Hello there,
Air Inlet Filter house is installed in Gas Turbine units to filter the inlet air.
The differential pressure across the filters is monitored continuously and an alarm and Trip is generated based on these readings thru MARK VIe.
There is a whole lot of mechanism to continuously clean the filters as well. That is achieved thru SOV Pulse mechanism. A sequencer card gives pulse signal to SOVs and a vibration is generated in the filter lines which sort of shakes the filters and dust them...!!!
Now, my question is, couldn't this sequencer card and PDILSH switch be done away with entirely and take the entire control in MARK VIe. I mean, why is there a need to maintain a separate control panel for this when MARK VIe is capable of handling entire GT as well as boiler.
Waiting for all of yours valuable inputs...
Thanks and regards
