Common Steam Boiler Challenges

Control Engineering | Power Control: Advanced

Each boiler has two forced draft (FD) fans situated on the left and right side at the rear end of the boiler. The FD dampers control the forced draft into the boiler and are used to regulate the furnace pressure. The flue of each boiler is equipped with an oxygen analyzer and induced draft (ID) fan that controls the boiler steam pressure.
