"Heat exchangers that transfer energy from flue gas to steam are important units of thermal power stations. Their inertias are often decisive for the design of the steam temperature control system. In this paper, the analysis and the simulation of the dynamics of the steam superheater are discussed. Superheater is simulated as a unit of a control loop that generates steam of desired state values. To simulate the steam superheater on the computer, the exchanger is described by the set of partial differential equations. The equations are then solved numerically by modified finite difference method. Discussion of method and qualitative and quantitative results are presented. Paper describes use of Simulink S-functions which make it possible to set-up the most complex systems with complicated dynamics. There's a comparison of M and C S-functions, which are two main approaches when building user-defined blocks in Simulink, regarding both the performance and the efficiency of the simulation for M and C" .
