Coal Fired CFB Boiler Economizer Water Heat H Finned Tube / Spiral Finned Tube

CFB bare tube economizer and H finned tube economizer and spiral finned tube economizer

Introduction

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. 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.
