Note: The flue gas has a pressure of 120 kPa(G). Do not attempt to design this heat exchanger using so-called experience; in such cases, the flue gas pressure is usually very low, around 2-3 kPa(G). At the same time, the condensate water needs to be calculated. This design calculates automatically that condensate accounts for 9.19% (wt) of the total flue gas volume; the “empirical” value is also incorrect. This is the calculation report (Word format): Below is the design process:
