Abstract
The Cooling Tower plays a fundamental role in the operation of a coal-based thermoelectric plant, since it is one of the systems responsible for the thermodynamic balance of the plant. Therefore, for a proper maintenance plan to be developed for the cooling tower, it is necessary to carry out a qualitative and quantitative study of the reliability of this system. This paper proposes the development of a reliability analysis based on Stochastic Petri Nets for the Cooling Tower. Initially, a study of the system is done through the techniques of Functional Tree and Functional Description. Then, a qualitative analysis of the system reliability is performed through Failure Modes and Effects Analysis (FMEA). Finally, the quantitative analysis is done through Stochastic Petri nets, with the support of the Block Diagram technique. For this, the Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR) of each component of the system will be taken into account.
