Optimización de equipos térmicos y termodinámicos con enfoque mecatrónico.

Abstract

Steam generators are equipment of great demand and use in the industrial sector. However, they have a high fuel consumption that has an impact on an unsustainable use of fossil resources. The objective of this work is the optimization of a 100 BHP fire tube Diesel steam generator using a mechatronic approach. To do this, he developed a mathematical model represented in state space; the model was simulated using open and closed loop control determining the best option in each process; the system was evaluated by varying different parameters in order to obtain those that optimize energy and exergetic efficiency and analyze their sensitivity. The parameters evaluated were the number of smoke tubes, type and thickness of the insulator in the tabor, temperature of the feed water and the disturbance of the ambient temperature. It was obtained as a result of the simulations that for the processes of initial heating to saturation and heating to the operating temperature it is better to use an open loop control, while in the operation process the use of a closed loop control is better. As a result of parametric optimization, energy and exergetic efficiency increased by 10.57% and 8.44% compared to the initial model. The most sensitive parameter is the water supply temperature, increasing energy efficiency by 11.57% for each degree Celsius, followed by the number of smoke tubes and the thickness of the insulator
