WebThe modes of operating the unit are named as 1.turbine follow mode and 2.boiler follow mode. 3. Coordinate control system TURBINE FOLLOW In Turbine follow mode Turbine maintains throttle steam pressure. The MW depends on the steam output from the Boiler. The variations in the Boiler steam output will be resulting variations in MW output. WebMay 1, 2009 · There are four usual modes of operation in the world of drum boilers: base mode, boiler-following mode, turbine-following mode, and coordinated control (Table 1).
