PiT Indicator Intelligent
Thermography for indicating temperature and flame variations in their
transient behaviour
PiT VibraSensor Online mill,
classifier and pulverised coal dust pipes analysis by vibration sensors
combined with sophisticated data processing by analysis of correlations
PiT FluxStylus Spatial defined heat radiation flux measurement
PiT Slagging Detector Detect
the amount of slagging at the steam generator walls and at the
super-heater with Powitec's advanced picture analysis tool on
basis of optical information in correlation with temperature
information. Gained information can be used for alarming function.
PiT Reheater Fouling Detection Analyses the amount
of fouling (dust) at the reheater with Powitec's advanced tool on
basis of vibration information analysing changes in vibration in
correlation with temperature information. Gained information can be
used for alarming function
PiT Stabiliser Combination of one or more PiT Indicator with flame scanners and sophisticated software to correlate the analogue outputs with camera signals. Targets: In part load areas increase of the burner and boiler stability (by displaying stability index) and to increase the up-time of the boiler |
