Investigation of irreversibility with CO2 emission measurement in industrial enamel furnace

Abstract

As energy consumption increases, particularly in industry, the need for energy efficiency brings the issue into the foreground. At the same time, increasing competitiveness, reducing energy costs, and decreasing impacts on the environment can only be achieved through energy efficiency. Therefore the efficiency of large energy consumers should be evaluated and necessary efficiency-improving projects must be realized. In this study of energy and exergy, an analysis of an enameling furnace is made. Enameling furnaces are a significant energy consumer in the production line of boilers. In the analysis, energy and exergy efficiencies are calculated to be 13% and 9%, respectively. The energy recovery potential of an enameling furnace is then debated. As part of an energy audit, efficiency projects are further described in detail and implementations are disclosed. After the efficiency projects are implemented, the energy and exergy analyses are redone and the efficiencies are recalculated at 28% and 20.3%, respectively. The CO2 savings potential is identified with projects that are implemented. In addition, the advantages of energy-efficient designs and energy-efficient purchasing are discussed in the chapter. Finally, recommendations are made to increase the performance and efficiency of the system.
