Worn out shaft is built up by welding followed by machining
for required dimensions.
What changes in the design when there is no attemperator?
Without an attemperator, the surface area required in the
furnace will be very huge. Big power plants like 500 MW and 1000 MW do not use
attemperator. Material constraints also necessitate an attemperator.
Advantages of Lovejoy Couplings?
Lovejoy couplings made of rubber
can tolerate misalignment better than other coupling like metaflex (shim type
couplings)
How Magnetic Particle Inspection
(MPI) is carried out ?
Spray magnet particles on the
area to be tested.
Place electromagnet and magnetize
the area. If there is a crack, flux will leak through it and particles will
align themselves along the crack. When seen under UV light, the crack can be
detected.
CPO – Crude Palm Oil
CPKO – Crude Palm Kernel Oil
Application of Seals
Bellow Seal – High Temperature
Liquid places
Unbalanced seal – high face
stresses, closing force is very high
Balanced Seal – Low face stresses
Where the Flushing connection in a seal is ?
Flushing connection in a seal is
always on gland plate
Why Olgone Technology – Lengthens
reformate treater cycles & reduce overall costs.
