The heat setting machine is one of the main energy-consuming equipment in the textile dyeing and finishing industry. The heat setting machine is a device that uses hot air to dry and finish fabrics and set them. There are many ways to supply hot air, which can directly burn coal gas or light diesel in the setting machine , or use circulating heat transfer oil or steam heating, or electric heating . Generally, the required hot air temperature in the heat setting machine is about 200°C . The exhaust gas temperature of the heat setting machine is generally around 170°C , and a large amount of waste heat is discharged into the air. If the fuel combustion loss and the body heat loss are added, it is estimated that more than 90% of the heat input into the heat setting machine is dissipated into the atmosphere from the exhaust gas. Heat treating the fabric actually consumed only heat setting machine input amount of 2.9% . The lost heat not only wastes energy but also causes environmental pollution. Therefore, the waste heat recovery of the heat setting machine is imperative.
