Thermal characteristics and structural features:
Due to the expansion of the outer wall of the fin heat transfer area, so the structure is compact, namely under the condition of the same thermodynamic conditions and space, you can pick and choose the less value of flue gas velocity between tube, but the smoke velocity should not be less than 6 m/S, general with 7 to 9 m/S;Due to the low flue gas flow rate, and thus reduce the fly ash particles in flue gas of economizer tube pipe explosion accident caused by the wear and tear, and ensure the safety of boiler operation;Due to the structure generally have arranged along the column (or using staggered arrangement) and large pipe distance and good or poor rooms filled with spiral finned effect, can reduce the possibility of dust, plugging ash, especially suitable for burning ash content is bigger but the bond ability weaker coal boiler;Due to the expanded the heat transfer area, economizer tube row number decreases, thus reducing the possibility of the welding work Si and solder joint leakage, improve the safety and reliability of the pressure parts Heat transfer condition in the same conditions, its weight is lighter, about 70% of the light tube economizer, the materials about 45% of the light tube economizer.
