Coal Economizer for Power Boiler Application Finned tube heating
surface boiler spare parts
H Finned Tube Economizer
- Finned Tube----Square fin tube, H fin tube, rectangular fin tubes,
double H fin tubes
- H fin tube known as square fin tube, There are two type of H fin
tubes, one type with single tube, normal called square fin tube,
the other with Double tube, normal called rectangular fin tubes.
and also manufactured as per customers requirements. Due to
rectangular shapes, which can offer large surface area compared to
the Spiral Finned tubes. Due to larger surface area available,
these finned tubes are used mostly in Air Heating application to
reduce the overall size of the equipment.
- H fin tube is a kind of boiler parts, to have two steel circular
symmetry to be welded on fluorescent tubes to form fins positive
shap much like letter "H", so called H-fin tube. H-economizer
widely used in utility boilers, industrial boilers, marine power,
such as the tail of heat exchanger components.
Supplying Scope
- Fin tube Specification: Chinese GB customary or equivalent ASME
customary or others;
- Material: steel, stainless-steel, metallic element and alloy steel;
- Bare tube size: OD20mm-OD273mm;
- Fins Pitch: 3mm-30mm;
- Fins Height: 10mm-30mm;
- Fin thickness: 1-10mm;
- Other sizes of the finned tube will be discused with customers'
needs.
H Finned Tube Economizer
1. The Economizer is a device installed in the lower part of the
flue of the boiler to recover the waste heat of the exhausted flue
gas, and the boiler feed water is heated to the heated surface of
the saturated water under the steam drum pressure, because it
absorbs the heat from the high temperature flue gas, and cools down
the exhaust gas temperature of the flue gas saves energy and
improves efficiency, so it is called an economizer.
2.The steel tube type economizer is not limited by pressure and can
be used as a boiling type, and is generally made of a carbon steel
pipe having an outer diameter of 32 to 51 mm. Fins and ribs are
sometimes added to the tube to improve heat transfer. The steel
tube type economizer consists of horizontally arranged parallel
elbow tubes(known as serpentine tubes).
Economizers are mainly used in industry, and are gradually becoming
popular in agriculture and some related industries.
Performance characteristics:
- Glorious anti-wear performance
- Less fouling
- Compact house
- Welded Joints less
- Stability
