Exergy analyses of a tunnel furnace and a tunnel dryer

Theoretical Exergoenvironmental Analysis of a Tunnel Furnace and Drying System in a Brick Production

“…The exergy and energy efficiency values of the control volume were obtained to be 12.90% and 76.46% from the previous study of the authors [2]. The exergy analysis diagram is illustrated in Figure 2.…”

“…The exergy rates of the input streams of coal, electrical work transfer, air and clay body were 7575 kW, 372 kW, 53 kW and 3 kW, respectively. The exergy rates of the exit streams of ash on the kiln car, flue gas, dried brick bodies and fired bricks were determined as 830 kW, 103kW, 90 kW, 5 kW and 4 kW, respectively [2]. The fuel of the control system was crushed coal.…”

“…When the products are produced with less exergy than the environmental damage due to less waste emissions will be reduced [1]. The exergetic destructions may be accepted as useful although they result low exergetic efficiency [2]. In a rotary kiln used for plaster production, the exergetic efficiency of the thermal process was reported as 16%.…”
