‌Customized Durable Boiler Fin Tubes With Spiral Design For Economizers

Product introduction

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.

Technical specifications

1.Construction structure
Consists of a serious of H type finned tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.

2.Structure Arrangement
In line / staggered arrangement.

How to prevent ash fouling?

Maintain flue gas velocity ≥8m/s and install soot blowers.

Specification

Functions

1.absorb heat from high temperature gas,reduce exhaust gas temperature,reduce gas consumption,save fuel.

2.feed water is heated in econimizer before enter into steam drum,so reduce heat absorption of feed water at heating surface,which can use economizer instead of high cost evaporation heating surface and saving cost.

3.Economizer increase feed water temperature,when feed water enter to steam drum,the wall temperature deviation are decreased,the thermal stress decrease accodingly and extend working life of drum.
