature in oC
O2 = Oxygen in %

Siegert Calculation

The Siegert formula is used for all other fuels (see table below) and for the programmable
fuels.

- Heat loss due to free heat (qAf)

- Heat loss due to latent heat (qAg)

LOSS DUE TO FREE HEAT qAf

qAf: Flue gas loss due to free heat
tA: Flue gas temperature
tL: Air temperature
CO2: Carbon dioxide content
f: Fuel coefficient according to Siegert

The fuel coefficient factor depends on the fuel type (composition), the flue gas volume, and
the air number value.

LOSS DUE TO LATENT HEAT qAg
This is caused by incomplete combustion, when the flue gases contain CO portions. It is
calculated as follows:

qAg: Flue gas loss due to latent heat
a: Fuel factor
a = 32: natural gas
48 : fuel oil

The incomplete combustion of fuel oil results in further losses due to soot and oil coke
formation, the deposits of which cause insulation on the heating surface and an increase of
flue gas temperature.

LOSSES DUE TO HEAT RADIATION
The radiation loss depends upon the design and insulation of the boiler. In general, it is
between 0.5 and 3%.

To determine the total loss of the boiler, the radiation loss must be subtracted from the
combustion efficiency.

4.4 CONVERTING PPM INTO VOLUME/WEIGHT RATIO

The conversion of ppm values into mg/m3 (milligram per cubic meter) is based on the
following conversion factors (referred to 0C / 32F gas temperature):

3

SO2  1 ppm = 2.86 mg/m

NO  1 ppm = 1.34 mg/m

3

NO2  1 ppm = 2.05 mg/m3

If the selection "NO(x) as vol. NO2" is activated, then the conversion for NO or NO(x) is:

NO(x)  1 ppm = 2.05 mg/m3

4.5 CONVERTING PPM INTO VOLUME/WEIGHT RATIO WITH REF. O2

EB = (20.9 - O2B) / (20.9 - O2M) * EM

EB: Emission with reference to the oxygen content
EM: Measured emission in mg/m3
O2M: Measured oxygen content (%)
O2B: Content of reference oxygen (%)

4.6 NOx (NO+NO2)

If the analyzer has a NO and a NO2 sensor, then the NOx value is calculated as following:

NOx = NO + NO2

NOx in ppm
NO: measured NO value in ppm
NO2: measured NO2 value in ppm
