Boiler Auxiliary Finned Tube Boiler Economizer
1. Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.
2. Economizers are thus named as a result of they will utilize the total heat of the fluid flow is hot, however not hot enough to be employed in the boiler, so the total heat recovery is additional helpful and improve boiler potency.
3. They are a tool fitted to a boiler that saves energy by victimisation exhaust gas from the boiler to heat the cold water accustomed fill it.
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.
