Aumento de eficiência energética de uma instalação de geração de vapor por meio do reaproveitamento de energia em linhas de retorno de condensado

Abstract

The present work was developed in a system of generation, distribution and use of thermal energy in the form of steam, to increase the energy efficiency of a process plant in the interior of the State of Minas Gerais. For this, a previous study was carried out to verify the amount of flash vapor eliminated before the implementation of a new system, in which part of the condensate produced by indirect use of steam of the whole factory was lost. After the analysis of the initial design, the relevant modifications were made, reusing by complete the condensate from the indirect use of steam of the whole industrial plant, to reduce the amount of fuel used in the steam generator. Finally, a quantitative analysis of energy and financial resources was carried out to verify the efficiency of implementation of the new process, which currently works in the plant in question.
