RESUMO

This work analyzes the technical, economical and financial viability to substitute the resistive electrotherm for the direct combustion of fuel gases, such as natural gas (NG) and liquefied gas of petroleum (LGP). In order to do so, a study of the electrotherm presence in the productive process of some industries located in The Great São Paulo has been done; a methodology to choose industries concentrated mainly in the above mentioned geographic region by Zip Code, ISIC Code, historic of the sector and number of employees was proposed; a methodology was developed to evaluate the impact of the electrotherm substitution on the quality of the remaining electric energy, after the change, focusing on power factor and harmonics; a procedure for the field study was also proposed, identifying the final uses of the energy, the characteristics of the processes which use electrotherm, analyzing the limitations of these substitutions, the different operational costs according to the local concessionaries and how the energy has been contracted. This work identifies the existing policies and governmental programs for energetic efficiency and makes a critical analysis of them, as well as suggesting alternatives to the current energy model (core of electrotherm substitution), seeking to improve the synergy between policies and programs, in an attempt to show the electrotherm substitution as a huge potential to reduce the electric energy consumption in Brazil and a more rational use of fuel gases.
