Modelagem e simulação dinâmica de uma caldeira industrial aquatubular utilizando o Simulink

Abstract

This work addresses the development of a physical, mathematical and computational model of a steam generation process using a large-scale industrial boiler. Initially, a brief contextualization is presented about the challenges of testing industrial processes, motivation of the work. Then, the physical characteristics of the modeled process are presented, as well as the differential equations that represent these characteristics. The state space equation approach is used to build the simulator programmed in the MATLAB®-SIMULINK® environment, through an User-Defined Functions library resource. Finally, control loops traditionally found in industrial processes are incorporated and analyses are realized to check the stability and dynamic response of the built model. Developed with support of the company Aimirim, an engineering consultancy that works in the development and implementation of solutions for industry 4.0, the validation of the model is carried out through the comparative analysis of the response obtained in simulations based on real conditions found in industrial boilers.
