Dear experts: Our production line is equipped with a finned steam heat exchanger that is used for preheating the air in the production process. The current steam pressure is around 14.5 kg, and the steam consumption is approximately 10.5 T/h. The air volume supplied by the blower is 140,000 m3/h; there is a petal-shaped damper at the inlet of the blower, with an opening degree of around 60%. The temperature can be raised from 15°C at room temperature to about 170°C. I would like to know what the thermal efficiency of this finned heat exchanger is How is it calculated? Thank you!
