CO Boiler Convection Replacement
Our client Refinery had a CO Boiler in their Catalytic Cracking Unit. The CO Boiler was more than 40 years old. The CO Boiler convection section is used to preheat the FCC charge and also generate superheated steam at 600 psig/710°F.
The Boiler had problems of low economizer tube metal temperature reaching dew point levels and high superheated steam temperature. There were also problems with the tube supports in the hottest zone. CO Boiler Convection Section Replacement
