Today, the energy needs are increasing, but the limited amount of fossil energy resources existing and its harmful to the environment has led to the spread of alternative energy sources. The most reliable, easily accessible and inexpensive energy source among these alternative energy sources is accepted worldwide as the efficient use of energy. In this context, energy efficiency is defined as the reduction of energy consumption without causing a decrease in production quality and quantity. Most of the energy obtained from different sources is used in the industry sector. It is anticipated that energy efficiency can be reduced and efficiency will be increased through methods such as efficient use of energy in the industry, prevention of losses and leaks and recovery of waste energy. At the same time, efficient use of energy will make a great contribution to the economy of the country and the protection of the environment. In the industrial sector, especially not using waste heat is one of the most important causes of lost energy. In this study, the waste heat recovery systems are defined and the parameters affecting the thermal efficiency of the two types of waste heat recovery systems (heat wheel and recuperator) most used in the industry are investigated experimentally. Taguchi method was used to determine the optimum conditions in order to increase efficiency in the system examined, and the results were interpreted by analyzing. The optimum conditions for the heat wheel are found as 100% heat wheel turnover rate, 60% Fan 1 speed and 80% Fan 2 speed, while the recuperator is 50 ºC air inlet temperature, 60% Fan 1 speed and 80% Fan 2 speed. The highest efficiency values obtained as a result of verification experiments were calculated as 97% and 73% for heat wheel and recuperator systems, respectively. These values were recorded as the highest efficiency values in all experiments and showed the accuracy of the analyzes performed with the applicability of the Taguchi method.
