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.
