SUBPRESSURE
The pressure in the boiler is constantly maintained at a lower pressure than atmospheric
pressure in the vicinity of the boiler. Differential pressure transducer measures the difference of
pressure in the boiler and boiler environment and based on that information adjusts the fan speed
of flue gases through the frequency converter. At various stages of the work the different
subpressures in the boiler are required. At the first of two displays under VACCUM there are
information about the current subpressure in the boiler, the required subpressure, current fan
speed of flue gases (in percent) and the current rate of primary air fan (in percent).
At the next display the values of the subpressures in phase of the boiler operation and its rest are
set. Here you can define the minimum and maximum fan speed of flue gases (in percent).
