ANALYSIS OF ENERGY PERFORMANCE OF A COGENERATION SOURCE

Knowledge of energy performance indicators is essential to substantiate investment decisions in energy facilities. Energy audit is the procedure by which energy performance indicators can be assessed and identified measures to improve them. Considering the share and the potential to improve the efficiency of cogeneration sources for the production of thermal and electrical energy, the determination of their performance indicators based on energy audits is essential for achieving the goals of reducing energy consumption. This paper is a synthesis of the results obtained in performing the energy audit of a cogeneration source serving an industrial consumer. After describing the general framework, the justification of the concern and the presentation of the defining elements of characterization of the analyzed installation, the second part of the paper refers to the specificities of the applied complex energy balance model. Next, reference is made to the methodology for obtaining input quantities in energy balance models and mass balance sheets. The final part of the paper presents the results obtained, the values of the performance indicators, the measures for improving the energy efficiency and the general conclusions of the analysis.
