We plan to install a waste heat recovery system (WHR boiler) into the system (with resistance increase about 10 mbar), the ID fan inlet temperature is only 195 degrees (after PH boiler)
the question is, after installing the PH boiler, does the ID fan meet the requirements, is it necessary to replace the fan.
