Product Description
CFB Boiler Spiral Finned Tube Cast Iron stack Economiser factory optional device High efficiency Annealing treatment
Spiral Finned Tube Economizer
The economizer can be installed at the rear of exhaust gas stovepipe to recovery exhaust gas heat,increase the electricity output,lower the coal consumption.spiral finned tube economizer is a new and efficient heat transfer equipment, which is a good solution to the light tube economizer because of badly worn, short life and other shortcomings.
Details
Heat transfer area can be greatly extended, reducing the volume and angle fittings, enhanced heat transfer. As gas flows through the finned tube forming the boundary layer, resulting in the vortex.Adapting to wide temperature, high pressure;impact resistance low flue gas resistance.
Characteristics
a) Dimensional range
| Diameter | 6 – 102 mm(0.24 – 4.02 in.) |
| Wall thickness | 0.3 – 9 mm(0.01 – 0.33 in.) |
| Length | up to 25,000 mm(984 in.) |
b) Annealing conditions
• Hard
• Annealed conforming to standards (soft, half-hard, blank, etc.)
• According to customer specifications
Purpose
Using an economizer does not just prevent heat loss — it can also extend the life of the boiler. Stresses from using cooler temperature make-up water, known as “thermal shock”, can subject wear and tear on the boiler’s structural integrity over time. This hammering “shock” effect occurs as the boiler’s fixed tube-sheets and fire-tubes rapidly contract from the sudden make-up of cooler temperature water. However, when this water is pre-heated, the temperature differential is far less extreme, putting less strain on the boiler and giving it a longer operating life.

High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler
High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler Product Introduction Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME Product Description The boiler economizer is a device used to recover waste heat in industrial boilers, usually located at the tail of the flue of the boiler, which increases the feed water temperature and reduces fuel consumption by absorbing the heat of the flue gas, so as to achieve the effect of energy saving and emission reduction. But at the same time, as an environmental protection equipment, the

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
