Advantages of finned tubes over plain tubes used in the economizer
Advantages of finned tubes over plain tubes used in the economizer:
1. The finned tube heat exchanger is more economical than Conventional Bare tube Exchanger.
2. The tube side pressure drop and fluid velocity is higher than the conventional bare tube exchanger, which prevent fouling inside the tubes.
3. The shell side pressure drop is some lesser but fluid velocity is higher than the conventional heat exchanger. Which safe the outer surface of tubes from fouling creation and fluid transfer time,
4. The shell diameter of finned tube Exchanger is lesser than Conventional bare tube heat exchanger, which saves sheet material and reduces the size of the shell, which helps to easily installation in the plant,
5. There is small inner diameter and less No. of tubes than conventional Heat exchanger to achieve same heat transfer rate so there using less amount of water to transfer heat from hot fluid.
