A super heater is a device that is used to convert wet, saturated steam into dry steam. Dry steam at 538°C contains more thermal energy. It increases the overall efficiency of the cycle. The Modelling of the Super heater is done to control the temperature. The paper deals with simulation of control of power plant Super heaters by means of Simulink. The simulation models are developed. These are applied to electrical power generating plants in order to characterize the essential dynamic behaviour of the boiler. The corresponding models are used for the power plant processes. Mathematical model of a super heater is described by sets of nonlinear partial differential equations. Estimation of the Super heater model is done by the System identification tool for design of a steam temperature control system. Data obtained by the measurement compared with simulation results.
