Approximately I need a reduction of 20% of heat transfer or alternatively a reduction of effective surface of same amount.
Unfortunately superheater geometry does not allow any kind of mak good (like as tubes removal or flue gas bypass).
Material of tubes is A-213 T11.
Thanks.

Doug,
you're right.
In my case superheater bank is splitted in two sections: primary and final with intermediate desuperheater to control steam temperature at final superheater outlet.
During design phase i "overdesign" super heater surface to take into account boiler operation at minimum...
I'm am a boiler engineer.
I have one boiler currently in commissionig phase.
since beginning I have noticed that superheater bundle installed surface is too much and steam temperature exceed design limit.
Is ther any possibility to carry out a sort of artificial fouling (like as some coatings ...
