CS / ND / Stainless Steel Boiler Fin Tube Heat Exchanger For Boiler Economizers

Product Specification

Boiler Pressure Parts CS/ND/Stainless Steel Boiler Fin Tube Heat Exchanger For Coal-fired Boiler Economizers

Product Description

Finned tube is used to recover heat from flue gas exhaust of power plant boilers, industrial boilers, industrial kilns and marine power plants, make full use of waster heat, save energy, protect environment and reduce emissions, and improve fuel utilization rate, they are the strengthened heat exchange elements arranged at the tail of the fuel duct of the system.

There are spiral finned tubes and H-type finned tubes. Spiral finned tubes can further divided into high frequency resistance welding spiral finned tube, brazed spiral finned tube and integral spiral finned tube. 

Spirial Finned Tube:

Spiral finned tubes are widely used in heat recovery of boiler economizer, air preheater, and waste heat boiler, as well as heat exchange equipment in chemical industry, pressure vessel and other fields. The capacity of units used in boilers has also increased from small to large, and their applications are increasing day by day. At present, many professional manufacturers in China can produce high frequency resistance welding, brazing spiral finned tubes, and the production equipment and technology of finned tubes have been developed, designed and manufactured from importation, digestion and absorption to self-development. The quality has reached the requirements of advanced foreign standards.

Advantages of using finned tubes:

1. the heat transfer area is increased in the effective space to improve the heat transfer effect.

2. Reduce the occupancy space of heat transfer surface and reduce its volume, especially for fast-loading boilers.

3. Reduce the equipment cost and improve the safety of equipment.

4. Due to the decrease of water side pressure drop, the operation cost is reduced.

5. The stiffness of finned tubes are increased, and the seismic resistance of the tube is improved.

H-type Finned Tube:

Product Description:

H type finned tube is used to recover waster heat from flue gas exhaust of power plant boilers, industrial boilers, industrial kilns and marine power plant, make full use of waste heat, save energy and reduce emission to protect environment, improve fuel utilization rate, and they are the strengthened heat exchange elements arranged at the tail of the fuel duct of the system.

The utility model relates to a double H-type finned tube strengthened heat exchange element, which is characterized by:

• the fins are butt welded on the surface of the steel tube
• The contact of the fin welded parts adopts multiple zigzag shapes, the heating surface is is welded uniformly and firmly, the welding angle is formed uniformly and the surface is smooth, there is no slag inclusion pore weld, and the penetration rate reaches 97%.

Technical parameter

Features
