Heat exchange calculation between saturated steam and nitrogen
Thread Content
I would like to ask the teachers for the calculation formula for heat exchange between saturated steam and nitrogen gas. The nitrogen gas flow rate is 70,000 Nm3/h; the inlet temperature of the nitrogen gas is 10–30°C, while the outlet temperature is 150°C. The inlet pressure of the nitrogen gas is 0.108 Mpa, and the allowable pressure loss for the nitrogen gas is less than 1.2 kPa. The steam operates at a pressure of 0.9–1.2 Mpa, and the outlet temperature of the condensate water is around 80°C. Please carry out the calculation – you can also contact me via private message

I’ve done a rough calculation, for reference only. Below are the calculation interface and the generated calculation report. 70000*1.25=87500 kg/h
Question: Why is the heat transfer coefficient 500?

Just calculate it using HTFS
