DescriptionIn this work was made the simulation of the thermal cycle of São Jerônimo - UTSJ thermal power plant. The power plant, very old, has a grate boiler. In the same power plant was installed an experimental fluidized bed boiler, workingin parallel with the existing one. The work starts with the modeling of a simple Rankine cycle and evolves up to establish the most suitable and representative configuration to simulate the mode the work of São Jerônimo –UTSJ thermal power plant. Therefore, in this work it was adopted the more conventional considerations in the design practice for thermal power plants whose systems are based on the Rankine cycle. The simulations, which are characterized by the simultaneous solving of equations that model the cycle and its components, were made through the IPSE-pro® software. The simulations were applied to obtain the main results on the analysis of thermal systems such as, thermal efficiency of the cycle, power, system mass flow, heat exchanged in the steam generator and condenser, among others. Finally, in order to improve the thermal efficiency of the plant, some alternatives to the actual system were presented.
