Professional Stainless Steel Boiler Economizer For Heat Recovery H Fin Tube Economizer

Introduction of Boiler Economizer

We can manufacture three types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer. H-finned tube economizer is high efficient heat exchanger economizer which is consisted of H-finned tubes.
Compared with bare tube economizer, H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes. It also can increase the flue gas flow area in order to reduce the flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high rigidness to fit long tube row.
The spiral finned economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion and short service time.

1.Bare Tube Economizer

The bare tube economizer is a kind of economizer which is made from
seamless steel tube.
2.H-Finned Tube Economizer
H-finned tube economizer is high efficient heat exchanger
economizer which is consisted of H-finned tubes. H-finned tube
economizer can enlarge the heat exchange area and reduce the number
of tubes. It also can increase the flue gas flow area in order to
reduce the flue gas flow speed and abrasion.H-finned tube can be
made as double H finned tubes , with high rigidness to fit long
tube row.
3.Spiral Finned Tube Economizer
The spiral finned tube economizer is a newly designed heat transfer equipment, consists of spiral
fin tubes to overcome the serious
abrasion and short service time.

Procedure of Boiler Economizer

Economisers also reduce the potential of thermal shock and strong water temperature fluctuations as the feed water enters the drum or waterwalls. Increasingly stringent environmental regulations limiting nitrogen oxides and sulfur dioxide emission can also affect economizer design. The gas-side heat transfer coefficient is much less than water side heat transfer coefficient. To compensate this, outer surface of the tubes may be finned to increase the surface area of heat transfer.The ultimate goal of economizer design is to achieve the necessary heat transfer at minimum cost. A key design criterion for economizer is maximum allowable flue gas velocity. Higher velocity provide better heat transfer and reduce capital cost.
