Steel Boiler Spiral Finned Tube Economizer Fin Tube SS400 Fin Tube heat exchanger finned tube
Finned Tube Economizer Overview
1. Fin tube boilers represent one of a number of pressurized equipment options used to heat water or convert water into steam under controlled conditions.
2. As in a water tube boiler, water passes through boiler tubes while combustion gases remain in the shell side, passing over the tube surfaces. Unlike conventional water tube boilers, however, the tubes in a fin tube boiler are fitted with fins, increasing the area available to transfer heat.
Product Advantage
1. Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2. H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the manufacturing cost.
Quality Control
1 Impact test and Strength calculation report with applied materials information.
2 100%NDT(non-destructive inspection) report of steel plate, tube and electrode.
3 X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler.
4 Hydraulic test report: ensure the standard working pressure and safety.
