Product Description
Utility Boiler accessories gilled tube economizer coal fired Stainless steel seamless pipe
Product Description
Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler. Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency. By rapidly increasing feedwater temperature through captured flue gas, economizers also provide a significant improvement in steam generation and response time.
Technical specifications
Material Structure
Consists of a serious of spiral fin tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.
Structure Arrangement
In line / staggered arrangement.
Characteristics
1. This type of economizer can largely develop the heat exchanging area than the bare economizer to add the heat transfer area, reduce the volume, compact structure and reduce the number of elbow and welding to make less leakage and add the heat transfer efficiency.
2. Not easy to collect dust and the fume pass through the fin tube to form the boundary layer to occur the vortex to make less chance for the fly ash particle to touch the tube wall.
3. Widely temperature range, high pressure limit.
4. Durable strong impact, reliable operation.
5. less fume resistance, reduced abrasion and long working life.
6. Beautiful appearance, simple fabrication process.
7. Diverse layout.
8. Ease of installation, ease of construction.
9. A wide range of working pressure .

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
