Spiral Type Boiler Fin Tube Exported To Iran Assembly To Economizer For Industrial Boiler
Introduction
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.
Technical parameter
| 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 |

Features
Features
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.
