Análise comparativa da eficiência energética de sistemas de aquecimento térmico e elétrico para vasos e tubulações em ambientes industriais

Abstract

The issue of energy efficiency is becoming more popular day in Brazil, however the initiatives has proved timid, when we observe the few pro active attitudes of the industrial sector, and this is the leading sector in energy consumption in the country. As a result, this paper presents two proposals applicable in industry for heating pipes and vessels, the proposals compare the steam heating technologies versus electric heating. Overlooking the energy efficiency of processes is important to evaluate the applications from the economic point of view, technical (practicality and operability) and environmental. The methodology used for the comparison of systems, includes a preliminary study by the theoretical framework, then, using a case study, the main established comparison parameters is verified and it is concluded presenting the pros and cons of each technology taking the best application for each case.
