Abstract: The main objective of this study is to comprehensively perform exergy analysis of the tunnel furnace and the tunnel dryer, which was selected as the control volume and involved in a brick production line. The analysis was based on the real data measured over a one-year period at a working brick factory with a daily production capacity of 392 tons of fired bricks. Energy and exergy efficiencies of the control volume were obtained to be 76.46% and 12.90% for dead state values of 25°C and 1.013 atm, respectively.

Keywords: brick factory; tunnel furnace; tunnel dryer; energy and exergy analysis.
