Avaliação das oportunidades de conservação e gerenciamento de energia em sistemas de geração e distribuição de vapor - estudo de caso Tongaat-Hullett : Açucareira de Moçambique

Abstract

The sugar production industry faces significant challenges regarding energy efficiency, particularly in the use and management of steam. This study aims to evaluate the opportunities for energy conservation and management in the steam generation and distribution system at Tongaat- Hulett: Sugar Mill of Mozambique, located in the Sofala province. The analysis is based on the premise that a substantial portion of the energy used in industrial production is wasted as residual heat in various points of the production process. The objective of the study is to analyze the energy efficiency of the boilers and the steam line, obtaining quantitative values of energy losses as a basis for conservation and management solutions. The analysis revealed that the energy efficiency of the boiler can be improved through optimized fuel use and adequate thermal insulation of systematic energy audit programs and continuous improvements in steam generation and distribution system are essential to reduce energy losses and enhance efficiency. Adopting optimized pipe diameters and better insulation can significantly reduce energy waste and operational costs.
