Dear Mr Paul,
The cyclone separator is in the main gas line which enters our complex. It
is necessary to remove these dust particles as the gas enters to Gas
trubines and Process stream further. The purging frequency depends on
quality of supplied gas. These days the purging is necessary to be operated
to remove the dust at least twice in a 8 hour shift.
To provide more clarity, the arrangement is as below:
The valve is located just at the bottom of the cyclone separator (which
separates dust from gas). We have provided double valve(4" Plug-metal seated
and lubricated) to take care of these operations, One always kept open
other used for operation, but still end up both passing. Presently we need
to inject the lubricant frequntly to arrest this passing. It is not
practical to inject the sealant everyday. Hope the elite group here helps
out.
Just a thought .. that if the type of valve used is right, then, comes
addressing the quality of the manufacture too..
with regards,
