This photo was taken May 15, 1977
of vanadium build up on screen tubes at the time a
fuel conditioning system was installed. Note the
vanadium build up that covers the air passage between
tubes restricting heat transfer and increasing excess
air pressure in combustion chamber.

This photo was taken August
16, 1977. Note the removal of vanadium during operation,
increasing heat transfer and reducing excess air pressure.

This photo was taken
September 27, 1977. Note the continued removal of vanadium during
operation. There was no mechanical removal of vanadium during this
time.
