Proposta de um programa de manutenção para caldeira flamotubular: caldeira da Sumol + Compal

Abstract

Maintenance is the process of keeping equipment available, efficient and in safe condition at the lowest cost. This work aims to improve the maintenance program of a fire tube boiler in a beverage factory. It was developed in the context of a professional internship, where several opportunities for improvement were identified for the maintenance department. The factory is divided into two main areas: utilities and production. The process of obtaining the final product involves various inputs, and the utilities provide inputs for the production lines themselves. Utility systems include the production of steam, electricity, water supply, compressed air, etc. The machine responsible for producing steam is called the boiler. In beverage factories, the boiler is a highly critical piece of equipment, as the steam it produces will feed various pieces of equipment in the production area, including pasteurizers, which are responsible for eliminating bacteria from the beverage. This great responsibility of the boiler to produce steam and the various observations made that made the maintenance of the boiler very poor, which led to serious consequences ranging from the total stoppage of production at the plant to the risk of explosion, were the reasons for carrying out this work. The work explains the concept of maintenance and its types, in which reliability-focused maintenance is recommended for the boiler, in order to record and analyze anomalies and from the results of their analysis update the maintenance plan annually, which in turn will first be drawn up by compiling the manufacturer's recommendations and the experiences of the maintenance technicians. This maintenance plan makes up a list of tasks to be implemented periodically and is also accompanied by the RCM strategy, which proposes the stages of its implementation.
