Answer Posted / vinoth
when water is converted into steam, huge quantity of
dissolved salts are residues of this conversion. They
normally settle down in the bottom of the Boiler drum. In
CBD, we continuously remove this dissolved salts otherwise
it will get carry over with steam and damage the blades of
turbine. Where as IBD is to remove Excess feed water which
crosses the Seperator level inside the boiler drum.so IBD is
to prevent carry over water with steam where CBD is to
prevent carry over of scales with steam.
with above description, we can easily predict why IBD is
in higher elevated than CBD.
