AUTOMAÇÃO DO CONTROLE DE NÍVEL DE ÁGUA DA CALDEIRA

Abstract

Steam generation was one of the great milestones in human history, due to industrial revolution, but as boilers were very rustic and their control was totally manual and mechanical, or which cause operational accidents. With the advance of technology both in materials and process controls as boilers have reached levels increasingly automated, following that the market always demands more and more its Providers. Currently, the boilers have a system of controls fully automated as a case of water level that will be our study in this work, where we will focus on explaining the existing level control types, the level concept and some function blocks that will be required to program a programmable logic driver (CLP). For the development of boiler level automation, we will create a scheme a graphical program (ladder) to control the PLC and finally the creation of a human machine interface (HMI) program.
