To perform complete flue gas analysis, follow the instructions below.
14.1.1 Switching on the instrument and auto-calibration
Press the On/Off key to switch on the instrument - an introductory screen will appear. After a couple of moments
the instrument will zero itself.
The pressure sensor is also zero enduring the autozero process.
14.1.2 Inserting the probe inside the stack
When auto-calibration is complete the instrument will instruct the user to insert in the chimney the sample probe
that has been previously connected to the relative input on the instrument, and the analysis screen will appear
automatically.
SOME IMPORTANT WARNINGS TO CONSIDER DURING THE COMBUSTION ANALYSIS
ARE LISTED BELOW:
FOR A CORRECT ANALYSIS NO AIR MUST FLOW INTO THE PIPE FROM OUTSIDE DUE
TO A BAD TIGHTENING OF THE CONE OR A LEAK IN THE PIPELINE.
THE GAS PIPE MUST BE CHECKED IN ORDER TO AVOID ANY LEAKAGES OR OBSTRUCTIONS ALONG
THE PATH.
THE CONNECTORS OF THE GAS SAMPLING PROBE AND OF THE CONDENSATE FILTER MUST BE
WELL CONNECTED TO THE INSTRUMENT.
KEEP THE CONDENSATE TRAP IN THE VERTICAL POSITION DURING THE ANALYSIS; A WRONG
POSITIONING MAY CAUSE CONDENSATE INFILTRATIONS IN THE INSTRUMENT AND THUS DAMAGE
THE SENSORS.
DO NOT PERFORM ANY MEASUREMENT WHEN THE FILTER IS REMOVED OR DIRTY IN ORDER TO
AVOID ANY RISK OF IRREVERSIBLE DAMAGES ON SENSORS.
14.0 FLUE GAS ANALYSIS
14.1 FLUE GAS ANALYSIS
DURING INSTRUMENT AUTOZERO, THE SAMPLING PROBE MUST NOT BE INSERTED IN
THE CHIMNEY.
IT IS IMPORTANT THAT THE SAMPLE PROBE IS NOT INSIDE THE CHIMNEY SINCE
DURING AUTOZERO PROCESS THE INSTRUMENT DRAWS FRESH AIR FROM TH E
ENVIRONMENT AND DETECTS THE ZERO VALUE OF SENSORS (O
2
, CO, NO, ..) THE DETAILS OF
WHICH ARE THEN SAVED AND USED FOR REFERENCE DURING THE ANALYSIS. IT IS EQUALLY
IMPORTANT THAT THIS PHASE IS PERFORMED IN A FRESH-AIR ENVIRONMENT.
