Thermodynamics, thermoeconomic and economic analysis of sugarcane biomass use for electricity production: A case study
AbstractThis work allows the thermodynamics, thermoeconomic and economic analysis of the cogeneration system of an industrial plant. Two settings were studied: the current that produces electricity only for its own, and secondary, a plant working at high pressure and high temperature using extraction steam turbines to drive an electricity generator and produce 32 MW and a backpressure turbine capable of producing 12 MW. In this case, a high investment is necessary and therefore, a considerable amount of energy sales. The thermodynamic analyses allow the evaluation of some performance indices. The thermoeconomic analysis proposes the distribution of costs based on thermodynamic concepts, enabling the evaluation of reflection of the investment costs and fuel in the cost of products (steam and electricity). The economic analysis acts as a deciding factor for acceptance or project rejection.
