12.2 Core flow search
Before using the core flow search it must be switched-ON:
OK.
The core flow search will help you to find the optimal measurement point
in the stack. The core flow can be identified by the maximum flue gas
temperature.
In high reaction time the analyzer displays the trend of the flue gas
temperature. Insert the probe pipe slowly into the stack and position
your probe tube when you have reached the maximum flue gas temperature
that is displayed.
Approaching
the maximal flue gas temperature
Temperature rising
Positioning the probe in the core flow:
Insert the probe pipe slowly into the stack and position your probe pipe
when you have reached the maximum flue gas temperature that is displayed
(see temperature maximum value on the display – in this case 69°C).
Maximum temperature has been reached when the arrows (left picture) disappear,
max. (right picture) appears in place of the arrow, and the
beeper signal stops. Moving away from the max. temperature will result in
the bars moving away from the max. temperature (1 bar is equivalent to
1°C). Once the right core flow has been achieved, the probe is fixed with
the probe cone screw.
