Fin Tube Economizer
I. What is a Fin Tube Economizer?
Fin tube economizers are highly efficient energy-saving devices widely used in coal-fired boilers, oil-fired boilers, and other boiler systems. They transfer heat from the flue gas to the working medium (water or air) through heat conduction by directing flue gas through the finned tubes, thereby improving the thermal efficiency of the device and reducing emission concentrations.
II. Fin Tube Economizer Specifications and Dimensions Table
The following is a table of commonly used specifications and dimensions for fin tube economizers for your reference.
| Model | Dimensions (L×W×H) | Fin Height | Fin Quantity |
|---|---|---|---|
| A | 1000mm×500mm×100mm | 8mm | 24 |
| B | 1200mm×600mm×150mm | 10mm | 44 |
| C | 1500mm×800mm×200mm | 12mm | 64 |
| D | 1800mm×1000mm×250mm | 14mm | 84 |
III. Fin Tube Economizer Parameters and Specifications
In addition to size, the parameters and specifications of a fin tube economizer are also factors to consider when selecting one.
1. Fin Pitch: The heat transfer efficiency of a fin tube is inversely proportional to the fin pitch. Generally speaking, a shorter fin pitch improves heat transfer efficiency, but it also increases resistance in the fin tube, affecting flue gas flow.
2. Fin Height: Fin height affects the thickness and weight of the finned tube. An appropriate fin height is generally selected to ensure structural stability and heat transfer efficiency.
3. Fin Shape: Different fin shapes affect the heat transfer efficiency and resistance of the finned tube. Common fin shapes include straight, wavy, and herringbone.
IV. Types of Finned Tube Economizers
Finned tube economizers are also diverse and can be divided into the following categories:
1. Water-Finned Tube Economizer: This economizer transfers heat from the flue gas to water, quickly converting the heat into steam or hot water. It is widely used in industrial production and daily life.
2. Air-Finned Tube Economizer: This economizer transfers heat from the flue gas to air, which is then delivered to the room or to a diurnal temperature control system via a fan, thereby achieving energy savings and reducing consumption.
3. Spiral-Finned Tube Economizer: This economizer utilizes a spiral finned tube structure to increase flue gas flow velocity and heat transfer efficiency. It is widely used in industries such as mining and chemical engineering.
