Economia de energia elétrica de um sistema de bombeamento tipicamente industrial

Abstract

It is known that, in the industrial environment, electricity consumption corresponds to a high share of annual expenses. Therefore, a study that optimizes the industrial process, reducing electricity costs, is extremely important. In this scenario, this work will have as main objective the realization of a financial analysis of the exchange of a pumping system driven by an IR1 engine (standard or conventional line) and operating with flow control via throttle valves, for a pumping system driven by an IR2 motor (high performance) that controls the flow through frequency converters. This financial analysis takes into account the cost of all new equipment to be purchased, the annual savings generated by the replacement of the systems, as well as the useful life of each equipment used. For this, the analysis was made for two cases: First, for a hypothetical case, and later, another analysis for real engines and equipment available at the Energy Efficiency Laboratory of the Federal University of Uberlândia (LEFE-UFU). The results obtained were satisfactory, since they indicated an annual savings of up to 60% of the electric bill. Therefore, once again the importance of this work is emphasized, because, in addition to presenting a great opportunity for saving the industrial process, it also has a sustainable bias, since the proposed system presents less energy consumption.
