Answer / mohamed elnakib
it is due to the air preheater being clogged increasing the
load of the ID fans due to the bad suction and this clogging
is mostly due to the baskets being melted due to the
formation of the ACIDS from the exhaust gases and the dew
point effect .
this is the only logical reason for why the ID fan is 100%
loaded while the boiler is not .
