Hello,
My question is related to the pulse cleaning of turbine/generator inlet air filters. Our machine uses pulse cleaning with Dwyer control. In the dwyer dp gauge there are three pointers. One for actual dp across the inlet filters and 2 others for preset dp and high set dp.
I want to know how the preset dp and high set dp are used in the pulse cleaning process? Is the preset dp, the dp above which the pulse cleaning timer starts and stops when the actual dp reaches below it? Is the high set dp value used to over-ride the timer based cleaning? In manual cleaning mode, how does the reverse purging of filter continues?
What are the typical values of pre set and high set dp in dwyer gauge? Ours is a frame 6 gas turbine of 30 MW capacity.
