ASTM A192/ASTM A179 Carbon Steel Seamless H Type Finned Tube For Boiler
Advantages of HH/H finned tube
1) The H-type finned tube economizer instead of the smooth tube economizer can increase the heat exchange area， reduce the number of tubes， increase the flue gas flow section， reduce the flue gas velocity and wear.
2) The H-type finned tube can be made into a "double H" type finned tube with double tubes， which has good structural rigidity and can be used in the case of long tube banks.
3) The H-type finned tube economizer is arranged in sequence. The H-type finned tube divides the space into several small areas， which has the function of flow equalizing and greatly reduces the wear
4) The best soot blowing effect can be obtained by forming a straight channel on both sides of H-shaped fins.
5) The space is compact， the overall weight is greatly reduced， and the cost is reduced
6) Energy saving and low power consumption: the economizer used for the generator unit can reduce the heat loss of exhaust gas of the generator by at least two thirds， and only consume 2-4kw per ton of steam
7) Simple operation and maintenance; labor saving: the economizer is assembled as a whole， with fewer moving parts， simple structure and easy installation. High level of automation， simple operation and maintenance， can reduce the number of operators.
