Boiler Pressure Parts CS/ND/Stainless Steel Boiler Fin Tube Heat Exchanger For Coal-fired Boiler Economizers
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:
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:
|Medium||air, flue gas, thermal oil, water, brine, refrigerant, etc.|
|Temperature||standard heat exchanger to 560 ° C by special materials can be higher|
|Pipe materials||carbon steel, stainless steel, alloy or special materials|
|Ribs materials||carbon steel, stainless steel, non-ferrous metal, alloy or special materials|
|Thermal insulation &Surface treatment||according to customers specification|
1. The equipment body can be designed into many modules to ensure the long term and stable running;
2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage
3. Improve the heat transfer efficiency
4. Structure arrangement: In line or staggered arrangement
