Modelación matemática de un Ciclo Orgánico de Rankine Híbrido con energía solar para el aprovechamiento del calor residual del Horno B&T de la Empresa Ecuacerámica S.A.

Abstract

This research aims to develop a mathematical model of an organic cycle Hybrid activated renewable energies (solar energy) and residual heat from the B&T furnace of the Company Ecuacerámica S.A. (cogeneration). For the modeling, Parabolic cylindrical solar collectors were used, optimal technology in this type of design, with a thermal storage tank that feed together with the cogeneration heat recuperator to the cycle evaporator, in which by the flow important energy that is available, it is designed with a regenerator to improve thermal efficiency. The system is designed so that maximum electricity production is generated with the greatest exploitation of residual heat available from the company's furnace and a collector area of 600 m2. The examinated model is investigated in steady state conditions with a thermodynamic model developed in EES (Engineering Equation Solver) DEMO version, comparing 5 working fluids: Toluene, Cyclohexane, n-Pentane, Isopentane and octamethyltrisiloxane (MDM), obtaining maximum electricity production with Toluene that reached 79.31 KW and an efficiency of 20.52% with the temperature of the residual heat source of 176 ° C and the use of 47 solar panels.
