Dear Henrik,      We have followed the nozzle loading given by you for all the nozzles of Preheater. But there is problem with load w.r.t 400 NB nozzle (N3 & N5). The 400 NB nozzle is not taking the specified load.  Instead, we checked that 400 NB nozzle is able to take a load that corresponds to 125 NB nozzle in the table.  Please confirm whether this load consideration is OK for you.   If you still want the higher load to be considered than that then you are requested to provide bellow in the pipelines.  Please confirm
