Eclipse Combustion EGA4 - Manual (Page 24)

Instruction Manual MM850481 ed.01
7.4.1 Input of the smoke index
Before input the data, you have to execute the smoke index measurements. You can input up to 3 values; the analyzer
will do the average calculus.
The smoke measurement requires the instrument in normal operating conditions indicating one of the measured or
calculated parameters. Press [SMOKE] on the keyboard. The following page will be shown:
SMOKE
Meas. 1: -
Meas. 2: - AVG
Meas. 3: - -
Oil.Der.: NO

Press [S]and/or [T] to move the cursor symbol to the “Measure 1” input field.
Press [ENTER] to input the value. See instruction on paragraph 8.1.4.
If necessary, input the “Measure 2” and “Measure 3” smoke index. The instrument will compute the average.
Press [S] and/or [T] to move the cursor symbol to the “Oil derivative”.
Press [ENTER] to change the value for the correct fuel type.
Press [ESCAPE] (F1) to return to the previous page without save the changes.
Press [ENTER] to memory store the selection and return to the previous page.
7.5 Combustion air temperature (option)
It is important to measure the true combustion air temperature to have a correct boiler efficiency computation. The EGA4
has a auxiliary Rtd input to measure simultaneously the air temperature. A Pt100 with a 6 meters long cable can be
connected on the right side of the analyzer.
Insert the Rtd inside the air combustion aspiration tube and near the boiler.
Follow the standard procedure to make measurements. The instrument will show the temperature on the display and the
efficiency will be calculated using this value. If no external Rtd is connected, the analyzer will measure the instrument
temperature (ambient) using the internal sensor.
7.6 Flow/Return temperature
Connect the thermocouple type K on the bottom of the instrument (the same connector used for gas temperature). If the
temperature measurement is made using the contact method on the external side of the flow and return water pipe. In
this case, we suggest to use an arch type thermocouple.
