In this work, thermodynamic and thermoeconomic analyses of a plant resulted from an expansion of the Pioneiros Distillery's cogeneration system are carried out, which is constituted basically by a boiler that produces 140 ton/h of steam at high pressure and temperature (6,6 MPa and 530 ºC, respectively), by a condensation-extraction turbine that drives a electrical generator producing 32 MW, being the mechanical drivers realized by electrical engines. By means of thermodynamic analyses it's possible to define some plant's performance indexes as well as evaluate the global use of energy in each component. The thermoeconomic analysis allows evaluating the costs of capital and fuel reflexes in the composition of the products (steam and electricity) costs.
