Thermal Power Plant - Components, Working and Site Selection

The boiler is used to produce high-pressure steam. The boiler in the thermal power plant is used to convert the chemical energy of coal into thermal energy or heat energy. During the combustion of coal, a high temperature is produced inside the boiler. This temperature is high enough to convert water into steam.

Boiler Follow Mode and Turbine Follow Mode and Co

Apr 29, 2017 · In boiler follow mode, the boiler parameters are set as reference and output of boiler is used to produce power from turbine. Generally the boiler operates near maximum operating capacity, thus inlet pressure at the turbine varies as at boiler outlet. Thus the turbine output will vary as per the boiler parameters i.e. the turbine inlet pressure
