Model in absolute units of the air preheater for operation simulation of high power steam generator

The paper presents the importance of the steam generator in the operation of power plants, stressing the importance of their management and automation to increase energy efficiency of each link in the chain. It presents mathematical model in absolute units from the air preheater. Modelling is based on physical model of the air preheater steam generator, simplifying assumptions adopted and the conservation equation of energy. The block diagrams are presented variation curves obtained and output data. The theoretical model proposed is implemented in Matlab-Simulink obtained simulations for the air preheater in dynamic regime.
