Boiler Modelling and Optimal Control of Steam Temperature

Abstract: Achieving accurate control of ma in steam temperature is a very difficult task in thermal power plants due to the large process lag (8 to 10 minutes) associated with the superheater system and there exists a deviation of ± 10 ℃ in closed loop control.

Superheated Steam Control System - Shodhganga

A few advantages of superheater are: L Due to installation of superheater thermal efficiency of plant increases. i. It avoids too much condensation of steam in the last stages of turbine due to which erosion of turbine blade is reduced. > It removes the moisture content of steam coming out of boiler and increases its temperatures sufficiently above saturation temperature.
