Spiral Type Boiler Fin Tube Exported To Iran Assembly To Economizer For Industrial Boiler
1. Economiser performs a key function in providing high overall boiler thermal efficiency by recovering the low level energy from the flue gas before it is exhausted to the atmosphere.
2. Economiser recovers the energy by heating the boiler feedwater.
3. Economiser are basically tubular heat transfer surfaces used to preheat boiler feed water before it enters the steam drum or furnace surfaces.
4. Economiser reduces operating costs or economise on fuel by recovering extra energy from the flue gas.
5. Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.
6. We can manufacture three types of boiler economizer, bare tube economzier, H finned tube economzier and spiral finned tube economzier.
|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.
|Spiral Wrapped Fin|
|Each tube is individually finned||Increased thermal conductivity|
|Less fin material used|
|Ability to replace a single damaged tube|
|More compact fin bundle|
|Tube face and row centers can vary|
|Allows coil to better fit with existing case height|
|Pitch to drain a multi-row for vertical airflow|
|Tension Bond||Use various fin and tube materials|
|Use various fin and tube thicknesses|
|Embedded Fin||Maintain fin bond at high temperatures|
|Header||Accommodates header thermal expansion|
|Allows longer header stubs|
1.Our products can be modified according to our customers' needs and the situation.
|1||Impact test and Strength calculation report with applied materials information.|
|2||100%NDT(non-destructive inspection) report of steel plate, tube and electrode.|
|3||X-ray, γ-ray and liquid penetrant test inspection report (welding seam): to ensure the quality of the entire boiler.|
|4||Hydraulic test report: ensure the standard working pressure and safety.
