Design calculation of heat exchangers for heating compressed air with hot water
Thread Content
Heating compressed air with hot water – Design calculations for the heat exchanger: Shell side: Medium: 3 kg of compressed air, flow rate of 7500 Nm3/h; inlet temperature: 35°C, outlet temperature: 60°C. Governing program: Medium: Hot water. Inlet temperature: 90°C Water flow rate: Sufficient Calculations required: 1. Recommended type of heat exchanger 2. Heat exchange area of the heat exchanger
The post has received over a hundred views yet no replies. Many such applications exist; finned types are generally used in these cases, and the temperature of the gas outlet is sufficient compared to the temperature of the hot water. With such a low flow rate, if one takes into account the pressure drop, energy consumption, and compact size of the equipment, please refer to the forum link: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=163192&highlight=%D6%B5%B5%C
What was said upstairs is correct. This is a typical application area for finned tubes. Box-type multi-row finned tube structure.
